4.4 Port Mirroring

This function provide to monitoring network traffic that forwards a copy of each incoming or outgoing packet from one port

of a network Switch to another port where the packet can be studied. It enables the manager to keep close track of switch

performance and alter it if necessary. The Port Mirroring screen in Figure 4-5 appears.

Figure 4-5 Mirror Setting screen

The page includes the following configurable data:

• Destination Port

• Sour ce Po rt

Configuring the port mirroring by assigning a source port from which to copy all packets and a destination port where those

packets will be sent.

#Note:

With the Chipset specification – the GSW-1602SF/2404SF port mirroring support RX (receive) mode only - this mode will duplicate the data that send to the source and forward to the destination

port.

Use this option to select the port for monitored traffic. This is the port that your network analyzer would be connected to – such as NAI Sniffer Pro or Ethereal.

Duplicate the data transmitted from the source port and forward it to the Destination port.

4.5 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/2404SF switch supports 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.

4.5.2 Per Port Configuration

The VLAN Per Port Configuration page contains fields for managing ports that are part of a VLAN. The port default VLAN

ID (PVID) is configured on the VLAN Port Configuration page. All untagged packets arriving to the device are tagged by

the ports PVID. The screen in Figure 4-10 appears.

The page includes the following fields:

Figure 4-10 VLAN Port Configuration

• VLAN Type -

• Port -

• Link Type -

• Ingress Filtering

Enable-

There’re two VLAN mode support – 802.1Q VLAN and Port-Bas VLAN

• 802.1Q – Packets income will be tagged with VID as the PVID setting. All ports

on the switch belong to default VLAN (VID 1).

• Port-Base - Packets can only be broadcast among other members of the

same VLAN group. Note all unselected ports are treated as belonging to the default system VLAN.

If port-based VLAN are enabled, then VLAN-tagging feature is ignored.

Select the physical interface for which you want to display or configure data.

Allow 802.1Q Untagged or Tagged VLAN for selected port.

When adding a VLAN to selected port, it tells the switch whether to keep or remove the tag from a frame on egress.

• Untag: outgoing frames without VLAN-Tagged.

• Tagged: outgoing frames with VLAN-Tagged.

Enabled - the frame is discarded if this port is not a member of the VLAN with

which this frame is associated. In a tagged frame, the VLAN is identified by the VLAN ID in the tag. In an untagged frame, the VLAN is the Port VLAN ID specified for the port that received this frame.

Disabled - all frames are forwarded in accordance with the 802.1Q VLAN bridge

specification. The factory default is disabled.

• Acceptable Frame Types -

• PVID -

Specifies the types of frames that may be received on this port. The options are 'All' and 'Tagged only'.

• All- untagged frames or priority tagged frames received on this port are

accepted and assigned the value of the Port VLAN ID for this port.

• Tagged only - untagged frames or priority tagged frames received on this port

are discarded.

With either option, VLAN tagged frames are forwarded in accordance to the

802.1Q VLAN specification.

Allow assign PVID for selected port. The range for the PVID is 1-4094

The PVID will be inserted into all untagged frames entering the ingress port. The

PVID must as same as the VLAN ID that the port belong to VLAN group, or the untagged traffic will be dropped.

4.5.3 VLAN setting example:

4.5.3.1 Two separate 802.1Q VLAN

The diagram shows how the switch handle Tagged and Untagged traffic flow for two VLANs. VLAN Group 2 and VLAN

Group 3 are separated VLAN. Each VLAN isolate network traffic so only members of the VLAN receive traffic from the

same VLAN members. The screen in Figure 4-11 appears and Table 4-1 describes the port configuration of switch.

Figure 4-11 two separate VLAN diagram

VLAN Group VID Untagged Members Tagged Members

VLAN Group 1 1 Port-7~Port-24 N/A

VLAN Group 2 2 Port-1,Port-2 Port-3

VLAN Group 3 3 Port-4,Port-5 Port-6

Table 4-1 VLAN and Port Configuration

The scenario described as follow:

 Untagged packet entering VALN 2

1. While [PC-1] transmit an untagged packet enters Port-1, the switch will tag it with a VLAN Tag=2. [PC-2] and

[PC-3] will received the packet through Port-2 and Port-3.

2. [PC-4],[PC-5] and [PC-6] received no packet.

3. While the packet leaves Port-2, it will be stripped away it tag becoming an untagged packet.

4. While the packet leaves Port-3, it will keep as a tagged packet with VLAN Tag=2.

 Tagged packet entering VLAN 2

5. While [PC-3] transmit a tagged packet with VLAN Tag=2 enters Port-3, [PC-1] and [PC-2] will received the

packet through Port-1 and Port-2.

6. While the packet leaves Port-1 and Port-2, it will be stripped away it tag becoming an untagged packet.

 Untagged packet entering VLAN 3

1. While [PC-4] transmit an untagged packet enters Port-4, the switch will tag it with a VLAN Tag=3. [PC-5] and [PC-6] will received the packet through Port-5 and Port-6.

2. While the packet leaves Port-5, it will be stripped away it tag becoming an untagged packet.

3. While the packet leaves Port-6, it will keep as a tagged packet with VLAN Tag=3.

#Note:

Setup steps

1. Create VLAN Group

Set VALN Group 1 = default-VLAN with VID (VLAN ID)=1

Add two VLANs – VLAN 2 and VLAN 3

VLAN Group 2 with VID=2 VLAN Group 3 with VID=3

At this example, VLAN Group 1 just set as default VLAN, but only focus on VLAN 2 and VLAN 3 traffic flow

2. Assign VLAN Member :

VLAN 2 : Port-1,Port-2 and Port-3 VLAN 3 : Port-4, Port-5 and Port-6 VLAN 1 : All other ports – Port-7~Port-24

Figure 4-12 Add new VLAN Group screen

Figure 4-13 Assign VLAN members for VLAN 2 and VLAN 3

Remember to remove the Port 1 – Port 6 from VLAN 1 membership, since the Port 1 – Port 6 had be assigned to

VLAN 2 and VLAN 3.

#Note:

Figure 4-14 Remove specify ports from VLAN 1 member

It’s import to remove the VLAN members from VLAN 1 configuration. Or the ports would become overlap setting. ( About the overlapped VLAN configuration, see next VLAN configure sample)

3. Assign PVID for each port:

Port-1,Port-2 and Port-3 : PVID=2 Port-4,Port-5 and Port-6 : PVID=3 Port-7~Port-24 : PVID=1

4. Enable VLAN Tag for spe c if i c po rt s

4.5.3.2 Two VLANs with overlap area

Follow the example of 4.5.3.1. There’re two exist separate VLANs – VLAN 2 and VLAN 3, and the PCs of each VLANs are

not able to access each other of different VLANs. But they all need to access with the same server. The screen in Figure

4-16 appear. This section will show you how to configure the port for the server – that could be accessed by both VLAN 2

and VLAN 3.

Figure 4-16 A Server connect to the VLAN overlap area

1. Specify Port-7 on the device to connect to the server.

2. Assign Port-7 to both VLAN 2 and VLAN 3 at the VLAN Member configuration page. The screen in Figure 4-17

appears.

Figure 4-17 VLAN overlap port setting

3. Define a VLAN 1 as a “Public Area” that overlapping with both VLAN 2 members and VLAN 3 members.

4. Setup Port-7 with “PVID=1” at VLAN Per Port Configuration page. The screen in Figure 4-19 appears.

Figure 4-19 Setup Port-7 with PVID-1

That is, although the VLAN 2 members: Port-1 to Port-3 and VLAN 3 members: Port-4 to Port-6 also belong to VLAN 1.

But with different PVID settings, packets form VLAN 2 or VLAN 3 is not able to access to the other VLAN.

4.5.3.3 VLAN Trunking between two 802.1Q aware switch

The most cases are used for “Uplink” to other switches. VLANs are separated at different switches, but they need to

access with other switches within the same VLAN group. The screen in Figure-20 appears.

Figure 4-20 802.1Q Trunking with other VLAN aware device

About the VLAN ports connect to the hosts, please refer to 4.5.3.1 and 4.5.3.2 examples. The following steps will focus on

the VLAN Trunk port configuration.

1. Specify Port-8 to be the 802.1Q VLAN Trunk port, and the Trunking port must be a Tagged port while egress. The

Port-8 configuration as the following screen in Figure 4-21.

Figure 4-21 The configuration of VLAN Trunk port

2. Assign the VLAN Trunk Port to be the member of each VLAN – which wants to be aggregated. At this sample, add

Port-8 to be VLAN 2 and VLAN 3 member port.

Figure 4-22 Add VLAN Trunk port to each VLAN

3. Repeat Step 1 and 2, setup the VLAN Trunk port at the partner switch.

4. To add more VLANs to join the VLAN trunk, repeat Step 2 to assign the Trunk port to the VLANs.

4.6 Rapid Spanning

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.

#Note:

This page is to enable/disable the Spanning Tree protocol. The switch support IEEE 802.1d Spanning Tree (STP), IEEE

802.1w Rapid Spanning Tree (RSTP). The screen in Figure 4-23 appears.

The GSW-1602SF/GSW-2404SF 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.

• Blocking -- The port is currently blocked and cannot be used to forward traffic

or learn MAC addresses. Blocking is displayed when Classic STP is enabled.

• Listening -- The port is currently in the listening mode. The port cannot forward

traffic nor can it learn MAC addresses.

• Learning -- The port is currently in the learning mode. The port cannot forward

traffic however it can learn new MAC addresses.

• Forw arding -- The port is currently in the forwarding mode. The port can

forward traffic and learn new MAC addresses.

#Note:

A port transitions fro m one state to another as follows:

• From initialization (switch boot) to blocking

• From blocking to listening or to disabled

• From listening to learning or to disabled

• From learning to forwarding or to disabled

• From forwarding to disabled

• From disabled to blocking

4.7 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.

4.7.1 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).

 Eight Trunk Group per system

 For GSW-1602SF, up to 8 ports per Trunk Group

 For GSW-2404SF, up to 12 ports per Trunk Group

The Port Trunking configuration screen in Figure 4-29 appears.

Figure 4-29 Aggregation/Trunking Configuration screen

The page includes the following fields:

• Port

• Normal

• Group

Indicate port 1 to port 24.

While a port be checked as “Normal”, the port is not join to any Static Trunk Group.

Specify the Joined Trunk Group. There’re maximum eight trunk groups per system. With different switch model, the maximum number of ports are as follow:

GSW-1602SF – Up to 8 ports per Trunk Group GSW-2404SF – Up to 12 ports per Trunk Group

A port can be assigned to only one Trunk Group.

4.7.2 LACP

Link Aggregation Control Protocol (LACP) - 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.

The LACP Port Configuration page contains fields for assigning LACP properties to individual ports. The screen in Figure

4-30 appears.

The page includes the following fields:

• Port

• Protocol Enable

• Key Va lu e

Indicate port 1 to port 24.

To Enable or disable the LCAP protocol on a selected port. Once the LACP protocol be enabled, the system will start transmit the LACP control packets and exchange with another LACP aware switch. If the linked switch didn’t support LACP, then the aggregated link will not be established.

The Key Value will be filed in the LACP control packets. Ports with same key value will be set to the same LACP Group. If two ports are set with different key value, they will become two different LCAP groups. The key value will also be the identify ID to the linked LACP switch.

Figure 4-30 LACP Port Configuration

The default setting is “Auto”

"Note:

When using a port link aggregation, note that:

• 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.

4.8 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.

4.8.1 IGMP Snooping Configuration

The IGMP Configuration page let the administrator to configure the parameters for IGMP Snooping, which is used to build

forwarding lists for multicast traffic. The screen in Figure 4-34 appears.

Figure 4-34 IGMP Snooping Configuration and Status

The page includes the following fields:

• IGMP Enable

• Router Ports

• Unregistered IPMC

Flooding Enable

• VLAN ID

• IGMP Snooping

Enabled

Enables or disables IGMP global function on the device.

Disabled is the default value.

The Router Ports check box fields for attaching ports to a device that is attached to a neighboring Multicast router/switch. Once IGMP Snooping is enabled, Multicast packets are forwarded to the appropriate port .

The function is to set “Enable” or “Disable” to allow the unregistered IP Multicast Group streams to flood to all ports of this switch. The unregistered IP Multicast means that the received Multicast Group address not listed in the Multicast Group Table of the switch.

Enabled is the default value. The switch forwards all the multicast steams to all

the host or linked switch.

Identifies a VLAN and contains information about the Multicast group configuration. Add a new VLAN group and the Table will add the VLAN entry automatically.

Enables or disables IGMP snooping on the VLAN. Ports be assign to the VLAN will be applied to filter the Multicast stream.

Enabled is the default value.

• 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.

Add a new VLAN group, the VLAN ID will be added to the table automatically with both “IGMP

4.9 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.

"Note:

The QoS Configuration page in Figure 4-37 appears.

The current version of GSW-1602SF/2404SF support QoS Strict mode only. The strict mode is to

specifies if traffic scheduling is based strictly on the queue priority.

Figure 4-37 QoS Configuration screen

4.9.1 802.1p QoS Mode

QoS settings allow customization of packet priority in order to facilitate delivery of data traffic that might be affected by

latency problems. The IEEE 802.1p Priority specification uses 8 priority levels to classify data packets. The screen in

Figure 4-38 and Figure 4-39 appears.

4.9.2 DSCP QoS Mode

DiffServ Code Point (DSCP) － is the traffic prioritization bits within an IP header that are encoded by certain applications

and/or devices to indicate the level of service required by the packet across a network.

The DSCP Configuration page provides fields for defining output queue to specific DSCP fields.

Select the QoS mode to DSCP, the DSCP to queue mapping configuration page appears, as the Figure 4-40 shows.

4.10 802.1X Management

The PALENT GSW-1602SF/2404SF 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): 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 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 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 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.

9. The RADIUS server sends Web-Smart Switch a RADIUS ACCEPT message.

10. Web-Smart Switch sends the client an EAP Success message along with the broadcast key and key length.

This section is to control the access of the switch, includes the user access and management control. The 802.1X

Management page contains links to the following topics:

• RADIUS Server Configuration

4.13.6 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

screen in Figure 4-59 appears.

Figure 4-59 Cable Diagnostics

The Cable Diagnostics includes the following fields:

• Port

• Mode

Specifies the port numbers for which to run the cable diagnostics.

There’re three cable test mode for selection:

Full – test full pairs Anomaly – test with only anomaly pairs Anomaly w/o X-pair - test anomaly pairs but without X-pair

The Cable status includes the following items:

• Pair

• Length[m]

• Status

The twist pair of the UTP cable. The pair groups as follow:

A (Pin 1,2) B (Pin 3,6) C (Pin 4,5) D (Pin 7,8)

When properly terminated, Cable Diagnostics reports the approximate cable length in meters of each of the four cable pair A, B, C, and D.

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 a 100

Ω 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.

"Note:

Be sure to running the Cable diagnostics with standard Cat 5e or Cat 6 UTP cable. With some of the UTP cables that not match the standard of Cat 5e, it might cause the 10/100Base link down after the cable diagnostics.

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. Thereby 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

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.

Checksum

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.

The states a computer will go through to join or to leave a multicast group are shown below:

7. 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 irreg u lar

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.
