Trunk The trunk group number. This column contains the number of the port trunk if the port is a member of a trunk. To configure a trunk, refer to Chapter 6, “Port Trunking” on page 81. Type The port type. The type for an RJ-45 copper port is 10/100/1000BaseT.
Chapter 5: Port Configuration Enabling or Disabling a Port This procedure enables or disables a port. You may want to disable a port and prevent packets from being forwarded if a problem occurs with the node or cable connected to the port. After the problem has been 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.

Chapter 5: Port Configuration 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.
AT-S84 Management Software User’s Guide Changing the Flow Control Setting A switch port uses flow control to control the flow of ingress packets from its end node. 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.
Chapter 5: Port Configuration Changing the Back Pressure Setting Back pressure performs much the same function as flow control. Both are used by a port to control the flow of ingress packets. Flow control applies to ports operating in full-duplex; back pressure applies to ports operating in half-duplex mode. When a twisted pair port on the switch operating in half-duplex mode needs to stop an end node from transmitting data, it forces a collision.

Chapter 5: Port Configuration 80 Section I: Using the Menus Interface
Chapter 6 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 82 “LACP Trunks” on page 84 “Setting Up a Port Trunk” on page 88 “Setting Up an LACP Trunk” on page 92 81
Chapter 6: 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-S84 Management Software User’s Guide compatible. Also note that a static trunk does not provide for redundancy or link backup. If a port in a static trunk loses its link, the trunk’s total bandwidth is diminished. Though the traffic carried by the lost link is shifted to one of the remaining ports in the trunk, the bandwidth remains reduced until the lost link is reestablished or you reconfigure the trunk by adding another port to it.
Chapter 6: Port Trunking LACP Trunks An LACP (Link Aggregation Control Protocol) trunk is another type of port trunk. It performs the same function as a static trunk. It increases the bandwidth between two network devices by distributing the traffic load over multiple physical links. The advantage of an LACP trunk over a static port trunk is its flexibility. While implementations of static trunking tend to be vendor specific, the AT-S84 implementation of LACP is compliant with the IEEE 802.3ad standard.
AT-S84 Management Software User’s Guide When a trunk is created, its default status is Disabled. This means that the trunk does not pass network traffic or send/receive LACP data units (LACPDU) until the trunk status is changed accordingly. When a trunk is set to Active status, the trunk ports are all available as part of the active LACP trunk. The trunk ports of an active trunk will all send and receive LACPDUs.
Chapter 6: Port Trunking Two conditions must be met in order for a port that is a member of an aggregate trunk to function in the standby mode. First, the number of ports in the trunk must exceed the highest allowed number of active ports and, second, the port must be receiving LACPDU packets from the other device. A port functioning in the standby mode does not forward network traffic, but it does continue to send LACPDU packets.
AT-S84 Management Software User’s Guide device can support in a trunk. If the number is less than eight, the maximum number for the AT-9000/24 Gigabit Ethernet switch, you should probably assign a higher system LACP priority to the other vendor’s switch. If it is more than eight, assign the higher priority to the AT-9000/24 Gigabit Ethernet switch. This can avoid a possible conflict between the devices if some ports are placed in the standby mode when the devices create the trunk.
Chapter 6: Port Trunking Setting Up a Port Trunk This section contains the following procedures for working with port trunks: Creating a Port Trunk “Creating a Port Trunk,” next “Modifying a Port Trunk” on page 90 “Enabling or Disabling a Port Trunk” on page 91 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.
AT-S84 Management Software User’s Guide The Trunk Configuration Menu is shown in Figure 22.
Chapter 6: Port Trunking 8. Type M to select Manual Trunk for a basic trunk without LACP handling. The A and P options apply to LACP trunks. See “Setting Up an LACP Trunk” on page 92 for more information. The trunk is now operational on the switch. 9. Configure the port trunk on the other switch and connect the cables. Modifying a Port Trunk This procedure adds and removes ports from a port trunk. Note Disconnect the cables from the ports of the trunk on the switch before modifying it.
AT-S84 Management Software User’s Guide You can specify the ports individually, separated by commas (for example, 1,2,5), as a range of ports separated by a hyphen (for example, 2-4), or both (for example, 1,3, 6-8). 6. Modify the port trunk on the other switch and reconnect the cables. Enabling or Disabling a Port Trunk This procedure enables and disables a port trunk.

Chapter 8 Virtual LANs and GVRP This chapter contains the procedures for creating, modifying, and deleting and tagged Virtual Local Area Networks (VLANs).
Chapter 8: Virtual LANs and GVRP 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.
AT-S84 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.
Chapter 8: Virtual LANs and GVRP VLAN Overview This VLAN overview contains the following sections: “VLAN Name,” next “VLAN Identifier” on page 106 “VLAN Port Members” on page 106 “Port VLAN Identifier” on page 106 “Incoming and Outgoing Tagged and Untagged Frames” on page 107 “Guidelines for Creating a VLAN” on page 108 VLAN Name To create a port-based VLAN, you must give it a name. The name should reflect the function of the network devices that are be members of the VLAN.
AT-S84 Management Software User’s Guide Note The switch is preconfigured with the Default_VLAN only. All ports on the switch are initially members of the Default_VLAN. If a port is assigned to be a new member of a VLAN, its membership can be defined as either tagged or untagged. Tagged Port Members A port is a tagged member of a VLAN when the PVID does not equal the VID. In this case, the port must be a member of two or more VLANs.
Chapter 8: Virtual LANs and GVRP Outgoing Frames Frames being transmitted from the switch retain their VLAN tag information in the frame header if the frame’s tag does not match the PVID of the port (a tagged member of that VLAN). These frames are tagged after transmission from the switch. The VLAN tag information in the header of the frame is stripped from the frame’s header if the tag matches the PVID of the port (an untagged member of the VLAN).
AT-S84 Management Software User’s Guide Untagged VLAN Figure 26 illustrates how VLANs with untagged port members can be interconnected. In this example, the Sales VLAN spans two AT-9000/24 Gigabit Ethernet switches, while the Production and Engineering VLANs are limited to just one switch.
Chapter 8: Virtual LANs and GVRP The table below lists the port numbers for the Sales, Engineering, and Production VLANs on the switches. In this example, all ports are untagged members of their respective VLANS.
AT-S84 Management Software User’s Guide Tagged VLAN Example Figure 27 illustrates how tagged and untagged ports can be used to interconnect IEEE 802.1Q-based products.
Chapter 8: Virtual LANs and GVRP The port assignments for the VLANs are as follows: Sales VLAN (VID 2) Engineering VLAN (VID 3) Untagged Port Members Tagged Port Members Untagged Port Members Tagged Port Members AT-8000/8POE Fast Ethernet Switch (top) 1, 2, 5, 7, 24 (PVID 2) None 9, 11, 13, 21, 23 (PVID 3) 14, 24 AT-8000/8POE Fast Ethernet Switch (bottom) 2, 4, 13 (PVID 2) None 10, 12, 18, 22 (PVID 3) 13 Ports 1, 2, 5, and 7 on the top switch and ports 2, 4, and 13 on the bottom switch are

Chapter 9 Quality of Service (QoS) This chapter contains the procedures for configuring the Quality of Service (QoS) parameters of the switch.
Chapter 9: 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-S84 Management Software User’s Guide Table 2. Default Mappings of IEEE 802.1p Priority Levels to Egress Port Priority Queues 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 9: 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 queue of a port.
AT-S84 Management Software User’s Guide Mapping CoS Priorities to Egress Queues This procedure explains how to change the default mappings of CoS priorities to egress priority queues, shown in Table 2 on page 127.

Chapter 10: IGMP Snooping IGMP Snooping Overview The Internet Group Management Protocol (IGMP) enables routers to create lists of nodes that are members of multicast groups. (A multicast group is a group of end nodes that want to receive multicast packets from a multicast application.) The router creates a multicast membership list by periodically sending out queries to the local area networks connected to its ports.
AT-S84 Management Software User’s Guide restricting the flow of multicast packets only to those switch ports connected to host nodes. Without IGMP snooping a switch would have to flood multicast packets out all of its ports, except the port on which it received the packet. Such flooding of packets can negatively impact switch and network performance.

Chapter 11 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 146 “Enabling or Disabling RSTP” on page 153 “Configuring the RSTP Bridge Settings” on page 156 “Configuring STP Compatibility” on page 158 “Configuring RSTP Port Settings” on page 159 “Displaying the RSTP Topology” on page 164 145
Chapter 11: 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-S84 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 11: 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.

Chapter 12 802.1x Network Access Control This chapter contains information about and the procedure for configuring 802.1x Network Access Control. It includes the following sections: Section I: Using the Menus Interface “802.1x Network Access Control Overview” on page 168 “Configuring 802.
Chapter 12: 802.1x Network Access Control 802.1x Network Access Control Overview 802.1x 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-S84 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 12: 802.1x Network Access Control server. Each client that attempts to access the network is uniquely identified by the switch using the client's MAC address. 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.
AT-S84 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 12: 802.1x Network Access Control 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. To avoid this, Allied Telesyn recommends use the Forceauthorized setting on those ports that are connected to more than one end node, such as a port connected to another switch or to a hub.
AT-S84 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 47.

Chapter 22 Virtual LANs This chapter contains the procedures for creating, modifying, and deleting and tagged Virtual Local Area Networks (VLANs) from a web browser management session.
Chapter 22: Virtual LANs Creating a VLAN This section contains the procedure for creating a new or tagged VLAN. This procedure assigns the VLAN a name, a VID number, and the untagged and tagged member ports. After performing this procedure, the PVID values of the untagged ports of the VLAN must be adjusted 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-S84 Management Software User’s Guide The name can contain up to 32 characters including spaces but not including special characters such as asterisks (*) or exclamation points (!). 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.
Chapter 22: 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-S84 Management Software User’s Guide The VLAN Port Configuration page is shown in Figure 76. Figure 76. PVID Page 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.
