1-1. Overview of 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED
SWITCH
24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH, 24 Fast Ethernet + 2
Gigabit L2 Managed Switch, implemented 24 10/100Mbps TP + 2 Gigabit dual
media ports with TP/SFP, is a standard switch that meets all IEEE 802.3/u/x/z
Gigabit, Fast Ethernet and Ethernet specifications. The switch can be managed
through RS-232 serial port via directly connection, or through Ethernet port using
Telnet or Web-based management unit, associated with SNMP agent. With the
SNMP agent, the network administrator can logon the switch to monitor, configure
and control each port’s activity in a friendly way. The overall network management is
enhanced and the network efficiency is also improved to accommodate high
bandwidth applications. In addition, the switch features comprehensive and useful
function such as QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking,
Bandwidth Control, Port Security, SNMP/RMON and IGMP Snooping capability via
the intelligent software. It is suitable for both metro-LAN and office application.
10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE 802.3/u/x/z
Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver is a Gigabit
Ethernet port that fully complies with all IEEE 802.3z and 1000Base-SX/LX
standards.
For upgrading firmware, please refer to the Section 3-20 or Section 4-2-2 for more
details. The switch will not stop operating while upgrading firmware and after that,
the configuration keeps unchanged.

priority queue and packet transmission schedule using Weighted Round
Robin (WRR). User-defined weight classification of packet priority can be
based on either VLAN tag on packets or user-defined port priority.
Spanning Tree:
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree
Protocol) standards.
VLAN:
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active
VLANs and VLAN ID 1~4094.
Port Trunking:
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control:
Support ingress and egress per port bandwidth control.
Port Security:
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON:
SNMP agent and RMON MIB. In the device, SNMP agent is a client
software which is operating over SNMP protocol used to receive the
command from SNMP manager (server site) and echo the corresponded
data, i.e. MIB object. Besides, SNMP agent will actively issue TRAP
information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of
the SNMP MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON
MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643) and
so on.
IGMP Snooping:
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used
to establish the multicast groups to forward the multicast packet to the
member ports, and, in nature, avoid wasting the bandwidth while IP
multicast packets are running over the network.

ꢀ
͒ꢀTP Port and Cable Installation
⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used.
It means you do not have to tell from them, just plug it.
⇒ Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the
other end is connected to a network-aware device such as a workstation or a
server.
⇒ Repeat the above steps, as needed, for each RJ-45 port to be connected to a
Gigabit 10/100/1000 TP device.
Now, you can start having the switch in operation.
͒ꢀPower On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will
automatically convert the local AC power source to DC power. It does not matter
whether any connection plugged into the switch or not when power on, even
modules as well. After the power is on, all LED indicators will light up immediately
and then all off except the power LED still keeps on. This represents a reset of the
system.
ꢀ
͒ꢀFirmware Loading
After resetting, the bootstrap loader will load the firmware into the memory. It will
take about 30 seconds, after that, the switch will flash all the LED once and
automatically performs self-test and is in ready state.

at both sides of the chassis.
⇒
⇒
⇒
Wear a grounding device for electrostatic discharge.
Screw the mounting accessory to the front side of the switch (See Fig. 2-2).
Place the Chassis into the 19-inch wiring closet rail and locate it at the proper
position. Then, fix the Chassis by screwing it.
2-1-3. Cabling Requirements
To help ensure a successful installation and keep the network performance good,
please take a care on the cabling requirement. Cables with worse specification will
render the LAN to work poorly.

2-1-3-1. Cabling Requirements for TP Ports
⇒ For Fast Ethernet TP network connection
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters.
⇒ Gigabit Ethernet TP network connection
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters. Cat. 5e is recommended.
2-1-3-2. Cabling Requirements for 1000SX/LX SFP Module
It is more complex and comprehensive contrast to TP cabling in the fiber media.
Basically, there are two categories of fiber, multi mode (MM) and single mode (SM).
The later is categorized into several classes by the distance it supports. They are
SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there mainly are
LC and BiDi LC.
Gigabit Fiber with multi-mode LC SFP module
Gigabit Fiber with single-mode LC SFP module
Gigabit Fiber with BiDi LC 1310nm SFP module
Gigabit Fiber with BiDi LC 1550nm SFP module

2-1-3-3. Switch Cascading in Topology
ꢀ
͒ꢀTakes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch
cascading that you may up-link the switches unlimitedly. In practice, the network
extension (cascading levels & overall diameter) must follow the constraint of the
IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which
the limitations are the timing requirement from physical signals defined by 802.3
series specification of Media Access Control (MAC) and PHY, and timer from some
OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber
100Base-TX TP
100Base-FX Fiber
Round trip Delay: 4096
Round trip Delay: 512
Cat. 5 TP Wire:
Fiber Cable
11.12/m
10.10/m
Cat. 5 TP Wire: 1.12/m
TP to fiber Converter: 56
Fiber Cable:
1.0/m
:
Bit Time unit : 1ns (1sec./1000 Mega bit)
Bit Time unit: 0.01µs (1sec./100 Mega bit)
Table 2-2
Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices
must be within Round Trip Delay (bit times) in a half-duplex network segment
(collision domain). For full-duplex operation, this will not be applied. You may use
the TP-Fiber module to extend the TP node distance over fiber optic and provide the
long haul connection.
͒ꢀTypical Network Topology in Deployment
A hierarchical network with minimum levels of switch may reduce the timing delay
between server and client station. Basically, with this approach, it will minimize the
number of switches in any one path; will lower the possibility of network loop and
will improve network efficiency. If more than two switches are connected in the
same network, select one switch as Level 1 switch and connect all other switches to
it at Level 2. Server/Host is recommended to connect to the Level 1 switch. This is
general if no VLAN or other special requirements are applied.

Case1: All switch ports are in the same local area network. Every port can access
each other (See Fig. 2-3).
Fig. 2-3 No VLAN Configuration Diagram
If VLAN is enabled and configured, each node in the network that can communicate
each other directly is bounded in the same VLAN area.
Here VLAN area is defined by what VLAN you are using. The switch supports both
port-based VLAN and tag-based VLAN. They are different in practical deployment,
especially in physical location. The following diagram shows how it works and what
the difference they are.
Case2a: Port-based VLAN (See Fig.2-4).
Fig. 2-4 Port-based VLAN Diagram
1. The same VLAN members could not be in different switches.
2. Every VLAN members could not access VLAN members each other.
3. The switch manager has to assign different names for each VLAN groups
at one switch.

Case 2b: Port-based VLAN (See Fig.2-5).
Fig. 2-5 Port-based VLAN Diagram
1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.
2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could
access VLAN4 members.

2-1-4-1. Configuring the Management Agent through the Serial RS-232 Port
To perform the configuration through RS-232 console port, the switch’s serial port
must be directly connected to a DCE device, for example, a PC, through RS-232
cable with DB-9 connector. Next, run a terminal emulator with the default setting of
the switch’s serial port. With this, you can communicate with the switch.
In the switch, RS-232 interface only supports baud rate 57.6k bps with 8 data bits, 1
stop bit, no parity check and no flow control.
RS-232 DB-9 Connector
AC Line 100-240V 50/60 Hz
Default IP Setting:
IP address = 192.168.1.1
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254

Terminal or Terminal Emulator
To configure the switch, please follow the procedures below:
1. Find the RS-232 DB-9 cable with female DB-9 connector bundled.
Normally, it just uses pins 2, 3 and 7. See also Appendix B for more
details on Null Modem Cable Specifications.
2. Attaches the DB-9 female cable connector to the male serial RS-232
DB-9 connector on the switch.
3. Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial
port, running a terminal emulator supporting VT100/ANSI terminal with
The switch’s serial port default settings. For example,
Windows98/2000/XP HyperTerminal utility.
Note: The switch’s serial port default settings are listed as follows:

͒ꢀSet IP Address, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-7 CLI Management for details about factory setting. They are
default setting of IP address. You can first either configure your PC IP address or
change IP address of the switch, next to change the IP address of default gateway
and subnet mask.
For example, your network address is 10.1.1.0, and subnet mask is 255.255.255.0.
You can change the switch’s default IP address 192.168.1.1 to 10.1.1.1 and set the
subnet mask to be 255.255.255.0. Then, choose your default gateway, may be it is
10.1.1.254.

2-1-4-2. Configuring the Management Agent through the Ethernet Port
There are three ways to configure and monitor the switch through the switch’s
Ethernet port. They are CLI, Web browser and SNMP manager. The user interface
for the last one is NMS dependent and does not cover here. We just introduce the
first two types of management interface.
Default IP Setting:
IP = 192.168.1.1
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
Assign a reasonable IP address,
For example:
IP = 192.168.1.100

Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
Fig. 2-9
͒ꢀManaging L2 MANAGED SWITCH through Ethernet Port
Before you communicate with the switch, you have to finish first the
configuration of the IP address or to know the IP address of the switch. Then, follow
the procedures listed below.
1. Set up a physical path between the configured the switch and a PC by a
qualified UTP Cat. 5 cable with RJ-45 connector.
Note: If PC directly connects to the switch, you have to setup the same
subnet mask between them. But, subnet mask may be different for the PC
in the remote site. Please refer to Fig. 2-9 about the switch’s default IP
address information.
2. Run CLI or web browser and follow the menu. Please refer to Chapter 3
and Chapter 4.

2-1-5. IP Address Assignment
For IP address configuration, there are three parameters needed to be filled in.
They are IP address, Subnet Mask, Default Gateway and DNS.
IP address:
The address of the network device in the network is used for internetworking
communication. Its address structure looks is shown in the Fig. 2-11. It is “classful”
because it is split into predefined address classes or categories.
Each class has its own network range between the network identifier and host
identifier in the 32 bits address. Each IP address comprises two parts: network
identifier (address) and host identifier (address). The former indicates the network
where the addressed host resides, and the latter indicates the individual host in the
network which the address of host refers to. And the host identifier must be unique
in the same LAN. Here the term of IP address we used is version 4, known as IPv4.
32
Network identifier
Host identifier

With the class addressing, it divides IP address into three classes, class A, class B
and class C. The rest of IP addresses are for multicast and broadcast. The bit
length of the network prefix is the same as that of the subnet mask and is denoted
as IP address/X, for example, 192.168.1.0/24. Each class has its address range
described below.
Class A:
Address is less than 126.255.255.255. There are a total of 126 networks can be
defined because the address 0.0.0.0 is reserved for default route and 127.0.0.0/8 is
reserved for loopback function.
0
Network address
Host
Class B:
IP address range between 128.0.0.0 and 191.255.255.255. Each class B network
has a 16-bit network prefix followed 16-bit host address. There are 16,384 (2^14)/16
networks able to be defined with a maximum of 65534 (2^16 –2) hosts per network.

Class C:
IP address range between 192.0.0.0 and 223.255.255.255. Each class C network
has a 24-bit network prefix followed 8-bit host address. There are 2,097,152
(2^21)/24 networks able to be defined with a maximum of 254 (2^8 –2) hosts per
network.

Class D and E:
Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used
for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-
1 and is used for IP broadcast.
According to IANA (Internet Assigned Numbers Authority), there are three specific
IP address blocks reserved and able to be used for extending internal network. We
call it Private IP address and list below:
Class A
Class B
Class C
10.0.0.0 --- 10.255.255.255
172.16.0.0 --- 172.31.255.255
192.168.0.0 --- 192.168.255.255
Please refer to RFC 1597 and RFC 1466 for more information.
Subnet mask:
It means the sub-division of a class-based network or a CIDR block. The subnet is
used to determine how to split an IP address to the network prefix and the host
address in bitwise basis. It is designed to utilize IP address more efficiently and
ease to manage IP network.
For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default,
in which the first two bytes is with all 1s. This means more than 60 thousands of
nodes in flat IP address will be at the same network. It’s too large to manage
practically. Now if we divide it into smaller network by extending network prefix from
16 bits to, say 24 bits, that’s using its third byte to subnet this class B network. Now
it has a subnet mask 255.255.255.0, in which each bit of the first three bytes is 1.
It’s now clear that the first two bytes is used to identify the class B network, the third
byte is used to identify the subnet within this class B network and, of course, the last
byte is the host number.
Not all IP address is available in the sub-netted network. Two special addresses are
reserved. They are the addresses with all zero’s and all one’s host number. For
example, an IP address 128.1.2.128, what IP address reserved will be looked like?
All 0s mean the network itself, and all 1s mean IP broadcast.

In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128,
contains 126 members in the sub-netted network. Another is that the length of
network prefix equals the number of the bit with 1s in that subnet mask. With this,
you can easily count the number of IP addresses matched. The following table
shows the result.

Table 2-4
According to the scheme above, a subnet mask 255.255.255.0 will partition a
network with the class C. It means there will have a maximum of 254 effective
nodes existed in this sub-netted network and is considered a physical network in an
autonomous network. So it owns a network IP address which may looks like
168.1.2.0.
With the subnet mask, a bigger network can be cut into small pieces of network. If
we want to have more than two independent networks in a network, a partition to
the network must be performed. In this case, subnet mask must be applied.
29
Download from Www.Somanuals.com. All Manuals Search And Download.
For different network applications, the subnet mask may look like 255.255.255.240.
This means it is a small network accommodating a maximum of 15 nodes in the
network.
Default gateway:
For the routed packet, if the destination is not in the routing table, all the traffic is put
into the device with the designated IP address, known as default router. Basically, it
is a routing policy. The gateway setting is used for Trap Events Host only in the
switch.
For assigning an IP address to the switch, you just have to check what the IP
address of the network will be connected with the switch. Use the same network
address and append your host address to it.
Fig. 2-12
First, IP Address: as shown in the Fig. 2-12, enter “192.168.1.1”, for instance. For
sure, an IP address such as 192.168.1.x must be set on your PC.
Second, Subnet Mask: as shown in the Fig. 2-12, enter “255.255.255.0”. Any
subnet mask such as 255.255.255.x is allowable in this case.
DNS:
The Domain Name Server translates human readable machine name to IP address.
Every machine on the Internet has a unique IP address. A server generally has a
static IP address. To connect to a server, the client needs to know the IP of the
server. However, user generally uses the name to connect to the server. Thus, the
switch DNS client program (such as a browser) will ask the DNS to resolve the IP
address of the named server.

3. Operation of
Web-based Management
This chapter instructs you how to configure and manage the 24 FAST ETHERNET +
2 GIGABIT L2 MANAGED SWITCH through the web user interface it supports, to
access and manage the 24 10/100Mbps TP + 2 Gigabit dual media ports with
TP/SFP Fiber management Ethernet switch. With this facility, you can easily
access and monitor through any one port of the switch all the status of the switch,
including MIBs status, each port activity, Spanning tree status, port aggregation
status, multicast traffic, VLAN and priority status, even illegal access record and so
on.
The default values of the managed switch are listed in the table below:
IP Address
192.168.1.1
Subnet Mask
255.255.255.0
Default Gateway 192.168.1.254
Username
Password
admin
admin
Table 3-1
After the managed switch has been finished configuration in the CLI via the switch’s
serial interface, you can browse it. For instance, type http://192.168.1.1 in the
address row in a browser, it will show the following screen (see Fig.3-1) and ask you
inputting username and password in order to login and access authentication. The
default username and password are both “admin”. For the first time to use, please
enter the default username and password, and then click the <Login> button. The
login process now is completed.
Just click the link of “Forget Password” in WebUI (See Fig. 3-1) or input “Ctrl+Z” in
CLI’s login screen (See Fig. 4-1~4-2) in case the user forgets the manager’s
password. Then, the system will display a serial No. for the user. Write down this
Use this new password as ID and Password, and it will allow the user to login the
system with manager authority temporarily. Due to the limit of this new password,
the user only can login the system one time, therefore, please modify your
password immediately after you login in the system successfully.
In this login menu, you have to input the complete username and password
respectively, the switch will not give you a shortcut to username automatically. This
looks inconvenient, but safer.

In the switch, it supports a simple user management function allowing only one
administrator to configure the system at the same time. If there are two or more
users using administrator’s identity, the switch will allow the only one who logins first
to configure the system. The rest of users, even with administrator’s identity, can
only monitor the system. For those who have no administrator’s identity, can only
monitor the system. There are only a maximum of three users able to login
simultaneously in the switch.
To optimize the display effect, we recommend you use Microsoft IE 6.0 above,
Netscape V7.1 above or FireFox V1.00 above and have the resolution 1024x768.
The switch supported neutral web browser interface.

3-1-2. IP Configuration
IP configuration is one of the most important configurations in the switch. Without
the proper setting, network manager will not be able to manage or view the device.
The switch supports both manual IP address setting and automatic IP address
setting via DHCP server. When IP address is changed, you must reboot the switch
to have the setting taken effect and use the new IP to browse for web management
and CLI management.

Function description:
Set IP address, subnet mask, default gateway and DNS for the switch.
Parameter description:
DHCP Setting:
DHCP is the abbreviation of Dynamic Host Configuration Protocol. Here
DHCP means a switch to turn ON or OFF the function.
The switch supports DHCP client used to get an IP address automatically
if you set this function “Enable”. When enabled, the switch will issue the
request to the DHCP server resided in the network to get an IP address.
If DHCP server is down or does not exist, the switch will issue the
request and show IP address is under requesting, until the DHCP server
is up. Before getting an IP address from DHCP server, the device will not
continue booting procedures. If set this field “Disable”, you’ll have to
input IP address manually. For more details about IP address and DHCP,
please see the Section 2-1-5 “IP Address Assignment” in this manual.
Default: Disable

IP address:
Users can configure the IP settings and fill in new values if users set the
DHCP function “Disable”. Then, click <Apply> button to update.
When DHCP is disabled, Default: 192.168.1.1
If DHCP is enabled, this field is filled by DHCP server and will not allow
user manually set it any more.
Subnet mask:
Subnet mask is made for the purpose to get more network address
because any IP device in a network must own its IP address, composed
of Network address and Host address, otherwise can’t communicate with
other devices each other. But unfortunately, the network classes A, B,
and C are all too large to fit for almost all networks, hence, subnet mask
is introduced to solve this problem. Subnet mask uses some bits from
host address and makes an IP address looked Network address, Subnet
mask number and host address. It is shown in the following figure. This
reduces the total IP number of a network able to support, by the amount
of 2 power of the bit number of subnet number (2^ (bit number of subnet
number)).
32 bits
Network ID
Network ID
Host ID
Host ID
Subnet number
Subnet mask is used to set the subnet mask value, which should be the
same value as that of the other devices resided in the same network it
attaches.
For more information, please also see the Section 2-1-5 “IP Address
Assignment” in this manual.
Default: 255.255.255.0
Default gateway:
Set an IP address for a gateway to handle those packets that do not
meet the routing rules predefined in the device. If a packet does not meet
the criteria for other pre-defined path, it must be forwarded to a default
router on a default path. This means any packet with undefined IP
address in the routing table will be sent to this device unconditionally.
Default: 192.168.1.254

DNS:
It is Domain Name Server used to serve the translation between IP
address and name address.
The switch supports DNS client function to re-route the mnemonic name
address to DNS server to get its associated IP address for accessing
Internet. User can specify a DNS IP address for the switch. With this, the
switch can translate a mnemonic name address into an IP address.
There are two ways to specify the IP address of DNS. One is fixed mode,
which manually specifies its IP address, the other is dynamic mode,
which is assigned by DHCP server while DHCP is enabled. DNS can
help you easily remember the mnemonic address name with the
meaningful words in it. Default is no assignment of DNS address.
Default: 0.0.0.0

3-1-3. Time Configuration
The switch provides manual and automatic ways to set the system time via NTP.
Manual setting is simple and you just input “Year”, “Month”, “Day”, “Hour”, “Minute”
and “Second” within the valid value range indicated in each item. If you input an
invalid value, for example, 61 in minute, the switch will clamp the figure to 59.
NTP is a well-known protocol used to synchronize the clock of the switch system
time over a network. NTP, an internet draft standard formalized in RFC 1305, has
been adopted on the system is version 3 protocol. The switch provides four built-in
NTP server IP addresses resided in the Internet and a user-defined NTP server IP
address. The time zone is Greenwich-centered which uses the expression form of
GMT+/- xx hours.

NTP:
NTP is Network Time Protocol and is used to sync the network time
based Greenwich Mean Time (GMT). If use the NTP mode and select a
built-in NTP time server or manually specify an user-defined NTP server
as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically,
NTP does not update the time periodically without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone
first and then perform time sync via NTP because the switch will combine
this time zone offset and updated NTP time to come out the local time,
otherwise, you will not able to get the correct time. The switch supports
configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
Daylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time
lag or in advance in unit of hours, according to the starting date and the
ending date. For example, if you set the day light saving to be 1 hour.
When the time passes over the starting time, the system time will be
increased one hour after one minute at the time since it passed over. And
when the time passes over the ending time, the system time will be
decreased one hour after one minute at the time since it passed over.
The switch supports valid configurable day light saving time is –5 ~ +5
step one hour. The zero for this parameter means it need not have to
adjust current time, equivalent to in-act daylight saving. You don’t have to
set the starting/ending date as well. If you set daylight saving to be non-
zero, you have to set the starting/ending date as well; otherwise, the
daylight saving function will not be activated.
Default for Daylight Saving: 0.
The following parameters are configurable for the function Daylight
Saving and described in detail.

Function name:
Management Security Configuration
Function description:
The switch offers Management Security Configuration function. With this
function, the manager can easily control the mode that the user connects to
the switch. According to the mode, users can be classified into two types:
Those who are able to connect to the switch (Accept) and those who are
unable to connect to the switch (Deny). Some restrictions also can be placed
on the mode that the user connect to the switch, for example, we can decide
that which VLAN VID is able to be accepted or denied by the switch, the IP
range of the user could be accepted or denied by the switch, the port that the
user is allowed or not allowed to connect with the switch, or the way of
controlling and connecting to the switch via Http, Telnet or SNMP.
Fig. 3-7
Parameter description:
Name:
A name is composed of any letter (A-Z, a-z) and digit (0-9) with maximal
8 characters.
VID:
The switch supports two kinds of options for managed valid VLAN VID,
including “Any” and “Custom”. Default is “Any”. When you choose
“Custom”, you can fill in VID number. The valid VID range is 1~4094.

3-1-6. Virtual Stack
Function name:
Virtual Stack
Function description:
Virtual Stack Management(VSM) is the group management function. Through
the proper configuration of this function, switches in the same LAN will be
grouped automatically. And among these switch, one switch will be a master
machine, and the others in this group will become the slave devices.
VSM offers a simple centralized management function. It is not necessary to
remember the address of all devices; manager is capable of managing the
network with knowing the address of the Master machine. Instead of SNMP or
Telnet UI, VSM is only available in Web UI. While one switch becomes the
Master, two rows of buttons for group device will appear on the top of its Web
UI. By pressing these buttons, user will be allowed to connect the Web UI of
the devices of the group in the same window without the login of these devices.
The most top-left button is only for Master Device. The background color of the
button you press will be changed to represent that the device is under your
management.
Note: It will remove the grouping temporarily in case that you login the switch
via the console.
The device of the group will be shown as station address (the last number of
IP Address) + device name on the button, otherwise it will show ” ---- “ if no
corresponding device exists.
Once the devices join the group successfully, then they are merely able to be
managed via Master device, and user will fail to manage them via
telnet/console/web individually.
Up to 16 devices can be grouped for VSM; however, only one Master is
allowed to exist in each group. For Master redundancy, user may configure
more than two devices as Master device; however, the Master device with the
smaller MAC value will be the Master one. All of these 16 devices can
become Master device and back up with each other.

ports in the switch changes its parameter displayed in the page, it will be
automatically refreshed the port current status about every 5 seconds.
Parameter Description:
Port No:
Display the port number. The number is 1 – 26. Both port 25 and 26 are
optional modules.
Media:
Show the media type adopted in all ports. The Port 25 and Port 26 are
optional modules, which support either fiber or UTP media with either
Gigabit Ethernet (1000Mbps) or 10/100Mbps Fast Ethernet port. They
may have different media types and speed. Especially, fiber port has
comprehensive types of connector, distance, fiber mode and so on. The
switch describes the module ports with the following page.
Link:
Show that if the link on the port is active or not. If the link is connected to
a working-well device, the Link will show the link “Up”; otherwise, it will
show “Down”. This is determined by the hardware on both devices of the
connection.
No default value.
State:
Show that the communication function of the port is “Enabled” or
“Disabled”. When it is enabled, traffic can be transmitted and received via
this port. When it is disabled, no traffic can be transferred through this
port. Port State is configured by user.
Default: Enabled.
Auto Nego.:
Show the exchange mode of Ethernet MAC. There are two modes
supported in the switch. They are auto-negotiation mode “Enabled” and
forced mode “Disabled”. When in “Enabled” mode, this function will
automatically negotiate by hardware itself and exchange each other the
capability of speed and duplex mode with other site which is linked, and
comes out the best communication way. When in “Disabled” mode, both
parties must have the same setting of speed and duplex, otherwise, both
of them will not be linked. In this case, the link result is “Down”.
Default: Enabled

Speed / Duplex :
Display the speed and duplex of all port. There are three speeds 10Mbps,
100Mbps and 1000Mbps supported for TP media, and the duplex
supported is half duplex and full duplex. If the media is 1Gbps fiber, it is
1000Mbps supported only. The status of speed/duplex mode is
determined by 1) the negotiation of both local port and link partner in
“Auto Speed” mode or 2) user setting in “Force” mode. The local port has
to be preset its capability.
In port 1 – 24, they are supported Fast Ethernet with TP media only, so
the result will show 100M/Full or 100M/Half, 10M/Full and 10M/Half
duplex.
In port 25 and port 26, if the media is 1000Mbps with TP media, it will
show the combinations of 10/100M and Full/Half duplex, 1000Mbps and
Full duplex only. If the media is 1000Mbps with fiber media, it will show
only 1000M/Full duplex.
Default: None, depends on the result of the negotiation.
Rx Pause:

“on”, the port will care the PAUSE frame; otherwise, the port will ignore
the PAUSE frame.
Default: None
Tx Pause:
It decides that whether the port transmits the PAUSE frame or not. If it
shows “on”, the port will send PAUSE frame; otherwise, the port will not
send the PAUSE frame.
Default: None

3-3. SNMP Configuration
Any Network Management System (NMS) running the Simple Network
Management Protocol (SNMP) can manage the Managed devices equipped with
SNMP agent, provided that the Management Information Base (MIB) is installed
correctly on the managed devices. The SNMP is a protocol that is used to govern
the transfer of information between SNMP manager and agent and traverses the
Object Identity (OID) of the management Information Base (MIB), described in the
form of SMI syntax. SNMP agent is running on the switch to response the request
issued by SNMP manager.
Basically, it is passive except issuing the trap information. The switch supports a
switch to turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP
agent will be started up. All supported MIB OIDs, including RMON MIB, can be
accessed via SNMP manager. If the field SNMP is set “Disable”, SNMP agent will
be de-activated, the related Community Name, Trap Host IP Address, Trap and all
MIB counters will be ignored.
Function name:
SNMP Configuration
Function description:
This function is used to configure SNMP settings, community name, trap host and
public traps as well as the throttle of SNMP. A SNMP manager must pass the
authentication by identifying both community names, and then it can access the MIB
information of the target device. So, both parties must have the same community
name. Once completing the setting, click <Apply> button, the setting takes effect.
Parameters description:
SNMP:
The term SNMP here is used for the activation or de-activation of SNMP.
Default is Enable.
Get/Set/Trap Community:
Community name is used as password for authenticating if the
requesting network management unit belongs to the same community
group. If they both don’t have the same community name, they don’t
belong to the same group. Hence, the requesting network management
unit can not access the device with different community name via SNMP
protocol; If they both have the same community name, they can talk each
other.
Community name is user-definable with a maximum length of 15
characters and is case sensitive. There is not allowed to put any blank in
the community name string. Any printable character is allowable.
The community name for each function works independently. Each
function has its own community name. Say, the community name for
GET only works for GET function and can’t be applied to other function
such as SET and Trap.

Default SNMP function: Enable
Default community name for GET: public
Default community name for SET: private
Default community name for Trap: public
Default Set function: Enable
Default trap host IP address: 0.0.0.0
Default port number: 162
Trap:
In the switch, there are 6 trap hosts supported. Each of them has its own
community name and IP address; is user-definable. To set up a trap host
means to create a trap manager by assigning an IP address to host the
trap message. In other words, the trap host is a network management
unit with SNMP manager receiving the trap message from the managed
switch with SNMP agent issuing the trap message. 6 trap hosts can
prevent the important trap message from losing.
For each public trap, the switch supports the trap event Cold Start, Warm
Start, Link Down, Link Up and Authentication Failure Trap. They can be
enabled or disabled individually. When enabled, the corresponded trap
will actively send a trap message to the trap host when a trap happens. If
all public traps are disabled, no public trap message will be sent. As to
the Enterprise (no. 6) trap is classified as private trap, which are listed in
the Trap Alarm Configuration function folder.
Default for all public traps: Enable.

3-4. Loop Detection
Looping will always occur when the switches are connected as a cycle and a switch
transmits the packets that will go back to the transmitted switch. Loop Detection will
prevent the looping from happening. Moreover, it could remove the looping
phenomenon per port. In general, you can unplug the cable connection to stop the
looping when a port causes the looping. The switch has powerful Looping Detection
capability, which could cease the looping immediately.

looping detection. After enabling looping action, you should decide which
port you would like to open loop detection capability. For example, you
open the loop detection of port 1 as enable state. When the looping
situation happens from port 1, Loop Detection will lock the port1’s ability.
And then you will see that the “Current Status” of port 1 shows Locked. In
port status function, you can see that the State of Port Configuration of
port 1 is “Disabled”. So the port 1 will lose the essential ability the port
could have. However, “Resume Action” in Loop Detection will remove the
looping status. It is very convenient for looping happening in real
networking environment. After any setting you done, please click the
<Apply> button to have the setting taken effect. When looping has
already happened, we suggest that the users could choose the looping
port as “Enable” in advance. And then tick the check box (ꢀ) of the
Action. That will get the better result for Looping removing.
Parameters description:
State:
Open the Loop Detection capability per port. The list has “Enable” and
“Disable”. Default is “Disable”.
Current Status:
Show the looping status per port. It could be “Unlocked or Locked”.
Default is “Unlocked”. When some port happens looping, it will show
“Locked”
Resume Action:
Remove the looping status per port. Just tick the check box (ꢀ) of the
Unlock to open resume action per port.
Refresh:
“Refresh” button could appear the instant Current Status of Loop
Detection.

3-5. DHCP Boot
The DHCP Boot function is used to spread the request broadcast packet into a
bigger time frame to prevent the traffic congestion due to broadcast packets from
many network devices which may seek its NMS, boot server, DHCP server and
many connections predefined when the whole building or block lose the power and
then reboot and recover. At this moment, a bunch of switch or other network device
on the LAN will try its best to find the server to get the services or try to set up the
predefined links, they will issue many broadcast packets in the network.
The switch supports a random delay time for DHCP and boot delay for each device.
This suppresses the broadcast storm while all devices are at booting stage in the
same time. The maximum user-defined delay time is 30 sec. If DHCP Broadcasting
Suppression function is enabled, the delay time is set randomly, ranging from 0 to
30 seconds, because the exactly delay time is computed by the switch itself. The
default is “Disable”.

3-6. IGMP Snooping
The function, IGMP Snooping, is used to establish the multicast groups to forward
the multicast packet to the member ports, and, in nature, avoids wasting the
bandwidth while IP multicast packets are running over the network. This is because
a switch that does not support IGMP or IGMP Snooping can not tell the multicast
packet from the broadcast packet, so it can only treat them all as the broadcast
packet. Without IGMP Snooping, the multicast packet forwarding function is plain
and nothing is different from broadcast packet.
A switch supported IGMP Snooping with the functions of query, report and leave, a
type of packet exchanged between IP Multicast Router/Switch and IP Multicast Host,
can update the information of the Multicast table when a member (port) joins or
leaves an IP Multicast Destination Address. With this function, once a switch
receives an IP multicast packet, it will forward the packet to the members who
joined in a specified IP multicast group before.
The packets will be discarded by the IGMP Snooping if the user transmits multicast
packets to the multicast group that had not been built up in advance.
Fig. 3-18
Function name:
IGMP Snooping Status
Function description:
IGMP is used to snoop the status of IP multicast groups and display its
associated information in both tagged VLAN and non-tagged VLAN networks.
Enabling IGMP with either passive or active mode, you can monitor the IGMP
snooping information, which contains the multicast member list with the
multicast groups, VID and member port.

Parameter description:
IGMP snooping mode selection:
The switch supports three kinds of IGMP Snooping status, including
“Passive”, “Active” and “Disable”.
Disable:
Set “Disable” mode to disable IGMP Snooping function.
Default: Disable
Active:
In Active mode, IGMP snooping switch will periodically issue the
Membership Query message to all hosts attached to it and
gather the Membership report message to update the database
of the Multicast table. By the way, this also reduces the
unnecessary multicast traffic.
Passive:
In Passive Snooping mode, the IGMP snooping will not
periodically poll the hosts in the groups. The switch will send a
Membership Query message to all hosts only when it has
received a Membership Query message from a router.
IP Address:
Show all multicast groups IP addresses that are registered on this device.
VLAN ID:
Show VLAN ID for each multicast group.
Member Port:
Show member ports that join each multicast group. Member port may be
only or more than one.

3-7. VLAN
The switch supports Tag-based VLAN (802.1q) and Port-based VLAN. It supports
256 active VLANs and VLAN ID 1~4094. VLAN configuration is used to partition
your LAN into small ones as your demand. Properly configuring it, you can gain not
only improving security and increasing performance but greatly reducing VLAN
management.
3-7-1. VLAN Mode
Function name:
VLAN Mode Setting
Function description:
The VLAN Mode Selection function includes two modes: Port-based and Tag-
based, you can choose one of them by pulling down list and pressing the
<Downward> arrow key. Then, click <Apply> button, the settings will take
effect immediately.
Parameter description:
VLAN Mode:
Tag-based:
This is the default setting.
Tag-based VLAN identifies its member by VID. This is quite
different from port-based VLAN. If there are any more rules in
ingress filtering list or egress filtering list, the packet will be
screened with more filtering criteria to determine if it can be
forwarded. The switch supports supplement of 802.1q.
Each tag-based VLAN you built up must be assigned VLAN name
and VLAN ID. Valid VLAN ID is 1-4094. User can create total up to
256 Tag VLAN groups.
Port-based:
Port-based VLAN is defined by port. Any packet coming in or
outgoing from any one port of a port-based VLAN will be accepted.
No filtering criterion applies in port-based VLAN. The only criterion
is the physical port you connect to. For example, for a port-based
VLAN named PVLAN-1 contains port members Port 1&2&3&4. If
you are on the port 1, you can communicate with port 2&3&4. If you
are on the port 5, then you cannot talk to them. Each port-based
VLAN you built up must be assigned a group name. This switch can
support up to maximal 26 port-based VLAN groups.
Metro Mode:
The Metro Mode is a quick configuration VLAN environment
method on Port-based VLAN. It will create 22 or 23 Port-based
VLAN groups.
74
Download from Www.Somanuals.com. All Manuals Search And Download.
Symmetric Vlan:
This is an Ingress Rule (Rule 1, The Ingress Filtering Rule 1 is “forward
only packets with VID matching this port’s configured VID”.). For example,
if port 1 receives a tagged packet with VID=100 (VLAN name=VLAN100),
and if Symmetric-Vlan function is enabled, the switch will check if port 1
is a member of VLAN100. If yes, the received packet is forwarded;
otherwise, the received packet is dropped.
Note: If Symmetric is enabled and port 1, for example, receives an untagged packet,
the switch will apply the PVID of port 1 to tag this packet, the packet then will
be forwarded. But if the PVID of port 1 is not 100, the packet will be dropped.
SVL:
While SVL is enable, all VLANs use the same filtering database storing
the membership information of the VLAN to learn or look up the
membership information of the VLAN. While SVL is disable, it means
learning mode is IVL. In this mode, different VLAN uses different filtering
database storing the membership information of the VLAN to learn or
look up the information of a VLAN member.
Double Tag:
Double-tag mode belongs to the tag-based mode, however, it would treat
all frames as the untagged ones, which means that tag with PVID will be
added into all packets. Then, these packets will be forwarded as Tag-
based VLAN. So, the incoming packets with tag will become the double-
tag ones. To notice that the up-link Port won’t add an extra VLAN tag.
Up-link Port:
This function is enabled only when metro mode or double-tag is chosen
in VLAN mode.
25:
Except Port 25, each port of the switch cannot transmit packets with
each other. Each port groups a VLAN with Port 25, thus, total 23
groups consisting of 2 members are formed.
26:
Except Port 26, each port of the switch cannot transmit packets with
each other. Each port groups a VLAN with Port 26, thus, total 23
groups consisting of 2 members are formed.
25&26:
Except Port 25 and Port 26, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port 25
and Port 26, thus, total 22 groups consisting of 3 members are
formed.

number is from 1 to 4094. User also can choose ingress filtering rule (Rule 2)
to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule
2 is enabled, the port will discard all Untagged-frames.
Fig. 3-23
Parameter description:
Port 1-26:
Port number.
PVID:
This PVID range will be 1-4094. Before you set a number x as PVID, you
have to create a Tag-based VLAN with VID x. For example, if port x
receives an untagged packet, the switch will apply the PVID (assume as
VID y) of port x to tag this packet, the packet then will be forwarded as
the tagged packet with VID y.
Default Priority:
79
Download from Www.Somanuals.com. All Manuals Search And Download.
It bases on 802.1p QoS and affects untagged packets. When the packets
enter the switch, it would get the priority precedence according to your
Default Priority setting and map to 802.1p priority setting in QoS function.
For example, while you set Default Priority of port 2 with 2 and transmit
untagged packets to port 2, these packets will own priority 2 precedence
due to your default 802.1p Priority Mapping setting in QoS function and
be put into Queue 1.
Drop Untag:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged frame. If the former is the
case, then the packets with tagged or untagged will be processed. If the
later is the case, only the packets carrying VLAN tag will be processed,
the rest packets will be discarded.

3-9. GVRP Configuration
GVRP is an application based on Generic Attribute Registration Protocol (GARP),
mainly used to automatically and dynamically maintain the group membership
information of the VLANs. The GVRP offers the function providing the VLAN
registration service through a GARP application. It makes use of GARP Information
Declaration (GID) to maintain the ports associated with their attribute database and
GARP Information Propagation (GIP) to communicate among switches and end
stations. With GID information and GIP, GVRP state machine maintain the contents
of Dynamic VLAN Registration Entries for each VLAN and propagate these
information to other GVRP-aware devices to setup and update their knowledge
database, the set of VLANs associated with currently active members, and through
which ports these members can be reached.

3-10. STP Configuration
The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for
avoiding loops in switched networks. When STP is enabled, ensure that only one
path is active between any two nodes on the network at a time. User can enable
Spanning Tree Protocol on switch’s web management and then set up other
advanced items. We recommend that you enable STP on all switches to ensure a
single active path on the network.
3-10-1. STP Status
Function name:

Root Port:
Show port number connected to root bridge with the lowest path cost.
Root Path Cost:
Show the path cost between the root port and the designated port of the
root bridge.
Current Max. Age:
Show the current root bridge maximum age time. Maximum age time is
used to monitor if STP topology needs to change. When a bridge does
not receive a hello message from root bridge until the maximum age time
is counted down to 0, the bridge will treat the root bridge malfunctioned
and issue a Topology Change Notification (TCN) BPDU to all other
bridges.

Hello Time:
Show the current hello time of the root bridge. Hello time is a time
interval specified by Root Bridge, used to request all other bridges
periodically sending hello message every “hello time” seconds to the
bridge attached to its designated port.
STP Topology Change Count:
STP Topology Change Count expresses the time spent in unit of seconds
since the beginning of the Spanning Tree Topology Change to the end of
the STP convergence. Once the STP change is converged, the Topology
Change count will be reset to 0. The figures showing in the screen may
not be the exact time it spent but very close to, because the time is
eclipsing.
Time Since Last Topology Change:
Time Since Last Topology Change is the accumulated time in unit of
seconds the STP has been since the last STP Topology Change was
made. When Topology Change is initiated again, this counter will be
reset to 0. And it will also count again once STP topology Change is
completed.

3-10-2. STP Configuration
The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning Tree
Configuration, there are six parameters open for the user to configure as user’s idea.
Each parameter description is listed below.
Function name:
STP Configuration
Function description:
User can set the following Spanning Tree parameters to control STP function
enable/disable, select mode RSTP/STP and affect STP state machine
behavior to send BPDU in this switch. The default setting of Spanning Tree
Protocol is “Disable”.
Parameter description:
Spanning Tree Protocol:
Set 802.1W Rapid STP function Enable / Disable. Default is “Disable”
Bridge Priority:
The lower the bridge priority is the higher priority it has. Usually, the
bridge with the highest bridge priority is the root. If you want to have the
24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH as root
bridge, you can set this value lower than that of bridge in the LAN. The
valid value is 0 ~ 61440. The default is 32768.
Hello Time:
Hello Time is used to determine the periodic time to send normal BPDU
from designated ports among bridges. It decides how long a bridge
should send this message to other bridge to tell I am alive. When the 24
FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH is the root
bridge of the LAN, for example, all other bridges will use the hello time
assigned by this switch to communicate with each other. The valid value
is 1 ~ 10 in unit of second.
Default is 2 seconds.
Max. Age:
When the 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH is
the root bridge, the whole LAN will apply this figure set by this switch as
their maximum age time. When a bridge received a BPDU originated
from the root bridge and if the message age conveyed in the BPDU
exceeds the Max. Age of the root bridge, the bridge will treat the root
bridge malfunctioned and issue a Topology Change Notification (TCN)
BPDU to all other bridges. All bridges in the LAN will re-calculate and
determine who the root bridge is. The valid value of Max. Age is 6 ~ 40
seconds. Default is 20 seconds.

Forward Delay:
You can set the root bridge forward delay time. This figure is set by Root
Bridge only. The forward delay time is defined as the time spent from
Listening state moved to Learning state and also from Learning state
moved to Forwarding state of a port in bridge. The forward delay time
contains two states, Listening state to Learning state and Learning state
to Forwarding state. It assumes that forward delay time is 15 seconds,
and then total forward delay time will be 30 seconds. This has much to
do with the STP convergent time which will be more than 30 seconds
because some other factors.
The valid value is 4 ~ 30 seconds, default is 15 seconds.
Force Version:
Two options are offered for the user’s choosing STP algorithm. One is
RSTP and the other is STP. If STP is chosen, RSTP will run as a legacy
STP. The switch supports RSTP (802.1w) which is backward compatible
with STP (802.1d).

3-10-3. STP Port Configuration
Function name:
STP Port Setting
Function description:
In the STP Port Setting, one item selection and five parameters settings are
offered for user’s setup. User can disable and enable each port by selecting
each Port Status item. User also can set “Path Cost” and “Priority” of each port
by filling in the desired value and set “Admin Edge Port” and “Admin Point To
Point” by selecting the desired item.
Parameter description:
Port Status:
It displays the current state of a port. We cannot manually set it because
it displays the status only. There are three possible states. (According to
802.1w specification)
ꢀ DISCARDING state indicates that this port can neither forward packets
nor contribute learning knowledge.
Notice: Three other states (Disable state, BLOCKING state and LISTENING
state) defined in the 802.1d specification are now all represented as
DISCARDING state.
ꢀ LEARNING state indicates this port can now contribute its learning
knowledge but cannot forward packets still.
ꢀ FORWARDING state indicates this port can both contribute its learning
knowledge and forward packets normally.
Path Cost Status:
It is the contribution value of the path through this port to Root Bridge.
STP algorithm determines a best path to Root Bridge by calculating the
sum of path cost contributed by all ports on this path. A port with a
smaller path cost value would become the Root Port more possibly.
Configured Path Cost:
The range is 0 – 200,000,000. In the switch, if path cost is set to be zero,
the STP will get the recommended value resulted from auto-negotiation
of the link accordingly and display this value in the field of Path Cost
Status. Otherwise, it may show the value that the administrator set up in
Configured Path Cost and Path Cost Status.

802.1w RSTP recommended value: (Valid range: 1 – 200,000,000)
10 Mbps : 2,000,000
100 Mbps : 200,000
1 Gbps : 20,000
Default: 0
Priority:
Priority here means Port Priority. Port Priority and Port Number are
mixed to form the Port ID. Port IDs are often compared in order to
determine which port of a bridge would become the Root Port. The range
is 0 – 240.
Default is 128.
Admin Edge Port:
If user selects “Yes”, this port will be an edge port. An Edge Port is a port
connected to a device that knows nothing about STP or RSTP. Usually,
the connected device is an end station. Edge Ports will immediately
transit to forwarding state and skip the listening and learning state
because the edge ports cannot create bridging loops in the network. This
will expedite the convergence. When the link on the edge port toggles,
the STP topology keeps unchanged. Unlike the designate port or root
port though, an edge port will transit to a normal spanning-tree port
immediately if it receives a BPDU.
Default: No
Admin Point To Point:
We say a port is a point-to-point link, from RSTP’s view, if it is in full-
duplex mode but is shared link if it is in half-duplex mode. RSTP fast
convergence can only happen on point-to-point links and on edge ports.
This can expedite the convergence because this will have the port fast
transited to forwarding state.
There are three parameters, Auto, True and False, used to configure the
type of the point-to-point link. If configure this parameter to be Auto, it
means RSTP will use the duplex mode resulted from the auto-negotiation.
In today’s switched networks, most links are running in full-duplex mode.
For sure, the result may be half-duplex, in this case, the port will not fast
transit to Forwarding state. If it is set as True, the port is treated as point-
to-point link by RSTP and unconditionally transited to Forwarding state. If
it is set as False, fast transition to Forwarding state will not happen on
this port.
Default: Auto

M Check:
Migration Check. It forces the port sending out an RSTP BPDU instead
of a legacy STP BPDU at the next transmission. The only benefit of this
operation is to make the port quickly get back to act as an RSTP port.
Click <M Check> button to send a RSTP BPDU from the port you
specified.

3-11. Trunking Configuration
The Port Trunking Configuration is used to configure the settings of Link
Aggregation. You can bundle more than one port with the same speed, full duplex
and the same MAC to be a single logical port, thus the logical port aggregates the
bandwidth of these ports. This means you can apply your current Ethernet
equipments to build the bandwidth aggregation. For example, if there are three
Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth
three times as high as a single Fast Ethernet port has.
The switch supports two kinds of port trunking methods:
LACP:
Ports using Link Aggregation Control Protocol (according to IEEE
802.3ad specification) as their trunking method can choose their unique
LACP GroupID (1~3) to form a logic “trunked port”. The benefit of using
LACP is that a port makes an agreement with its peer port before it
becomes a ready member of a “trunk group” (also called aggregator).
LACP is safer than the other trunking method - static trunk.
The switch LACP does not support the followings:
Link Aggregation across switches
Aggregation with non-IEEE 802.3 MAC link
Operating in half-duplex mode
Aggregate the ports with different data rates
Static Trunk:
Ports using Static Trunk as their trunk method can choose their unique
Static GroupID (also 1~3, this Static groupID can be the same with
another LACP groupID) to form a logic “trunked port”. The benefit of
using Static Trunk method is that a port can immediately become a
member of a trunk group without any handshaking with its peer port. This
is also a disadvantage because the peer ports of your static trunk group
may not know that they should be aggregate together to form a “logic
trunked port”. Using Static Trunk on both end of a link is strongly
recommended. Please also note that low speed links will stay in “not
ready” state when using static trunk to aggregate with high speed links.
As to system restrictions about the port aggregation function on the switch,
In the management point of view, the switch supports maximum 3 trunk groups for
LACP and additional 3 trunk groups for Static Trunk. But in the system capability
view, only 3 “real trunked” groups are supported. An LACP trunk group with more
than one ready member-port is a “real trunked” group. An LACP trunk group with
only one or less than one ready member-port is not a “real trunked” group. Any
Static trunk group is a “real trunked” group.

Per Trunking Group supports a maximum of 4 ready member-ports. Please note
that some decisions will automatically be made by the system while you are
configuring your trunking ports. Trunk Setting Rules are listed below:
Rule1: Maximum 3 groups are allowed
Rule 2: The members of each group cannot exceed more than 4 ports
Rule 3: Group 1 and 2 cannot exist member 25 and 26 port
Rule 4: Group 3 cannot exist member from 1 to 24 port

Function name:
Port Setting/Status
Function description:
Port setting/status is used to configure the trunk property of each and every
port in the switch system.
Parameter description:
Method:
This determines the method a port uses to aggregate with other ports.
None:
A port does not want to aggregate with any other port should
choose this default setting.
LACP:
A port use LACP as its trunk method to get aggregated with other
ports also using LACP.
Static:
A port use Static Trunk as its trunk method to get aggregated with
other ports also using Static Trunk.
Group:
Ports choosing the same trunking method other than “None” must be
assigned a unique Group number (i.e. Group ID, valid value is from 1 to
8) in order to declare that they wish to aggregate with each other.
Active LACP:
This field is only referenced when a port’s trunking method is LACP.
Active:
An Active LACP port begins to send LACPDU to its link partner right
after the LACP protocol entity started to take control of this port.
Passive:
A Passive LACP port will not actively send LACPDU out before it
receives an LACPDU from its link partner.

Aggtr:
Aggtr is an abbreviation of “aggregator”. Every port is also an aggregator,
and its own aggregator ID is the same as its own Port No. We can regard
an aggregator as a representative of a trunking group. Ports with same
Group ID and using same trunking method will have the opportunity to
aggregate to a particular aggregator port. This aggregator port is usually
the port with the smallest Port No. within the trunking group.
Status:
This field represents the trunking status of a port which uses a trunking
method other than “None”. It also represents the management link status
of a port which uses the “None” trunking method. “---“ means “not ready”

3-12. 802.1x Configuration
802.1x port-based network access control provides a method to restrict users to
access network resources via authenticating user’s information. This restricts users
from gaining access to the network resources through a 802.1x-enabled port
without authentication. If a user wishes to touch the network through a port under
802.1x control, he (she) must firstly input his (her) account name for authentication
and waits for gaining authorization before sending or receiving any packets from a
802.1x-enabled port.
Before the devices or end stations can access the network resources through the
ports under 802.1x control, the devices or end stations connected to a controlled
port send the authentication request to the authenticator, the authenticator pass the
request to the authentication server to authenticate and verify, and the server tell
the authenticator if the request get the grant of authorization for the ports.
According to IEEE802.1x, there are three components implemented. They are
Authenticator, Supplicant and Authentication server.
Supplicant:
It is an entity being authenticated by an authenticator. It is used to
communicate with the Authenticator PAE (Port Access Entity) by
exchanging the authentication message when the Authenticator PAE
request to it.
Authenticator:
An entity facilitates the authentication of the supplicant entity. It controls
the state of the port, authorized or unauthorized, according to the result
of authentication message exchanged between it and a supplicant PAE.
The authenticator may request the supplicant to re-authenticate itself at a
configured time period. Once start re-authenticating the supplicant, the
controlled port keeps in the authorized state until re-authentication fails.
A port acting as an authenticator is thought to be two logical ports, a
controlled port and an uncontrolled port. A controlled port can only pass
the packets when the authenticator PAE is authorized, and otherwise, an
uncontrolled port will unconditionally pass the packets with PAE group
MAC address, which has the value of 01-80-c2-00-00-03 and will not be
forwarded by MAC bridge, at any time.
Authentication server:
A device provides authentication service, through EAP, to an
authenticator by using authentication credentials supplied by the
supplicant to determine if the supplicant is authorized to access the
network resource.

The overview of operation flow is quite simple. When Supplicant PAE
issues a request to Authenticator PAE, Authenticator and Supplicant
exchanges authentication message. Then, Authenticator passes the
request to RADIUS server to verify. Finally, RADIUS server replies if the
request is granted or denied.
While in the authentication process, the message packets, encapsulated
by Extensible Authentication Protocol over LAN (EAPOL), are exchanged
between an authenticator PAE and a supplicant PAE. The Authenticator
exchanges the message to authentication server using EAP
encapsulation. Before successfully authenticating, the supplicant can
only touch the authenticator to perform authentication message
exchange or access the network from the uncontrolled port.

This is the typical configuration, a single supplicant, an authenticator and an
authentication server. B and C is in the internal network, D is Authentication server
running RADIUS, switch at the central location acts Authenticator connecting to PC
A and A is a PC outside the controlled port, running Supplicant PAE. In this case,
PC A wants to access the services on device B and C, first, it must exchange the
authentication message with the authenticator on the port it connected via EAPOL
packet. The authenticator transfers the supplicant’s credentials to Authentication
server for verification. If success, the authentication server will notice the
authenticator the grant. PC A, then, is allowed to access B and C via the switch. If
there are two switches directly connected together instead of single one, for the link
connecting two switches, it may have to act two port roles at the end of the link:
authenticator and supplicant, because the traffic is bi-directional.

The Figure shows the procedure of 802.1x authentication. There are steps for the
login based on 802.1x port access control management. The protocol used in the
right side is EAPOL and the left side is EAP.
1.
At the initial stage, the supplicant A is unauthenticated and a port
on switch acting as an authenticator is in unauthorized state. So the
access is blocked in this stage.
2.
Initiating a session. Either authenticator or supplicant can initiate
the message exchange. If supplicant initiates the process, it sends
EAPOL-start packet to the authenticator PAE and authenticator will
immediately respond EAP-Request/Identity packet.
3.
4.
5.
The authenticator always periodically sends EAP-Request/Identity
to the supplicant for requesting the identity it wants to be
authenticated.
If the authenticator doesn’t send EAP-Request/Identity, the
supplicant will initiate EAPOL-Start the process by sending to the
authenticator.
And next, the Supplicant replies an EAP-Response/Identity to the
authenticator. The authenticator will embed the user ID into Radius-
Access-Request command and send it to the authentication server
for confirming its identity.
6.
7.
After receiving the Radius-Access-Request, the authentication
server sends Radius-Access-Challenge to the supplicant for asking
for inputting user password via the authenticator PAE.
The supplicant will convert user password into the credential
information, perhaps, in MD5 format and replies an EAP-Response
with this credential information as well as the specified
authentication algorithm (MD5 or OTP) to Authentication server via
the authenticator PAE. As per the value of the type field in message
PDU, the authentication server knows which algorithm should be
applied to authenticate the credential information, EAP-MD5
(Message Digest 5) or EAP-OTP (One Time Password) or other
else algorithm.

8.
9.
If user ID and password is correct, the authentication server will
send a Radius-Access-Accept to the authenticator. If not correct,
the authentication server will send a Radius-Access-Reject.
When the authenticator PAE receives a Radius-Access-Accept, it
will send an EAP-Success to the supplicant. At this time, the
supplicant is authorized and the port connected to the supplicant
and under 802.1x control is in the authorized state. The supplicant
and other devices connected to this port can access the network. If
the authenticator receives a Radius-Access-Reject, it will send an
EAP-Failure to the supplicant. This means the supplicant is failed to
authenticate. The port it connected is in the unauthorized state, the
supplicant and the devices connected to this port won’t be allowed
to access the network.
10. When the supplicant issue an EAP-Logoff message to
Authentication server, the port you are using is set to be
unauthorized.

3-17. QoS(Quality of Service) Configuration
The switch supports 5 kinds of QoS, are as follows, MAC Priority, 802.1p Priority, IP
TOS Priority, and DiffServ DSCP Priority. Port Based Priority has a special name
called VIP Port in the switch. Any packets enter VIP Port will have highest
transmitting priority. MAC Priority act on the destination address of MAC in packets.
VLAN tagged Priority field is affected by 802.1p Priority setting. IP TOS Priority
affects TOS fields of IP header, and you can find it has 8-bit SERVICE TYPE field
that specifies how the datagram should be handled. The field could be divided into
six subfields as follows, PRECEDENCE (3 bits), D-Type (Delay Priority, 1 bit), T-
Type (Throughput Priority, 1bit), R-Type (Reliability Priority, 1bit), M-Type (Monetary
Cost Priority, 1bit), and UNUSED (1bit).
User can randomly control these fields to achieve some special QoS goals. When
bits D, T, R, or M set, the D bit requests low delay, the T bit requests high
throughput, the R bit requests high reliability, and the M bit requests low cost.
DiffServ DSCP Priority act on DSCP field of IP Header. In the late 1990s, the IETF
redefined the meaning of the 8-bit SERVICE TYPE field to accommodate a set of
differentiated services (DS). Under the differentiated services interpretation, the first
six bits comprise a codepoint, which is sometimes abbreviated DSCP, and the last
two bits are left unused.
High Priority Packet streams will experience less delay into the switch. For handing
different priority packets, each egress port has designed up to 4 queues. Each QoS
is influenced by two scheduling, WRR (Weighted Round Robin) and Strict Priority as
well. When you finish setting the priority mapping to the queue, WRR scheduling will
distribute the bandwidth according to the weight you set for 4 queues (queue 0 to
queue 3). Another scheduling is Strict Priority dedicated for the function named VIP
Port of QoS. While we select some ports as the VIP Port, these ports will own the
highest transmitting priority in egress queue of the switch.

The QoS functions as we mentioned above are able to enable at the same time. But,
the following precedence will decide whether these functions work or not.
1. enable both VIP and TOS
Choose priorities of VIP and TOS.
2. enable both VIP and DSCP
Choose priorities of VIP and DSCP.
3. enable both TOS and DSCP
Choose "DSCP".
4. enable both VIP and DSCP

4-2. Commands of CLI
To see the commands of the mode, please input “?” after the prompt, then all
commands will be listed in the screen. All commands can be divided into two
categories, including global commands and local commands. Global commands can
be used wherever the mode you are. They are “exit”, “end”, “help”, “history”, “logout”,
“save start”, “save user”, “restore default” and “restore user”. For more details,
please refer to Section 4-2-1.
Command instructions reside in the corresponding modes are local commands.
The same command with the same command name may occur but perform totally
different function in different modes. For example, “show” in IP mode performs
displaying the IP information; however, it performs displaying the system information
in system mode. For more details, please refer to Section 4-2-2.

5. Maintenance
5-1. Resolving No Link Condition
The possible causes for a no link LED status are as follows:
ꢀ
ꢀ
ꢀ
ꢀ
The attached device is not powered on
The cable may not be the correct type or is faulty
The installed building premise cable is faulty
The port may be faulty
5-2. Q&A
1. Computer A can connect to Computer B, but cannot connect to Computer C
through the Managed Switch.
ꢀ
The network device of Computer C may fail to work. Please check the
link/act status of Computer C on the LED indicator. Try another network
device on this connection.
ꢀ
The network configuration of Computer C may be something wrong. Please
verify the network configuration on Computer C.
2. The uplink connection function fails to work.
ꢀ
The connection ports on another must be connection ports. Please check if
connection ports are used on that Managed Switch.
Please check the uplink setup of the Managed Switch to verify the uplink
function is enabled.
ꢀ
3. The console interface cannot appear on the console port connection.
ꢀ
The COM port default parameters are [Baud Rate: 57600, Data Bits: 8,
Parity Bits: None, Stop Bit: A, Flow Control: None]. Please check the COM
port property in the terminal program. And if the parameters are changed,
please set the COM configuration to the new setting.
ꢀ
ꢀ
Check the RS-232 cable is connected well on the console port of the
Managed Switch and COM port of PC.
Check if the COM of the PC is enabled.
4. How to configure the Managed Switch?
ꢀ
The “Hyperterm” is the terminal program in Win95/98/NT. Users can also use
any other terminal programs in Linux/Unix to configure the Managed Switch.
Please refer to the user guide of that terminal program. But the COM port
parameters (baud rate/ data bits/ parity bits/ flow control) must be the same
as the setting of the console port of the Managed Switch.
