Link The status of the link between the port and the end node connected to the port. The possible values are: Up - A link exists between the port and the end node. Down - The port has not established a link with an end node.
Chapter 4: Port Configuration Enabling and Disabling a Port This procedure enables and disables a port. A disabled port does not forward any ingress or egress packets. You might disable a port if a problem occurs with the node or cable connected to the port. After the problem is fixed, you can enable the port to resume normal operation. You can also disable an unused port to secure it from unauthorized connections. The default setting for a port is enabled.
AT-S80 Management Software User’s Guide Setting a Port’s Speed and Duplex Mode To change a port’s speed or duplex mode, perform the following procedure: 1. From the Main Menu, type B to select Basic Configuration. The Basic Switch Configuration Menu is shown in Figure 4 on page 30 2. From the Basic Switch Configuration Menu, type P to select Port Configuration. The Port Configuration Menu is shown in Figure 13 on page 50. 3. Type M to select Set Mode.
Chapter 4: Port Configuration mismatch if the end node is operating at a fixed duplex mode of full-duplex. To avoid this problem when connecting an end node with a fixed duplex mode of full-duplex to a switch port, disable Auto-Negotiation on the port and set the port’s speed and duplex mode manually. For 1000 Mbps operation on an uplink 10/100/1000Base-T twisted pair uplink port, Allied Telesyn recommends using AutoNegotiation.
AT-S80 Management Software User’s Guide Changing the Flow Control Setting Flow control applies to ports operating in full-duplex mode. A switch port uses flow control to control the flow of ingress packets from its end node. A port using flow control issues a special frame, referred to as a PAUSE frame, as specified in the IEEE 802.3x standard, to stop the transmission of data from an end node. When a port needs to stop an end node from transmitting data, it issues this frame.

Chapter 5 Port Trunking This chapter provides information and procedures for creating a port trunk and contains the following sections: Section I: Using the Menus Interface “Port Trunking Overview” on page 58 “Creating a Port Trunk” on page 60 “Modifying a Port Trunk” on page 63 “Enabling and Disabling a Port Trunk” on page 65 57
Chapter 5: Port Trunking Port Trunking Overview Port trunking is an economical way for you to increase the bandwidth between two Ethernet switches. A port trunk is 2 to 8 ports that have been grouped together to function as one logical path. A port trunk increases the bandwidth between switches and is useful in situations where a single physical data link between switches is insufficient to handle the traffic load.
AT-S80 Management Software User’s Guide Section I: Using the Menus Interface Trunk 7 is reserved for the uplink ports 17 and 18 on the AT-FS750/16 switch and ports 25 and 26 on the AT-FS750/24 switch. You cannot add or remove ports from this trunk. To use the uplink ports as a port trunk, activate Trunk 7 as explained in “Enabling and Disabling a Port Trunk” on page 65.
Chapter 5: Port Trunking Creating a Port Trunk This procedure explains how to create a port trunk. Caution Do not connect the cables to the ports on the switches until after you have configured the trunk with the management software. Connecting the cables before configuring the software can create a loop in the network topology. A loop can cause a broadcast storm and poor network performance. To create a port trunk, perform the following procedure: 1.
AT-S80 Management Software User’s Guide The Trunk Configuration Menu is shown in Figure 15.
Chapter 5: Port Trunking The following prompt is displayed: Enable or Disable trunk group number n (E/D)> 8. Type E to enable the trunk. 9.

Do not connect the cables to the ports on the switches until after you have configured and enabled the trunk on both switches. The ports of a disabled trunk forward traffic as individual ports.
Chapter 5: Port Trunking 66 Section I: Using the Menus Interface
Chapter 6 Port Mirroring This chapter contains the procedures for setting up port mirroring. Port mirroring allows you to unobtrusively monitor the ingress and egress traffic on a port by having the traffic copied to another port.
Chapter 6: Port Mirroring Port Mirroring Overview The port mirroring feature allows you to unobtrusively monitor the ingress and egress traffic on a port by copying the traffic to another port. You can connect a network analyzer to the port where the traffic is being copied to and monitor it without impacting performance or speed. The port whose traffic you want to mirror is called the mirrored port. The port where the traffic will be copied to is called the mirroring port.
AT-S80 Management Software User’s Guide Configuring Port Mirroring To set up port mirroring, perform the following procedure: 1. From the Main Menu, type A to select Advanced Switch Configuration. The Advanced Switch Configuration Menu is shown in Figure 14 on page 60. 2. From the Advanced Switch Configuration Menu, type M to select Port Mirroring Configuration.

Chapter 7 Virtual LANs This chapter contains the procedures for creating, modifying, and deleting port-based and tagged Virtual Local Area Networks (VLANs).
Chapter 7: Virtual LANs VLAN Features A Virtual Local Area Network (VLAN) is a logical grouping of devices on different physical LAN segments that allows users to communicate as if they were physically connected to a single LAN, independent of the physical configuration of the network. With VLANs, you can segment your network and group end-nodes with related functions into their own separate, logical LAN segments. For example, the marketing personnel in you company may be spread throughout a building.
AT-S80 Management Software User’s Guide VLANs can be used to control the flow of data in your network, since the traffic generated by an end-node in a VLAN is restricted to the other endnodes in the same VLAN. In addition, VLANs can prevent data from flowing to unauthorized end-nodes. Types of VLANs The AT-FS750/16 and AT-FS750/24 Fast Ethernet switches support the following types of VLANs: Port-based VLANs Tagged VLANs The VLANs are described in the following sections.
Chapter 7: Virtual LANs Port-based VLAN Overview As explained in “VLAN Features” on page 74, a VLAN consists of a group of ports on one or more Ethernet switches that form an independent traffic domain. Traffic generated by the end nodes of a VLAN remains within the VLAN 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. A port-based VLAN is a group of ports on an Ethernet switch that form a logical Ethernet segment.
AT-S80 Management Software User’s Guide For example, if you had a port-based VLAN titled Marketing that spanned three AT-FS750 Series switches, you would assign the Marketing VLAN on each switch the same VID. You can assign this number manually or allow the AT-S80 management software to do it automatically. If you allow the management software to do it automatically, it selects the next available VID. This is acceptable when you are creating a new, unique VLAN.
Chapter 7: Virtual LANs Drawbacks of Port-based VLANs 78 Each port must be assigned a PVID. This value must match the VLAN’s VID and it must be the same for all the ports in a port-based VLAN. You must manually configure this value on a port after you assign the port to a VLAN. For instructions, refer to “Configuring the PVID of Untagged Ports” on page 89.
AT-S80 Management Software User’s Guide Port-based Example 1 Figure 17 illustrates an example of one AT-FS750/24 Fast Ethernet Switch with three port-based VLANs. (For purposes of the following examples, the Default VLAN is not shown.) Engineering VLAN (VID 3) Production VLAN (VID 4) Sales VLAN (VID 2) 1 3 5 7 9 11 13 15 17 19 21 23 2 4 6 8 10 12 14 16 18 20 22 24 AT-FS750/24 Fast Ethernet Switch WAN Router Figure 17.
Chapter 7: Virtual LANs Port-based Example 2 Each VLAN has one port connected to the router. The router interconnects the various VLANs and functions as a gateway to the WAN. Figure 18 illustrates more port-based VLANs. In this example, Sales and Engineering VLANs span two AT-FS750/24 Fast Ethernet switches, while Production VLAN is limited to just one switch.
AT-S80 Management Software User’s Guide The table below lists the port assignments for the Sales, Engineering, and Production VLANs on the switches: Sales VLAN (VID 2) Engineering VLAN (VID 3) Production VLAN (VID 4) AT-FS750/24 Switch (top) Ports 1 - 6 (PVID 2) Ports 9 - 13 (PVID 3) Ports 17, 19 - 21 (PVID 4) AT-FS750/24 Switch (bottom) Ports 2 - 4, 6, 8 (PVID 2) Ports 16, 18-20, 22 (PVID 3) none Note the following concerning the example: Sales VLAN - This VLAN spans both switches.
Chapter 7: Virtual LANs Tagged VLAN Overview The second type of VLAN supported by the AT-S80 management software 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. The VLAN information within an Ethernet frame is referred to as a tag or tagged header.
AT-S80 Management Software User’s Guide Note For explanations of VLAN name and VLAN identifier, refer back to “VLAN Name” on page 76 and “VLAN Identifier” on page 76. Tagged and Untagged Ports You need to specify which ports will be members of the VLAN. In the case of a tagged VLAN, the ports usually consist of both untagged and tagged ports. You specify which ports are tagged and which untagged when you create the VLAN.
Chapter 7: Virtual LANs Tagged VLAN Example Figure 19 illustrates how tagged ports can be used to interconnect IEEE 802.1Q-based products. Engineering VLAN (VID 3) Sales VLAN (VID 2) Production VLAN (VID 4) Legacy Server 1 3 5 7 9 11 13 15 17 19 21 23 2 4 6 8 10 12 14 16 18 20 22 24 AT-FS750/24 Fast Ethernet Switch IEEE 802.
AT-S80 Management Software User’s Guide The port assignments for the VLANs are as follows: Sales VLAN (VID 2) Engineering VLAN (VID 3) Production VLAN (VID 4) Untagged Ports Tagged Ports Untagged Ports Tagged Ports Untagged Ports Tagged Ports AT-FS750/24 Switch (top) 1, 3, 5, 6 (PVID 2) 2, 10 9, 11 to 13 (PVID 3) 2, 10 17, 19 to 21 (PVID 4) 2 AT-FS750/24 Switch (bottom) 2, 4, 6, 8 (PVID 2) 9 16, 18, 20, 22 (PVID 3) 9 none none This example is nearly identical to the “Port-based Examp
Chapter 7: Virtual LANs Creating a VLAN This section contains the procedure for creating a new port-based or tagged VLAN. This procedure assigns the VLAN a name, a VID number, and the untagged and tagged member ports. After performing this procedure, configure the untagged ports of the VLAN by adjusting their PVID values to match the virtual LAN’s VID number. The PVID value of a port must match its virtual LAN’s VID in order for a port to be considered an untagged member of the VLAN.
AT-S80 Management Software User’s Guide 3. From the VLAN Management Menu, type C to select Create VLAN. The VLAN Creation Menu is shown in Figure 21. AT-FS750/16 Local Management System VLAN Management -> VLAN Creation Menu VLAN ID : VLAN Name: Port Member ---------------------------------------------------------------------- ------------------------- ---------------------------------Set VLAN [I]D/[I]ndex [S]elect Port Member Set VLAN [N]ame [A]pply [Q]uit to Previous Menu Command> Figure 21.

Chapter 8 Quality of Service (QoS) This chapter contains the procedures for configuring Quality of Service (QoS).
Chapter 8: Quality of Service (QoS) QoS Overview When a port on an Ethernet switch becomes oversubscribed—its egress queues contain more packets than the port can handle in a timely manner—the port may be forced to delay the transmission of some packets, resulting in the delay of packets from reaching their destinations.
AT-S80 Management Software User’s Guide Table 2. Default Mappings of IEEE 802.1p Priority Levels to Egress Port Priority Queues AT-FS750 Series Egress Port Priority Queue IEEE 802.1p Traffic Class 0 0 1 0 2 0 3 1 4 2 5 2 6 3 7 3 For example, a tagged packet with a priority tag of 6 is placed in the egress port’s highest priority queue of 3, while a packet with a priority tag of 1 is placed in the lowest priority queue. Note QoS is disabled by default on the switch.
Chapter 8: Quality of Service (QoS) The default setting for Quality of Service is disabled. When the feature is disabled, all tagged packets are stored in the lowest priority egress queue of a port.
AT-S80 Management Software User’s Guide Mapping CoS Priorities to Egress Queues This procedure changes the mappings of CoS priority levels to egress priority queues. The default mappings are shown in Table 2 on page 99. This is set at the switch level and applies to all ports. This procedure also enables and disables QoS. To change the mappings or to activate or deactivate QoS, perform the following procedure: 1. From the Main Menu, type A to select Advanced Switch Configuration.

Chapter 8: Quality of Service (QoS) Changing the Temporary Priority Level of Untagged Traffic This procedure explains how to change the temporary priority level of untagged packets that enter a port, and so change the egress queue where the packets are stored. For example, you could assign a temporary priority value of 5 to the untagged packets received on a port so that the packets are stored in queue 2 on the egress port. The default priority level for untagged packets is 0.
AT-S80 Management Software User’s Guide The Port Priority Configuration Menu is shown in Figure 26.
Chapter 8: Quality of Service (QoS) received on the port are stored in queue 0 on the egress port.

Chapter 9 Rapid Spanning Tree Protocol (RSTP) This chapter describes how to configure the Rapid Spanning Tree Protocol (RSTP) on the switch and includes the following sections: Section II: Menus Interface “RSTP Overview” on page 108 “Enabling or Disabling RSTP” on page 115 “Configuring the RSTP Bridge Settings” on page 118 “Configuring STP Compatibility” on page 120 “Configuring RSTP Port Settings” on page 121 “Displaying the RSTP Topology” on page 126 107
Chapter 9: Rapid Spanning Tree Protocol (RSTP) RSTP Overview The performance of a Ethernet network can be negatively impacted by the formation of a data loop in the network topology. A data loop exists when two or more nodes on a network can transmit data to each other over more than one data path.
AT-S80 Management Software User’s Guide You can designate which switch on your network you want as the root bridge by giving it the lowest bridge priority number. You might also consider which bridge should function as the backup root bridge in the event you need to take the primary root bridge offline, and assign that bridge the second lowest bridge identifier number. You can change the bridge priority number for the switch.
Chapter 9: Rapid Spanning Tree Protocol (RSTP) Table 3 lists the RSTP port costs with Auto-Detect. Table 3. RSTP Auto-Detect Port Costs Port Speed Port Cost 10 Mbps 2,000,000 100 Mbps 200,000 1000 Mbps 20,000 Table 4 lists the RSTP port costs with Auto-Detect when the port is part of a port trunk. Table 4. RSTP Auto-Detect Port Trunk Costs Port Speed No.
AT-S80 Management Software User’s Guide Table 5 lists the values. The default value is 0. Table 5.

Chapter 10: 802.1x Port-based Network Access Control 802.1x Port-based Network Access Control Overview 802.1x Port-based Network Access Control (IEEE 802.1x) is used to control who can send traffic through and receive traffic from a switch port. With this feature, the switch will not allow an end node to send or receive traffic through a port until the user of the node logs on by entering a username and password.
AT-S80 Management Software User’s Guide Authentication Process Authenticator Ports Below is a brief overview of the authentication process that occurs between a supplicant, authenticator, and authentication server. For further details, refer to the IEEE 802.1x standard. Either the authenticator (that is, a switch port) or the supplicant can initiate an authentication prompt exchange.
Chapter 10: 802.1x Port-based Network Access Control Force-unauthorized - Places the port in the unauthorized state, ignoring all attempts by the client to authenticate. This port control setting blocks all users from accessing the network through the port and is similar to disabling a port and can be used to secure a port from use. The port continues to forward EAPOL packets, but discards all other packets, including multicast and broadcast packets. Force-authorized - Disables IEEE 802.
AT-S80 Management Software User’s Guide As mentioned earlier, the switch itself does not authenticate the user names and passwords from the clients. That is the responsibility of the authentication server, which contains the RADIUS server software. Instead, a switch acts as an intermediary for the authentication server by denying access to the network by the client until the client has provided a valid username and password, which the authentication server validates.
Chapter 10: 802.1x Port-based Network Access Control Allied Telesyn does not support connecting more than one supplicant to an authenticator port on the switch. The switch allows only one supplicant to log on per port. Note Connecting multiple supplicants to a switch port set to the Auto setting does not conform to the IEEE 802.1x standard. This can introduce security risks and can result in undesirable switch behavior.
AT-S80 Management Software User’s Guide Ports used to interconnect switches should be set to the port control setting of Force-authorized. This is illustrated in Figure 36. Switch A Port 22: 802.1x Port Control Setting: Force-authorized Port 6: 802.1x Port Control Setting: Force-authorized RADIUS Authentication Server Port 15: 802.1x Port Control Setting: Force-authorized Switch B Ports 1 to 12: 802.1x Port Control Setting: Auto Supplicants with 802.1x Client Software Figure 36.

Chapter 19 Virtual LANs This chapter contains the procedures for creating, modifying, and deleting port-based and tagged Virtual Local Area Networks (VLANs) from a web browser management session.
Chapter 19: Virtual LANs Creating a VLAN This section contains the procedure for creating a new port-based or tagged VLAN. This procedure assigns the VLAN a name, a VID number, and the untagged and tagged member ports. After performing this procedure you must adjust the PVID values of the untagged ports of the VLAN to match the virtual LAN’s VID number. In order for a port to be considered an untagged member of a VLAN, its PVID value must be changed to match the VID of the virtual LAN.
AT-S80 Management Software User’s Guide If the VLAN will be unique in you network, then the name should be unique as well. If the VLAN will be part of a larger VLAN that spans multiple switches, then the name for the VLAN should be the same on each switch where nodes of the VLAN are connected. 4. In the Static Tagged row, click the dialog circles of those ports on the switch that are to be tagged or untagged members of the new VLAN.
Chapter 19: Virtual LANs Configuring the PVID of Untagged Ports This procedure adjusts a port’s VID value. The PVID value determines the VLAN in which the port is an untagged member. A port is an untagged member of the VLAN whose VID value matches its PVID. A port can be an untagged member of only one VLAN at a time. The ports of a new VLAN are initially designated as tagged ports. Their PVID values retain their previous settings when they are assigned to a new VLAN.
AT-S80 Management Software User’s Guide 2. Click the PVID field of the port whose value you want to change and enter the new PVID value for the port. The PVID must be equal to the VID of the VLAN where you want the port to be an untagged member. For example, to make Port 10 an untagged member of a VLAN that has a VID of 12, you would change its PVID to 12.
Chapter 19: Virtual LANs Displaying the VLANs To display the VLANs, perform the following procedure: 1. From the Advanced Config menu, select VLAN Config and VLAN Info. The VLAN Information page is shown in Figure 59. This pages lists the VLANs on the switch. Figure 59.

Chapter 20 Quality of Service (QoS) This chapter contains the procedure for configuring Quality of Service (QoS).
Chapter 20: Quality of Service (QoS) Mapping CoS Priorities to Egress Queues This procedure changes the mappings of CoS priority levels to egress priority queues. The default mappings are shown in Table 2 on page 99. This is set at the switch level and applies to all ports. This procedure also enables and disables QoS. To change the mappings or to activate or deactivate QoS, perform the following procedure: 1. From the Advanced Config menu, select QoS Config and then select Traffic Class Config.
AT-S79 Management Software User’s Guide Note The switch does not alter the original priority level in tagged frames. Frames leave the switch with the same priority level they had when they entered the switch.
Chapter 20: Quality of Service (QoS) Changing the Temporary Priority Level of Untagged Traffic This procedure explains how to change the temporary priority level of untagged packets that enter a port, and so change the egress queue where the packets are stored. For example, you could assign a temporary priority value of 5 to the untagged packets received on a port so that the packets are stored in queue 2 on the egress port. The default priority level for untagged packets is 0.
AT-S79 Management Software User’s Guide Queue Displays the queue where the untagged packets received on the port are stored on the egress port. For example, in Figure 63 on page 212 the untagged traffic received on port 2 is assigned a temporary priority level of 5 and is stored in queue 2 on the egress port. Override Displays whether the temporary priority value is being applied to the untagged packets on the port.
