RS-232 Console  
This Console port is used to connect a management station or  
terminal with the switch. Out-of-band management means go  
through the RS-232 port. For more information about switch  
management, see Section 4 “ Connecting to the Network ”.  
Software Concepts  
Static Address  
This feature allows you to enter the addresses that will not be aged  
out. It can confine users on certain ports specified by the system  
manager, so that they cannot switch to other ports.  
Spanning Tree  
Spanning Tree Protocol (STP) is an industry standard that prevents  
loops configurations in switched networks. The Spanning Tree  
algorithm creates a single path through network by making sure that  
if more than one path exists between parts of a network, only one of  
those paths is used.  
This also permits multiple interswitch links to remain active for data  
transport while operating in conjunction with the Spanning Tree  
algorithm. The IEEE 802.1d Spanning Tree Protocol support for  
redundant backbone connections and loop-free networks simplifies  
network configuration and improves fault tolerance.

Virtual LANs ( VLANs )  
A VLAN is a group of switch ports designated by the switch as  
belonging to the same broadcast domain.  
This feature allows workgroups to be defined on the basis of their  
logical function instead of their physical location, and does not  
require recabling. It also enables you to configure port-based VLANs  
to help isolate broad- cast traffic and increase security, so as to  
increase bandwidth to each station.  
VLAN also helps you create limited broadcast domains, to prevent  
traffic from being forwarded to stations where it is not needed.  
Port Trunking  
Port Trunking allows you to build higher bandwidth connections by  
aggregate several ports into one single group.  
Additionally, it may be more cost-effective to trunk multiple lower  
speed links than to underutilize a gigabit port. Available copper links  
and supported distances are more pervasive for lower speed links.  
For example, 100Mbps NICs and switch ports are less expensive  
than 1Gbps equipment.  
Port trunking also allows end users to protect their investment in  
existing infrastructure by reusing current equipment.  
SNMP  
( Simple Network Management Protocol ) A widely-used network  
monitoring and control protocol. Data is passed from SNMP agents,  
which are hardware and/or software processes reporting activity in  
each network device ( hub, router, bridge, etc. ) to the workstation  
console used to oversee the network. The agents return information  
contained in a MIB ( Management Information Base ), which is a  
data structure that defines what is obtainable from the device and  
what can be controlled ( turned off, on, etc.). Originating in the UNIX  
community, SNMP has become widely used on all major platforms.

Port Mirror  
Port mirror allows user to define a destination port and a target port ,  
all the packet on the target port will be copy and resend to  
destination port, it make user can monitor the packet and won’t  
effect the bandwidth of target port.  
IGMP  
Internet Group Multicast Protocol (IGMP) is used to support  
real-time applications such as video conferencing or streaming  
audio. IGMP allow you to query for any attached hosts who want to  
receive a specific multicast service. The switch looks up the IP  
Multicast Group used for this service and adds any port which  
received a similar request to that group. It then propagates the  
service request on to any neighboring multicast switch to ensure  
that it will continue to receive the multicast service.  
Port Security  
Port Security allow you to restrict specific MAC addresses to reside  
in some port. The mean is only packet that with pre-defined MAC  
address will be received by the port. It allows user by manual input  
the MAC address table.  
Priority  
There are two priority queues ( high and low ) on each port. Each  
port arbitrates between two transmit queues ( high and low priority ).  
The arbitration uses weighted round-robin between the high and low  
priority queues, and you can adjust this weight.  
Broadcast Storm Filter  
Storm Filter can avoid any flooded data packets. This feature  
prevents the bursts of broadcast traffic. Excessive broadcast  
packets ( Broadcast Storms ) can be filtered in our managed switch  
by enabling the "Broadcast Storm Filtering" option.

Network Configuration  
This chapter provides 3 network configuration examples by using  
the Modular Switch:  
Collapsed Backbone Application  
Departmental Bridge Application  
Virtual LAN (VLAN) Application  
The switch provides versatile configuration options for the network. It  
is ideally suited as a workgroup or segment switch in a network; it  
aggregate traffic from workgroup switches, or provide dedicated  
100Mbps to servers with bandwidth-intensive applications. And  
because all Fast Ethernet ports auto-negotiate for operation at 100  
Mbps or 1000Mbps ( Gigabit ) the switch is perfectly suited to an  
evolving network environment where demand for network speed is  
increasing.  
Collapsed Backbone Application  
For small network where substantial growth can be expected in the  
near future, this switch is an ideal solution supporting backbone  
connectivity.  
The switch can be used as a standalone switch for a group of heavy  
traffic users. Switching is brought to the desktop either through a  
single end-station per switch port or through a multi-port hub.  
A 100 Mbps server is connected to a port, providing end stations  
high-speed accessibility to its applications. This configuration  
provides dedicated 100 Mbps connections to the network center, to  
the server, and the most up to 24 users.

When the network needs expansion, you can simply daisy-chain the  
switch to any IEEE 802.3 ( Ethernet ), IEEE 802.3u ( Fast Ethernet ),  
IEEE 802.3z ( Gigabit Ethernet ) compliant hub. This switch can also  
cooperate with a wide range of networking devices (e.g., firewall  
routers and printer servers) added to the network.  
Figure 3-1. Collapsed Backbone Application  
Departmental Bridge  
For enterprise networks where large data broadcasts are constantly  
processed, this switch is an ideal solution for department users to  
connect to the corporate backbone. The Modular Switch used as  
segment switch can alleviate user contention for bandwidth and  
eliminate server and network bottlenecks. All ports can connect to  
high-speed department servers that need high bandwidth. This  
switch provides parallel communications between each of its ports,  
which can run up to 200 or 2000Mbps at full duplex.  
The Switch makes key servers available to more users by allowing  
multiple conversations to occur concurrently, thereby significantly  
expanding overall network throughput. Moreover, this switch eases  
supervision and maintenance by allowing network manager  
centralize multiple servers in a single location.

Figure 3-2. Departmental Bridge Application  
NOTE: Full-duplex operation only applies to point-to-point access  
(for example, when attaching the switch to a workstation, server, or  
another switch). When connecting to hubs, use a standard cascaded  
connection set for half-duplex operation.

IEEE 802.1Q VLAN Application  
The switch support up to 4095 port-based 802.1Q-compatible virtual  
LANs (VLANs).  
Port-based VLAN Workgroup  
You can group the switch ports into broadcast domains by assigning  
them to the same VLAN to increase network capacity and  
performance. With network segmentation, each switch port connects  
to a segment that is a single broadcast domain. Packets received in  
one VLAN can only be forwarded within that VLAN.  
VLAN allows the grouping of end stations logically, based not on  
physical location but on business policies such as job function or  
department. Members of a group can be dispersed throughout a  
facility - they do not have to be connected in close physical  
locations.  
Hence, group members can coordinate their data communication  
requirements regardless of the actual working locations; and the  
logical network can extend to any point you want it to. Moreover,  
VLAN groups can be modified at any time to add, move or change  
users without any re-cabling.

Shared Server  
The switch compliant to the IEEE802.1Q tagging VLAN standard  
allows ports to exist in multiple VLANs for shared resources, such as  
servers, printers, and switch-to-switch connections. It is also  
possible to have resources exist in multiple VLANs on one switch as  
shown in the following figure.  
Figure 3-4. Shared Server  
In this example, stations on different VLANs share resources. As a result,  
VLAN 1 and VLAN 2 can access VLAN 3 for printing. The broadcasts  
from ports configured in VLAN3 can be seen by all VLAN port members  
of VLAN3.

VLAN ( Virtual LAN )  
A port-based VLAN is a group of switch ports designated by the  
switch as belonging to the same broadcast domain. If a broadcast  
packet is received from a port, it will forward this broadcast packet  
only to those ports belonging to the same VLAN. VLAN classification  
of every packet is done in the following way: If the packet is tagged  
with non-zero VLAN-id field then this is used as the VLAN id.  
Otherwise the default VLAN id of the input port is used. You can  
assign a single switch port to two or more VLANs. The factory  
default VLAN is that all ports belong to the same VLAN group 1.  
Creating VLANs increases network flexibility by allowing you to  
reassign devices to accommodate network moves, additions, and  
changes, eliminating the need to change physical cabling.  
The switch support up to 4095 port-based 802.1Q-compatible virtual  
LANs (VLANs).

finally press "Apply" button only once to configure the desired  
VLANs you want.  
Note: if you want to set multiple VLANs, we suggest that you set  
Default VLAN ID for each port first in Ports page.  
Trunk  
Port trunking is the ability to group several 10/100Base-TX or  
100Base-FX ports to increase the bandwidth between this switch  
and another compatible switch. This is an inexpensive way to  
increase bandwidth. We define port trunking as the ability to group  
set of ports (up to 8) within the same module into a single logical link.  
The port trunk acts as a single link between switches. Multiple trunks  
may be implemented in this switch, but only one trunk can be  
created within a module.

( Note: Make sure trunking ports are in the same VLAN group. )  
STP (Spanning Tree Protocol)  
Spanning tree is a link management protocol that provides path  
redundancy while preventing undesirable loops in the network. For Layer  
2 Ethernet network to function properly, only one active path must exist  
between two stations. The spanning-tree algorithm calculates the best  
loop-free path throughout a switched network. STP forces redundant  
data paths into a standby (blocked) state. If a network segment in the  
spanning tree fails and a redundant path exists, the spanning-tree  
algorithm recalculates the spanning tree topology and activates the  
standby path.

Port Security  
Port Security allow you to restrict specific MAC addresses to reside  
in some port. For example, a dummy hub is attached to some port  
for extension, and you just only allow 2 users to access this port at  
the same time, you can use the port security window to set the  
parameters.  
Figure 5-9. The Port Security page  
To restrict the number of MAC address to reside in a port, you must  
do the following :  
Click the “ Enable “ checkbox for that port. IF the “ Enable  
“checkbox is uncheck, there is no MAC address count restriction  
for that port.  
Type the number in the “ Max Allowed MAC Address Count  
“ edit for that port. The upper bound of this number is the “ Max  
Allowed MAC Address Count per port “  
Press the “ Press “ button  
The “ Used Count “ will tell you how many MAC address residing  
in the corresponding port now.

option.  
Priority  
There are two priority queues ( high and low ) on each port. Each  
port arbitrates between two transmit queues ( high and low priority ).  
The arbitration uses weighted round-robin between the high and low  
priority queues, and you can adjust this weight.  
Programmable Mapping of 802.1p to Internal Priority  
The received packets with 802.1q tag are assigned priority  
according to a flexible (fixed for the old 48310 and 48320 module)  
and programmable mapping of the 802.1p user-priority tag (3 bits,  
value from 0 to 7) to the internal priority queue. The default is to  
assign a packet to high priority queue when the 802.1p user-priority  
tag is 4 to 7, and to low priority queue when the 802.1p user-priority  
tag is 0 to 3. Please check the corresponding mapping checkbox to  
assign a high priority or uncheck that to assign a low priority.

Priority 2  
Each port can parse the header of an incoming IPv4 header and  
identify the Type-Of-Service byte (TOS field). This is extremely  
important with the deployment of Microsoft Windows 2000 and the  
emerging DiffServ standard, which marks Voice-Over-IP and other  
real-time traffic using this field. This feature provides Quality of  
Service (QoS).  
IF this function of a port is enabled, then the most significant 6 bits of  
the TOS (these 6 bits are also known as the DiffServ Code Point  
"DSCP" field, value from 0 to 63) are used to assign a priority to the  
packet received from this port. Please check the corresponding  
mapping checkbox to assign a high priority or uncheck that to assign  
a low priority. The old 48310 and 48320 modules do not support this  
function.

IGMP (IP Multicast)  
IGMP is used in multicast communication network applications  
where one or more servers, for example, video servers, generate  
multicast traffic. If you want your switch to support multimedia and IP  
multicast, enable this option (default is enabled). When this option is  
enabled, this switch only directs the multicast data packets to the  
ports where needed, saving bandwidth. If "Forward with high  
priority" option is enabled, then the IP multicast traffic will have a  
higher priority than other traffic.

Static Address  
You can lock a certain MAC address ( associated with a host, ) to a  
certain port. Once a certain MAC address is locked to a certain port,  
this MAC address will not receive any packets if it is moved to  
another port.  
Static addresses are manually entered into the Static Address Table.  
1. Enter the MAC address in the MAC Address field (ex.  
00-11-22-33-44-55).  
2. Select the Module and Port you want to associate with this entry  
with from the Port drop-down box.

Broadcast Storm Filter  
Excessive broadcast packets (broadcast storms) can be filtered in  
our managed switch by enabling the "Broadcast Storm Filtering"  
option.  
When this option is enabled, if more than 3000 packets per second  
broadcast packets sent to a port lasts 5 seconds, this port will not  
receive any broadcast packets until less than 3000 packets per  
second broadcast packets received lasts 5 seconds. If a broadcast  
storm happens to a port, you will see a red "BS" text appearing in the  
corresponding (module, port) cell, otherwise a "-" text.

SNMP Management  
This section describes how to configure and manage the switch by  
accessing Management Information Base (MIB) objects with the  
SNMP protocol.  
56  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SNMP Management  
The switch MIB options are accessible through SNMP. Instead of  
defining a large set of commands, SNMP performs all operations  
using the “GET”, “GETNEXT” and “SET” commands. The SNMP  
agent that resides on the switch can respond to MIB-related queries  
being sent by the network management software.  
The SNMP agent gathers data from the MIB, which keeps  
information about device parameters and network data. The agent  
can send traps, or notification of certain events, to the manager.  
Figure 6-1: SNMP Network  
The SNMP manager uses information in the MIB to perform the  
operations described below:

Afterwards, you click to select Port 4 and Port 5 for the purpose of  
overlapping. Remember to click “ Apply “ button after you finish  
your setting.  
Now you have create two VLAN Groups ( Group1 VID=1 and  
Group2 VID=2 ) with overlapping ports ( Port 4 & Port 5 ).  
Tagging ( Mac Address based ) VLAN  
This method of tagging is defined in the IEEE 802.1Q standard, to  
configure switch port by the tagging function that allows the port to  
transmit tagging frame. VLAN Tagging can only be used if the  
devices at both ends of a link support IEEE 802.1Q.  
The following example show you how to create 3 VLAN Groups with  
one common tagged port.
