Page 183: Enabling Or Disabling Backpressure
AT-8100 Switch Command Line User’s Guide Enabling or Disabling Backpressure Ports use backpressure during periods of packet congestion, to prevent packet overruns. They use it to stop their link partners from sending any further packets to enable them to process the packets already in their buffers.
Page 184: Enabling Or Disabling Flow Control
Chapter 9: Port Parameters Enabling or Disabling Flow Control When a port that is operating in full-duplex mode needs to temporarily stop its local or remote counterpart from sending any further packets, it initiates flow control by sending what are known as pause packets. Pause packets instruct the link partner to stop sending packets to allow the sender of the packets time to process the packets already stored in its buffers.
Page 185 AT-8100 Switch Command Line User’s Guide This example configures port 21 not to send pause packets during periods of packet congestion: awplus> enable awplus# configure terminal awplus(config)# interface port1.0.21 awplus(config-if)# speed 100 awplus(config-if)# duplex full awplus(config-if)# flowcontrol send off This example enables both the receive and send portions of flow control on port 7: awplus>...

Page 370: Overview
Chapter 19: MAC Address Table Overview The MAC address table stores the MAC addresses of all the network devices that are connected to the switch’s ports. Each entry in the table consists of a MAC address, a port number where an address was learned by the switch, and an ID number of a VLAN where a port is a member.
Page 371 AT-8100 Switch Command Line User’s Guide The period of time the switch waits before purging inactive dynamic MAC addresses is called the aging time. This value is adjustable on the switch. The default value is 300 seconds (5 minutes). You can also enter addresses manually into the table. These addresses are referred to as static addresses.

Page 392: Overview
Chapter 21: Hardware Stacking Overview A stack is a group of two to eight 8100S Series switches that are linked together with the S1 and S2 stacking ports. The switches function as a unified Fast Ethernet switch. They synchronize their actions so that network operations, such as spanning tree protocols, virtual LANs, and static port trunks, span across all of the Fast Ethernet ports.
Page 393 AT-8100 Switch Command Line User’s Guide The second topology, the duplex-ring topology, is identical to the duplex- chain, except that the unused stacking ports on the end switches of the stack are connected together to form a physical loop, creating two pathways through the stack.
Page 394: Active Boot Configuration File
Chapter 21: Hardware Stacking Active Boot The master switch stores the settings of the stack in a file in its file system. This file is called the active boot configuration file. The switch updates the Configuration file with the most recent parameter changes whenever you issue the File WRITE or COPY RUNNING-CONFIG STARTUP-CONFIG command.
Page 395: Initialization Processes
AT-8100 Switch Command Line User’s Guide Here is an example of how the process works. Assume your stack has three switches, assigned the ID numbers 1 to 3. The switch with the ID number 1 is the master switch because it has the lowest ID number of all the switches in the stack.
Page 396: Stacking Actions
Chapter 21: Hardware Stacking This phase may take from just a few seconds to up to a minute, depending on the size of the stack, and the number and complexity of the commands in the file. The switches of the stack begin to forward network traffic at the completion of the fifth phase.
Page 397: Guidelines
AT-8100 Switch Command Line User’s Guide Caution Designating the new member as the new master switch causes the stack to lose its configuration unless the new unit has the same configuration file as the previous master switch.  If the ID number of the new member switch is the same as one of the existing switches in the stack, the new member is automatically assigned the next available ID number.
Page 398 Chapter 21: Hardware Stacking  You have to assign the switches unique stack ID numbers, in the range of 1 to 8, with the STACK command in the Global Configuration mode. You have to assign the numbers before connecting the switches together with the S1 and S2 ports. (A stack in which two or more switches have the same ID number will not function properly.) ...

Page 476: Overview
Chapter 29: DHCP Relay Overview Overview The switch has a DHCP relay agent to relay BOOTP messages between clients and DHCP or BOOTP servers. A client that transmits a request for an IP configuration to a DHCP or BOOTP server has to send the request as a broadcast packet because it does not know the IP address of the server.
Page 477: Dhcp Relay Agent Option 82
AT-8100 Switch Command Line User’s Guide A routing interface that receives a BOOTP reply from a server inspects the broadcast flag field in the packet to determine whether the client, in its original request to the server, set this flag to signal that the response must be sent as a broadcast datagram.

Page 506: Overview
Chapter 31: Group Link Control Overview Group link control is designed to improve the effectiveness of the redundant systems in a network. It enables the switch to alert network devices about problems they might not otherwise detect or respond to, so that they can implement their redundant systems, automatically.
Page 507 AT-8100 Switch Command Line User’s Guide In the first diagram a server with two teamed network adapter cards is connected to different switches, with the active link to switch 3. If there is a failure on the active link, the server can detect it directly and would respond by automatically transferring the traffic to the redundant network interface and the secondary path, which leads to switch 4.
Page 508 Chapter 31: Group Link Control Figure 108. Group Link Control Example 2 With group link control you can address this problem by creating on switch 3 a group of the two ports that connect to switch 1 and the server. Thus, any change to the link state of the port connected to switch 1 is automatically transferred to the port connected to the server.
Page 509 AT-8100 Switch Command Line User’s Guide Figure 109. Group Link Control Example 3 When a link on an upstream port is reestablished, the switch automatically reactivates the downstream counterpart. Referring to the example, when the link on port 17 is reestablished, the switch enables port 24 again. A link control group can have more than one upstream or downstream port.
Page 510 Chapter 31: Group Link Control Figure 110. Group Link Control Example 4 If connectivity is lost on both ports 17 and 20, the downstream ports 24 and 25 are disabled. Figure 111. Group Link Control Example 5 In the previous examples, the ports of the groups on the switch are connected to different devices, making it possible for downstream devices to know whether or not there are links to upstream devices.
Page 511: Table 49. Link Control Groups On Switch 3 In Example 6
AT-8100 Switch Command Line User’s Guide approach is to create groups in which the ports are connected to the same network node. This is useful in network topologies where redundant static port trunks or LACP trunks are controlled by the spanning tree protocol. If a primary trunk loses bandwidth capacity because connectivity is lost on one or more of the links and there is a redundant trunk held in the blocking state by the spanning tree protocol, it may be advantageous to shut down...

Page 594: Overview
Chapter 40: Internet Group Management Protocol (IGMP) Snooping Overview IGMP snooping allows the switch to control the flow of multicast packets from its ports. It enables the switch to forward packets of multicast groups to only ports that have host nodes that want to join the multicast groups. IGMP is used by IPv4 routers to create lists of nodes that are members of multicast groups.
Page 595: Understanding Multicast Traffic Settings
AT-8100 Switch Command Line User’s Guide improves switch performance and network security by restricting the flow of multicast packets to only those switch ports that are connected to host nodes. If the switch is not using IGMP snooping and receives multicast packets, it floods the packets out all its ports, except the port on which it received the packets.
Page 596: Host Node Topology
Chapter 40: Internet Group Management Protocol (IGMP) Snooping Host Node Topology The switch has a host node topology setting. You use this setting to define whether there is more than one host node on each port on the switch. The switch refers to the topology to determine whether or not to continue transmitting multicast packets from ports that receive leave requests or where host nodes time out due to inactivity.
Page 597: Enabling Igmp Snooping
AT-8100 Switch Command Line User’s Guide Enabling IGMP Snooping The command to enable IGMP Snooping on the switch is the IP IGMP SNOOPING command in the Global Configuration mode. After you enter the command, the switch begins to build its multicast table as queries from the multicast router and reports from the host nodes arrive on its ports.

Page 724: Overview
Chapter 49: Static Port Trunks Overview Static port trunks are groups of two to eight ports that act as single virtual links between the switch and other network devices. Static port trunks are commonly used to improve network performance by increasing the available bandwidth between the switch and other network devices and to enhance the reliability of the connections between network devices.
Page 725 AT-8100 Switch Command Line User’s Guide  Source IP Address (Layer 3)  Destination IP Address (Layer 3)  Source IP Address / Destination IP Address (Layer 3) The load distribution methods examine the last three bits of a packet’s MAC or IP address and compare the bits against mappings assigned to the ports in the trunk.
Page 726: Guidelines
Chapter 49: Static Port Trunks For example, assume you selected source and destination MAC addresses for the load distribution method in our previous example, and that a packet for transmission over the trunk had a source MAC address that ended in 9 and a destination address that ended in 3.

Page 742: Overview
Chapter 51: Link Aggregation Control Protocol (LACP) Overview The Link Aggregation Control Protocol (LACP) is used to increase the bandwidth between the switch and other LACP-compatible devices by grouping ports together to form single virtual links. LACP trunks are similar in function to static port trunks, but they are more flexible.
Page 743: Base Port
AT-8100 Switch Command Line User’s Guide Base Port The lowest numbered port in an aggregator is referred to as the base port. You cannot change the base port of an aggregator. You can neither delete it from an aggregator nor add any ports that are below it. For example, if an aggregator consists of ports 5 to 12, you cannot delete port 5 because it is the base port, and you are not allowed to add ports 1 to 4 to the aggregator.
Page 744 The port with the highest priority in an aggregate trunk carries broadcast packets and packets with an unknown destination.  Prior to creating an aggregate trunk between an Allied Telesis device and another vendor’s device, refer to the vendor’s documentation to determine the maximum number of active ports the device supports.
Page 745: Creating New Aggregators
AT-8100 Switch Command Line User’s Guide Creating New Aggregators To create a new aggregator, move to the Port Interface mode of the aggregator’s member ports and issue the CHANNEL-GROUP command, which has this format: id_number channel-group The ID_NUMBER parameter has a range of 1 to 32. Each aggregator must be assigned a unique ID number.
Page 746: Setting The Load Distribution Method
Chapter 51: Link Aggregation Control Protocol (LACP) Setting the Load Distribution Method The load distribution method determines the manner in which the switch distributes the egress packets among the active ports of an aggregator. The packets can be distributed by source MAC or IP address, destination MAC or IP address, or by both source and destination addresses.
Page 747: Adding Ports To Aggregators
AT-8100 Switch Command Line User’s Guide Adding Ports to Aggregators The command to add ports to existing aggregators is the same command to create new aggregators, the CHANNEL-GROUP command in the Port Interface mode.

Page 770: Overview
Chapter 53: STP, RSTP and MSTP Protocols Overview The Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) guard against the formation of loops in an Ethernet network topology. A topology has a loop when two or more nodes can transmit packets to each other over more than one data path.
Page 771: Bridge Priority And The Root Bridge
AT-8100 Switch Command Line User’s Guide Bridge Priority and the Root Bridge The first task that bridges perform when a spanning tree protocol is activated on a network is the selection of a root bridge. A root bridge distributes network topology information to the other network bridges and is used by the other bridges to determine if there are redundant paths in the network.
Page 772: Path Costs And Port Costs
Chapter 53: STP, RSTP and MSTP Protocols Path Costs and Port Costs After the root bridge has been selected, the bridges determine if the network contains redundant paths and, if one is found, select a preferred path while placing the redundant paths in a backup or blocking state. A bridge that has only one path between itself and the root bridge is referred to as the designated bridge.
Page 773: Port Priority
AT-8100 Switch Command Line User’s Guide Port Priority If two paths have the same port cost, the bridges must select a preferred path. In some instances this can involve the use of the port priority parameter. This parameter is used as a tie breaker when two paths have the same cost.
Page 774: Forwarding Delay And Topology Changes
Chapter 53: STP, RSTP and MSTP Protocols Forwarding Delay and Topology Changes If there is a change in the network topology due to a failure, removal, or addition of any active components, the active topology also changes. This may trigger a change in the state of some blocked ports. However, a change in a port state is not activated immediately.
Page 775: Hello Time And Bridge Protocol Data Units (Bpdu)
AT-8100 Switch Command Line User’s Guide Hello Time and Bridge Protocol Data Units (BPDU) The bridges that are part of a spanning tree domain communicate with each other using a bridge broadcast frame that contains a special section devoted to carrying STP or RSTP information. This portion of the frame is referred to as the bridge protocol data unit (BPDU).
Page 776: Point-To-Point And Edge Ports
Chapter 53: STP, RSTP and MSTP Protocols Point-to-Point and Edge Ports Part of the task of configuring RSTP or MSTP is defining the port types on the switch. This relates to the devices connected to the ports. With the port types defined, RSTP or MSTP can reconfigure a network much quicker than STP when a change in network topology is detected.
Page 777 AT-8100 Switch Command Line User’s Guide Figure 150. Edge Port A port can be both a point-to-point and an edge port at the same time. It operates in full-duplex and has no spanning tree devices connected to it. Figure 151 illustrates a port functioning as both a point-to-point and edge port.
Page 778 Chapter 53: STP, RSTP and MSTP Protocols Determining whether a bridge port is point-to-point, edge, or both, can be a bit confusing. For that reason, do not change the default values for this RSTP feature unless you have a good grasp of the concept. In most cases, the default values work well.
Page 779: Mixed Stp And Rstp Networks
AT-8100 Switch Command Line User’s Guide Mixed STP and RSTP Networks RSTP IEEE 802.1w is fully compliant with STP IEEE 802.1d. A network can have both protocols. If both RSTP and STP are present in a network, they operate together to create a single spanning tree domain. Given this, if you decide to activate spanning tree on the switch, there is no reason not to use RSTP, even if the other switches are running STP.
Page 780: Spanning Tree And Vlans
Chapter 53: STP, RSTP and MSTP Protocols Spanning Tree and VLANs STP and RSTP support a single-instance spanning tree that encompasses all the ports on the switch. If the ports are divided into different VLANs, the spanning tree protocol crosses the VLAN boundaries. This point can pose a problem in networks that contain multiple VLANs that span different switches and that are connected with untagged ports.
Page 781: Rstp And Mstp Bpdu Guard
AT-8100 Switch Command Line User’s Guide RSTP and MSTP BPDU Guard This feature monitors the RSTP or MSTP edge ports on the switch for BPDU packets. Edge ports that receive BPDU packets are disabled by the switch. The benefit of this feature is that it prevents the use of edge ports by RSTP or MSTP devices.
Page 782 Chapter 53: STP, RSTP and MSTP Protocols Here are the guidelines to this feature:  BPDU guard is configured for each port and has only two possible settings: enabled or disabled. The default setting is disabled.  This feature is supported on the base ports of the switch and any fiber optic transceivers installed in the unit.
Page 783: Stp, Rstp, Mstp Loop Guard
AT-8100 Switch Command Line User’s Guide STP, RSTP, MSTP Loop Guard Although spanning tree is designed to detect and prevent the formation of loops in a network topology, it is possible in certain circumstances for the protocol to inadvertently create loops. This can happen in the unlikely situation where a link between two spanning tree devices remains active when there is an cessation of BPDUs because of a hardware or software problem.
Page 784 Chapter 53: STP, RSTP and MSTP Protocols If you configured the SNMP community strings on the switch, an SNMP trap is sent to your management workstations to notify you of the event. However, this event does not generate an entry in the switch’s log. This feature is supported on the base ports of the switch as well as on any fiber optic transceivers installed in the unit.
Page 785 AT-8100 Switch Command Line User’s Guide Figure 154. Loop Guard Example 2 But if loop guard is enabled on port 14 on switch 3, the port, instead of changing to the forwarding state, stays in the blocking state, preventing the formation of the loop. Figure 155.
Page 786 Chapter 53: STP, RSTP and MSTP Protocols The previous example illustrates how loop guard works to maintain a loop- free topology by keeping alternate ports in the blocking state when they stop receiving BPDUs. Loop guard can also work on root and designated ports that are in the forwarding state.

Page 788: Stp And Rstp Root Guard
Chapter 53: STP, RSTP and MSTP Protocols STP and RSTP Root Guard The Root Guard feature enforces the root bridge placement in a network. It ensures the port that you have configured with the Root Guard feature is a designated port. Normally, root bridge ports are all designated ports, unless two or more ports of the root bridge are connected.

Page 850: Overview
MSTP. If you are not familiar with spanning tree or RSTP, review “Overview” on page 770. Note Do not activate MSTP on an AT-8100 Allied Telesis Switch without first familiarizing yourself with the following concepts and guidelines. Unlike STP and RSTP, you cannot activate this spanning tree protocol on a switch without first configuring the protocol parameters.
Page 851: Multiple Spanning Tree Instance (Msti)
AT-8100 Switch Command Line User’s Guide Multiple Spanning Tree Instance (MSTI) The individual spanning trees in MSTP are referred to as Multiple Spanning Tree Instances (MSTIs). An MSTI can span any number of AT-8100 Switches. The switch can support up to 15 MSTIs at a time. To create an MSTI, you first assign it a number, referred to as the MSTI ID.
Page 852 Chapter 58: Multiple Spanning Tree Protocol Figure 163 illustrates the same two AT-8100 Switches and the same two virtual LANs. But in this example, the two switches are running MSTP, and the two VLANs have been assigned different spanning tree instances. Now that they reside in different MSTIs, both links remain active, enabling the VLANs to forward traffic over their respective direct link.
Page 853 AT-8100 Switch Command Line User’s Guide Figure 164. Multiple VLANs in an MSTI In this example, because an MSTI contains more than one VLAN, the links between the VLAN parts are made with tagged, not untagged, ports so that they can carry traffic from more than one virtual LAN. Referring again to Figure 164, the tagged link in MSTI 1 is carrying traffic for both the Presales and Sales VLANs while the tagged link in MSTI 2 is carrying traffic for the Design and Engineering VLANs.
Page 854: Msti Guidelines
Chapter 58: Multiple Spanning Tree Protocol MSTI Guidelines Following are several guidelines to keep in mind about MSTIs:  The AT-8100 Switch can support up to 15 spanning tree instances, including the Common and Internal Spanning Tree (CIST).  An MSTI can contain any number of VLANs. ...
Page 855: Vlan And Msti Associations
AT-8100 Switch Command Line User’s Guide VLAN and MSTI Associations Part of the task to configuring MSTP involves assigning VLANs to spanning tree instances. The mapping of VLANs to MSTIs is called associations. A VLAN, either port-based or tagged, can belong to only one instance at a time, but an instance can contain any number of VLANs.
Page 856: Ports In Multiple Mstis
Chapter 58: Multiple Spanning Tree Protocol Ports in Multiple MSTIs A port can be a member of more than one MSTI at a time if it is a tagged member of one or more VLANs assigned to different MSTIs. In this circumstance, a port might be have to operate in different spanning tree states simultaneously, depending on the requirements of the MSTIs.
Page 857: Multiple Spanning Tree Regions

Page 858: Table 94. Mstp Region
Chapter 58: Multiple Spanning Tree Protocol Table 94 illustrates the concept of regions. It shows one MSTP region consisting of two AT-8100 Switches. Each switch in the region has the same configuration name and revision level. The switches also have the same five VLANs, and the VLANs are associated with the same MSTIs.

AT-8100 Switch Command Line User’s Guide Region Following are several points to remember about regions. Guidelines  A network can contain any number of regions, and a region can contain any number of AT-8100 Switches.  The AT-8100 Switch can belong to only one region at a time. ...
Page 860: Common And Internal Spanning Tree (Cist)
Chapter 58: Multiple Spanning Tree Protocol Common and MSTP has a default spanning tree instance called the Common and Internal Spanning Tree (CIST). This instance has an MSTI ID of 0. Internal Spanning Tree This instance has unique features and functions that make it different from (CIST) the MSTIs that you create yourself.
Page 861 AT-8100 Switch Command Line User’s Guide An MSTP region can be considered as a virtual bridge. The implication is that other MSTP regions and STP and RSTP single-instance spanning trees cannot discern the topology or constitution of an MSTP region. The only bridge they are aware of is the regional root of the CIST instance.
Page 862: Summary Of Guidelines
Chapter 58: Multiple Spanning Tree Protocol Summary of Guidelines Careful planning is essential for the successful implementation of MSTP. This section reviews all the rules and guidelines mentioned in earlier sections, and contains a few new ones:  The AT-8100 Switch can support up to 15 spanning tree instances, including the CIST.
Page 863 AT-8100 Switch Command Line User’s Guide Note The AlliedWare Plus MSTP implementation complies fully with the new IEEE 802.1s standard. Any other vendor’s fully compliant 802.1s implementation is interoperable with the AlliedWare Plus implementation.
Page 864: Associating Vlans To Mstis
Chapter 58: Multiple Spanning Tree Protocol Associating VLANs to MSTIs Allied Telesis recommends that you assign all VLANs on a switch to an MSTI. You should not leave a VLAN assigned to just the CIST, including the Default_VLAN. This is to prevent the blocking of a port that should be in the forwarding state.
Page 865 AT-8100 Switch Command Line User’s Guide Figure 166. CIST and VLAN Guideline - Example 2 When port 4 on switch B receives a BPDU, the switch notes the port sending the packet belongs only to CIST. Therefore, switch B uses CIST in determining whether a loop exists.
Page 866: Connecting Vlans Across Different Regions
Chapter 58: Multiple Spanning Tree Protocol Connecting VLANs Across Different Regions Special consideration needs to be taken into account when you connect different MSTP regions or an MSTP region and a single-instance STP or RSTP region. Unless planned properly, VLAN fragmentation can occur between the VLANS of your network.
Page 867: Table 95. Two Region Examples
AT-8100 Switch Command Line User’s Guide There are several ways to address this issue. The first is to have only one MSTP region for each subnet in your network. Another approach is to group those VLANs that need to span regions into the same MSTI.
Page 868: Mstp Root Guard
Chapter 58: Multiple Spanning Tree Protocol MSTP Root Guard The Root Guard feature enforces the root bridge placement in a network. It ensures the port that you have configured with the Root Guard feature is a designated port. Normally, root bridge ports are all designated ports, unless two or more ports of the root bridge are connected.

Chapter 60: Port-based and Tagged VLANs Overview A VLAN is a group of ports that form a logical Ethernet segment on an Ethernet switch. The ports of a VLAN form an independent traffic domain in which the traffic generated by the nodes remains within the VLAN. VLANs let you segment your network through the switch’s management software so that you can group nodes with related functions into their own separate, logical LAN segments.
Page 897 AT-8100 Switch Command Line User’s Guide Virtual LANs can also span more than one switch. This makes it possible to create VLANs of end nodes that are connected to switches located in different physical locations. The switch supports the following types of VLANs you can create yourself: ...
Page 898: Port-Based Vlan Overview
Chapter 60: Port-based and Tagged VLANs Port-based VLAN Overview As the “Overview” on page 896 explains, a VLAN consists of a group of ports that form an independent traffic domain on one or more Ethernet switches. Traffic generated by the end nodes remain within their respective VLANs and does not cross over to the end nodes of other VLANs unless there is an interconnection device, such as a router or Layer 3 switch.
Page 899: Port Vlan Identifier
AT-8100 Switch Command Line User’s Guide For example, if you had a port-based VLAN named Marketing that spanned three switches, assign the Marketing VLAN on each switch the same VID. You can assign this number manually or allow the management software to do it automatically.

Chapter 60: Port-based and Tagged VLANs Tagged VLAN Overview The second type of VLAN is the tagged VLAN. VLAN membership in a tagged VLAN is determined by information within the frames that are received on a port. This differs from a port-based VLAN, where the PVIDs assigned to the ports determine VLAN membership.

Page 940: Overview
Chapter 62: GARP VLAN Registration Protocol Overview The GARP VLAN Registration Protocol (GVRP) allows network devices to share VLAN information and to use the information to modify existing VLANs or create new VLANs, automatically. This makes it easier to manage VLANs that span more than one switch. Without GVRP, you have to manually configure your switches to ensure that the various parts of the VLANs can communicate with each other across the different switches.
Page 941 AT-8100 Switch Command Line User’s Guide Figure 177 provides an example of how GVRP works. Figure 177. GVRP Example The example consists of three switches. Switches #1 and #3 have the Sales VLAN, but switch #2 does not. Consequently, the end nodes of the two parts of the Sales VLANs cannot communicate with each other.
Page 942 Chapter 62: GARP VLAN Registration Protocol Without GVRP, you would have to manually add the Sales VLAN to switch #2. But with GVRP, the VLAN is added automatically. Here is how GVRP would resolve the problem in the example. 1. Port 1 on switch #1 sends to port 2 on switch #2 a PDU that contains the VIDs of all the VLANs on the switch, including VID 11 for the Sales VLAN.
Page 943: Guidelines
VLANs and static port assignments.  The default port settings on the switch for GVRP are active, meaning that the ports participate in GVRP. Allied Telesis recommends disabling GVRP on those ports that are connected to GVRP-inactive devices, meaning devices that do not feature GVRP.
Page 944: Gvrp And Network Security
Chapter 62: GARP VLAN Registration Protocol GVRP and Network Security GVRP should be used with caution because it can expose your network to unauthorized access. If a network intruder were to connect to a switch port running GVRP and transmit a bogus GVRP PDU containing VIDs of restricted VLANs, GVRP would make the port a member of the VLANs, giving the intruder access to restricted areas of your network.
Page 945: Gvrp-Inactive Intermediate Switches
AT-8100 Switch Command Line User’s Guide GVRP-inactive Intermediate Switches If two GVRP-active devices are separated by a GVRP-inactive switch, the GVRP-active devices may not be able to share VLAN information. There are two issues involved. The first is whether the intermediate switch forwards the GVRP PDUs that it receives from the GVRP-active switches.
Page 946: Enabling Gvrp On The Switch
Chapter 62: GARP VLAN Registration Protocol Enabling GVRP on the Switch The command for enabling GVRP on the switch is found in the Global Configuration mode. It is the GVRP ENABLE command. After the command is entered, the switch immediately begins to transmit PDUs from those ports where GVRP is enabled and to learn dynamic GVRP VLANs.
Page 947: Enabling Gip On The Switch
AT-8100 Switch Command Line User’s Guide Enabling GIP on the Switch The GARP Information Propagation (GIP) component can be enabled separately from GVRP on the switch. GIP must be enabled if the switch is using GVRP. The command for activating GIP is the GVRP APPLICANT STATE ACTIVE command in the Global Configuration mode.
Page 948: Enabling Gvrp On The Ports
Chapter 62: GARP VLAN Registration Protocol Enabling GVRP on the Ports To activate GVRP on the ports so that they transmit GVRP PDUs, use the GVRP REGISTRATION NORMAL command in the Port Interface mode. Because the default setting for GVRP on the ports is enabled, you should only need to use this command if you want to enable GVRP after disabling it on a port.
Page 949: Setting The Gvrp Timers
AT-8100 Switch Command Line User’s Guide Setting the GVRP Timers The switch has a Join Timer, a Leave Timer, and a Leave All Timer. You should not change the timers unless you understand their functions. (Refer to the IEEE 802.1p standard for the definitions.) The timers have to be set the same on all GARP-active network devices, and the Join Timer and Leave Timer have to be set according to the following equation: Join Timer <= (2 x (Leave Timer))
Page 950: Disabling Gvrp Timers On The Switch
Chapter 62: GARP VLAN Registration Protocol Disabling GVRP Timers on the Switch To disable GVRP timer configurations, use the NO GVRP TIMER commands in the Global Configuration mode. They are: no gvrp timer join no gvrp timer leave no gvrp timer leaveall Use these commands to reset GVRP timers to the default values for each individual parameter.
