4.6 VLANs
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic
so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network
devices are still plug into the same switch physically.
The GSW-1602SF/GSW-2404SF/GSW-2416SF switch supports IEEE 802.1Q (tagged-based) and Port-Base VLAN
setting in web management page. In the default configuration, VLAN support is “802.1Q”.
Port-based VLAN
Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of
the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire
department.
On port-based VLAN.NIC do not need to be able to identify 802.1Q tags in packet headers. NIC send and receive normal
Ethernet packets. If the packet's destination lies on the same segment, communications take place using normal Ethernet
protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN
considerations come into play to decide if the packet is dropped by the Switch or delivered.
IEEE 802.1Q VLANs
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which enables them to span
the entire network (assuming all switches on the network are IEEE 802.1Q-compliant).
VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will
only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes
broadcast, multicast and unicast packets from unknown sources.
VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN will only deliver packets between stations
that are members of the VLAN. Any port can be configured as either tagging or untagging. The untagging feature of IEEE
802.1Q VLAN allows VLAN to work with legacy switches that don't recognize VLAN tags in packet headers. The tagging
feature allows VLAN to span multiple 802.1Q-compliant switches through a single physical connection and allows
Spanning Tree to be enabled on all ports and work normally.

4.7 Rapid Spanning Tree
Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path
between end stations on a network, eliminating loops.
Rapid Spanning Tree Protocol (RSTP) - While Classic Spanning Tree guarantees preventing L2 forwarding loops in a
general network topology, convergence can take up to 30-60 seconds. The convergence time is considered too long for
many applications. When network topology allows, faster convergence may be possible. The Rapid Spanning Tree
Protocol (RSTP) detects and uses of network topologies that provide faster convergence of the spanning tree, without
creating forwarding loops.
The devices support the following Spanning Tree protocols:
‧ Compatiable -- Spanning Tree Protocol (STP):Provides a single path between end stations, avoiding and
eliminating loops.
‧ Normal -- Rapid Spanning Tree Protocol (RSTP) : Detects and uses of network topologies that provide
faster spanning tree convergence, without creating forwarding loops.
The GSW-1602SF/GSW-2404SF/GSW-2416SF implement the Rapid Spanning Protocol as the
default spanning tree protocol. While select “Compatibles” mode, the system use the RSTP
(802.1w) to compatible and co work with another STP (802.1d)’s BPDU control packets.
#Note:
This page is to enable/disable the Spanning Tree protocol. These Switch support IEEE 802.1d Spanning Tree (STP),

4.8 Link Aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups
(LAGs). Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link
redundancy.
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media
types (UTP/Fiber, or different fiber types), provided they operate at the same speed.
Aggregated Links can be assigned manually (Port Trunk) or automatically by enabling Link Aggregation Control Protocol
(LACP) on the relevant links.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port
attributes to a non-aggregated port, including auto-negotiation, speed, Duplex setting, etc.
The device supports the following Aggregation links :
„
„
Static LAGs (Port Trunk) – Force aggregared selected ports to be a trounk group.
Link Aggregation Control Protocol (LACP) LAGs - LACP LAG negotiate Aggregated Port links with other
LACP ports located on a different device. If the other device ports are also LACP ports, the devices establish
a LAG between them.
4.8.1 Port Trunk
This function provides to cascade two Switch devices with a double bandwidth (maximum up to 1.6/2.4Gbps in full duplex
mode).

When using a port link aggregation, note that:
"Note:
• The ports that can be assigned to the same link aggregation have certain other restrictions (see
below).
• Ports can only be assigned to one link aggregation.
• The ports at both ends of a connection must be configured as link aggregation ports.
• None of the ports in a link aggregation can be configured as a mirror source port or a mirror
target port.
• All of the ports in a link aggregation have to be treated as a whole when moved from/to, added
or deleted from a VLAN.
• The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.
• Disconnect all link aggregation port cables or disable the link aggregation ports before removing
a port link aggregation to avoid creating a data loop.

4.9 IGMP Snooping
The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups
memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the
CPU for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only
ports that are a member of the multicast group.

• IGMP Querying
Enabled
Enables or disables IGMP Query mode on the VLAN. The Query mode is used to
periodically check the multicast group for members that are no longer active. In
the case where there is more than one multicast router on a sub network, one
router is elected as the ‘queried’. This router then keeps track of the membership
of the multicast groups that have active members. The information received from
IGMP is then used to determine if multicast packets should be forwarded to a
given sub network or not. The router can check, using IGMP, to see if there is at
least one member of a multicast group on a given subnet work. If there are no
members on a sub network, packets will not be forwarded to that sub network.
Enabled is the default value.

4.10 Quality of Service
Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control over network traffic.
QoS enables you to assign various grades of network service to different types of traffic, such as multi-media, video,
protocol-specific, time critical, and file-backup traffic.
QoS reduces bandwidth limitations, delay, loss, and jitter. It also provides increased reliability for delivery of your data and
allows you to prioritize certain applications across your network. You can define exactly how you want the switch to treat
selected applications and types of traffic.
You can use QoS on your system to:
• Classifying traffic based on packet attributes.
• Assigning priorities to traffic (for example, to set higher priorities to time-critical or business-critical applications).
• Applying security policy through traffic filtering.
• Provide predictable throughput for multimedia applications such as video conferencing or voice over IP by
minimizing delay and jitter.
• Improve performance for specific types of traffic and preserve performance as the amount of traffic grows.
• Reduce the need to constantly add bandwidth to the network.
• Manage network congestion.
The QoS Configuration page contains fields for enabling or disabling QoS. In addition, the 802.1p mode or DSCP mode
can be selected. Both the two mode rely on predefined fields within the packet to determine the output queue.
„
„
„
QoS Disabled - Disables managing network traffic using Quality of Service.
802.1p Mode –The output queue assignment is determined by the IEEE802.1p VLAN priority tag.
DSCP Mode - The output queue assignment is determined by the DSCP field.
The current version of GSW-1602SF/GSW-2404SF/GSW-2416SF support QoS Strict mode only.
The strict mode is to specifies if traffic scheduling is based strictly on the queue priority.

4.11 802.1X Management
The PALENT GSW-1602SF/GSW-2404SF/GSW-2416SF supports IEEE 802.1X Port-base network access control and
RADIUS server authentication to enhance the host link more security. An 802.1X Infrastructure is composed of three
major components: Authenticator, Authentication server, and Supplicant.
Authentication server – (RADIUS Server): An entity that provides an authentication service to an authenticator. This
service determines, from the credentials provided by the supplicant, whether the supplicant is authorized to access the
services provided by the authenticator.
Authenticator-(GSW-1602SF/GSW-2404SF/GSW-2416SF): An entity at one end of a point-to-point LAN segment that
facilitates authentication of the entity attached to the other end of that link.
Supplicant-(A Host Client): An entity at one end of a point-to-point LAN segment that is being authenticated by an
authenticator attached to the other end of that link.
The instructions are divided into three parts:
The above graph shows the network topology of the solution we are going to introduce. As illustrated, a group of clients is
trying to build a network with GSW-1602SF/GSW-2404SF/GSW-2416SF in order to have access to both Internet and
Intranet. With 802.1X authentication, each of these clients would have to be authenticated by RADIUS server. If the client
is authorized, GSW-1602SF/GSW-2404SF/GSW-2416SF would be notified to open up a communication port to be used
for the client. There are 2 Extensive Authentication Protocol (EAP) methods supported: (1) MD5 and (2) TLS.
MD5 authentication is simply a validation of existing user account and password that is stored in a database of RADIUS
server. Therefore, clients will be prompted for account/password validation to build the link. TLS authentication is a more
complicated authentication, which is using certificate that is issued by RADIUS server for authentication. TLS
authentication is a more secure authentication, since not only RADIUS server authenticates the client, but also the client
can validate RADIUS server by the certificate that it issues. The TLS authentication request from clients and reply by
Radius Server and GSW-1602SF/GSW-2404SF/GSW-2416SF can be briefed as follows:
1. The client sends an EAP start message to Web-Smart Switch.
2. Web-Smart Switch replies with an EAP Request ID message.
3. The client sends its Network Access Identifier (NAI) – its user name – to Web-Smart Switch in an EAP Respond
message.
4. Web-Smart Switch forwards the NAI to the RADIUS server with a RADIUS Access Request message.
5. The RADIUS server responds to the client with its digital certificate.
6. The client validates the digital certificate, and replies its own digital certificate to the RADIUS server.
7. The RADIUS server validates client’s digital certificate.
8. The client and RADIUS server derive encryption keys.

4.14.6 Cable Diagnostics
The Cable Diagnostics page contains fields for performing tests on copper cables. These functions have the ability to
identify the cable length and operating conditions, and to isolate a variety of common faults that can occur on the Cat5
twisted-pair cabling. There might be two statuses as follow:
„
If the link is established on the twisted-pair interface in 1000BASE-T mode, the Cable Diagnostics can run without
disruption of the link or of any data transfer.
„
If the link is established in 100BASE-TX or 10BASE-T, the Cable Diagnostics cause the link to drop while the
diagnostics are running.
After the diagnostics are finished, the link is reestablished. And the following functions are available.
• Coupling between cable pairs.
• Cable pair termination
• Cable Length
Anomalous coupling between cable pairs can be caused by shorted wires, improper termination, or high crosstalk
resulting from an incorrect wire map. These conditions can all prevent the PLANET switch from establishing a link. The

• Status
The cable test results. Possible values are:
• Proper - The cable passed the test.
• Open - The cable is connected on only one side or there is no cable connected
to the port
• Short - A short has occurred in the cable. With 10/100BASE link, the status of
Pair C and Pair D will be “Short”.
• Abnormal termination – An improper termination be detected. Proper
termination of Cat5 cable requires 100Ω differential impedance between
the positive and negative cable terminals. IEEE STD 802.3 allows for a
termination of as large as 115Ω or as small as 85Ω. If the termination
falls out of this range, it is reported as falls an anomalous termination.

5. SWITCH OPERATION
5.1 Address Table
The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to
store the address information of some node in network, including MAC address, port no, etc. This information comes from
the learning process of Ethernet Switch.
5.2 Learning
When one packet comes in from any port, the Switch will record the source address, port no. And the other related
information in address table. This information will be used to decide either forwarding or filtering for future packets.
5.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address besides the
source address learning. The Ethernet Switching will lookup the address-table for the destination address. If not found,
this packet will be forwarded to all the other ports except the port, which this packet comes in. And these ports will transmit
this packet to the network it connected. If found, and the destination address is located at different port from this packet
comes in, the Ethernet Switching will forward this packet to the port where this destination address is located according to
the information from address table. But, if the destination address is located at the same port with this packet comes in,
then this packet will be filtered. There by increasing the network throughput and availability.
5.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-Forward Ethernet Switching stores the
incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets
occurrence, it is the best choice when a network needs efficiency and stability.
The Ethernet Switch scans the destination address from the packet-header, searches the routing table provided for the
incoming port and forwards the packet, only if required. The fast forwarding makes the switch attractive for connecting
servers directly to the network, thereby increasing throughput and availability. However, the switch is most commonly
used to segment existing hubs, which nearly always improves overall performance. An Ethernet Switching can be easily
configured in any Ethernet network environment to significantly boost bandwidth using conventional cabling and adapters.
Due to the learning function of the Ethernet switching, the source address and corresponding port number of each
incoming and outgoing packet are stored in a routing table. This information is subsequently used to filter packets whose
destination address is on the same segment as the source address. This confines network traffic to its respective domain,
reducing the overall load on the network.
The Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the re-transmission
rate. No packet loss will occur.
5.5 Auto-Negotiation
The STP ports on the Switch have built-in “Auto-negotiation”. This technology automatically sets the best possible
bandwidth when a connection is established with another network device (usually at Power On or Reset). This is done by
detect the modes and speeds at the second of both device is connected and capable of, both 10Base-T and 100Base-TX
devices can connect with the port in either Half- or Full-Duplex mode. 1000Base-T can be only connected in Full-duplex
mode.

5.6 IGMP Snooping
Theory
Computers and network devices that want to receive multicast transmissions need to inform nearby routers that they will
become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to communicate this
information. IGMP is also used to periodically check the multicast group for members that are no longer active. In the case
where there is more than one multicast router on a sub network, one router is elected as the ‘queried’. This router then
keeps track of the membership of the multicast groups that have active members. The information received from IGMP is
then used to determine if multicast packets should be forwarded to a given sub network or not. The router can check, using
IGMP, to see if there is at least one member of a multicast group on a given subnet work. If there are no members on a sub
network, packets will not be forwarded to that sub network.
IGMP Versions 1 and 2
Multicast groups allow members to join or leave at any time. IGMP provides the method for members and multicast routers
to communicate when joining or leaving a multicast group.
IGMP version 1 is defined in RFC 1112. It has a fixed packet size and no optional data.
The format of an IGMP packet is shown below:
IGMP Message Format
Octets
0
8
16
31
Type
Response Time
Checksum
Group Address (all zeros if this is a query)
The IGMP Type codes are shown below:
Type Meaning
0x11 Membership Query (if Group Address is 0.0.0.0)
0x11 Specific Group Membership Query (if Group Address is Present)
0x16 Membership Report (version 2)
0x17 Leave a Group (version 2)
0x12 Membership Report (version 1)
IGMP packets enable multicast routers to keep track of the membership of multicast groups, on their respective sub
networks. The following outlines what is communicated between a multicast router and a multicast group member using
IGMP.
A host sends an IGMP “report” to join a group
A host will never send a report when it wants to leave a group (for version 1).
A host will send a “leave” report when it wants to leave a group (for version 2).
Multicast routers send IGMP queries (to the all-hosts group address: 224.0.0.1) periodically to see whether any group
members exist on their sub networks. If there is no response from a particular group, the router assumes that there are no
group members on the network.
The Time-to-Live (TTL) field of query messages is set to 1 so that the queries will not be forwarded to other sub networks.
IGMP version 2 introduces some enhancements such as a method to elect a multicast queried for each LAN, an explicit
leave message, and query messages that are specific to a given group.

6. TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Switch is not functioning properly, make sure the
Ethernet Switch was set up according to instructions in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Switch.
Some stations cannot talk to other stations located on the other port
Solution:
Please check the VLAN, port trunking function that may introduce this kind of problem.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is set to full duplex and the partner is set to
half duplex, then the performance will be poor.
100Base-TX port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to
change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
Why the Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the Switch .Try another port on the Switch. Make sure the cable is installed properly
Make sure the cable is the right type Turn off the power. After a while, turn on power again.
