Type Q to select Quit to previous menu and save your changes.
Chapter 4: Port Configuration 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 68 “Creating a Port Trunk” on page 70 “Modifying a Port Trunk” on page 73 “Enabling and Disabling a Port Trunk” on page 74 67
Chapter 5: Port Trunking Port Trunking Overview A port trunk is an economical way for you to increase the bandwidth between the Ethernet switch and another networking device, such as a network server, router, workstation, or another Ethernet switch. A port trunk is a group of ports that have been grouped together to function as one logical path.
AT-S79 Management Software User’s Guide manufacturer. For this reason static trunks are typically employed only between devices from the same vendor. That is not to say that an Allied Telesis layer 2 managed switch cannot form a static trunk with a device from another manufacturer; but there is the possibility that the implementations of static trunking on the two devices might not be compatible. Also, note that a static trunk does not provide for redundancy or link backup.
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 you have configured the trunk with the management software. Connecting the cables before configuring the software creates a loop in your network topology, which can result in broadcast storms and poor network performance. To create a port trunk, perform the following procedure: 1.
AT-S79 Management Software User’s Guide The Trunk Configuration Menu is shown in Figure 17. Advanced Switch Configuration -> Trunk Configuration Menu Group ------1 2 3 4 5 6 7 Status Port Members Trunk ID -------------- --------------------- ---------Disabled 1 Disabled 2 Disabled 3 Disabled 4 Disabled 5 Disabled 6 Disabled 7 ----------------------- ----------------------------[A]dd Trunk Member [S]et Trunk Status [R]emove Trunk Member [Q]uit to previous menu Command> Figure 17.
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. Type Q to select Quit to previous menu and save your changes. The trunk is now operational on the switch. 10. Configure the port trunk on the other switch and connect the cables.
AT-S79 Management Software User’s Guide Modifying a Port Trunk This procedure adds and removes ports from a port trunk. Caution Before modifying a trunk, disconnect the cables from the ports of the trunk. Adding or removing ports from a trunk without first disconnecting the cables can create loops in your network topology, which can cause poor network performance and broadcast storms. To add or remove ports from a trunk, perform the following procedure: 1.
Chapter 5: Port Trunking Enabling and Disabling a Port Trunk This procedure enables and disables a port trunk. Note the following before performing this procedure: Do not enable a port trunk until after you have configured the trunk on both switches. Do not connect the cables to the ports on the switches until after you have configured and enabled the trunk on both switches. Caution Before disabling a port trunk, first disconnect all cables from the ports of the trunk.
Chapter 6 IGMP Snooping This chapter explains how to activate and configure the Internet Group Management Protocol (IGMP) snooping feature on the switch.
Chapter 6: IGMP Snooping IGMP Snooping Overview IGMP enables IPv4 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. A node that wants to become a member of a multicast group responds to a query by sending a report.
AT-S79 Management Software User’s Guide 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 network performance. The AT-GS950 switches maintain a list of multicast groups through an adjustable timeout value, which controls how frequently it expects to see reports from end nodes that want to remain members of multicast groups, and by processing leave requests.
Chapter 6: IGMP Snooping Configuring IGMP Snooping The procedures in this section describe how to enable or disable IGMP snooping, set the age-out timer, and view group members. See the following procedures: Enabling or Disabling IGMP Snooping “Enabling or Disabling IGMP Snooping” on page 78 “Setting the Age-out Timer” on page 80 “Setting Group Members” on page 80 To activate or deactivate IGMP snooping on the switch, perform the following procedure: 1.

Chapter 10 Virtual LANs This chapter contains the procedures for creating, modifying, and deleting port-based and tagged Virtual Local Area Networks (VLANs).
Chapter 10: Virtual LANs VLAN Overview A VLAN is a group of ports on an Ethernet switch that form a logical Ethernet segment. The ports of a VLAN form an independent traffic domain where the traffic generated by the nodes of a VLAN remains within the VLAN. With VLANs, you can segment your network through the switch’s AT-S79 management software and so be able to group nodes with related functions into their own separate, logical LAN segments.
AT-S79 Management Software User’s Guide But with VLANS, you can change the LAN segment assignment of an end node connected to the switch through the switch’s AT-S79 management software. You can change the VLAN memberships through the management software without moving the workstations physically, or changing group memberships by moving cables from one switch port to another. In addition, a virtual LAN can span more than one switch.
Chapter 10: Virtual LANs Port-based VLAN Overview As explained in “VLAN Overview” on page 102, a VLAN consists of a group of ports on an Ethernet switch 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 a Gigabit Ethernet Switch that form a logical Ethernet segment.
AT-S79 Management Software User’s Guide Tagged VLAN Overview The second type of VLAN supported by the AT-S79 management software is the tagged VLAN. VLAN membership in a tagged VLAN is determined by information within the frames that are received by a port and the VLAN configuration of each port. The VLAN information within an Ethernet frame is referred to as a tag or tagged header.
Chapter 10: Virtual LANs Port VLAN Identifier General Rules for Creating a Tagged VLAN 106 When an untagged packet is received on a port in a tagged VLAN, it is assigned to one of the VLANs of which that port is a member. The deciding factor in this process is the Port VLAN Identifier (PVID). Both tagged and untagged ports in a tagged VLAN must have a PVID assigned to them. The default value of the PVID for each port is 1.
AT-S79 Management Software User’s Guide 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 you have performed this procedure, you must configure the untagged ports of the VLAN by adjusting their PVID values to match the virtual LAN’s VID number.
Chapter 10: Virtual LANs 3. Type V to select 802.1Q VLAN. The Tagged-based VLAN configuration Menu is shown in Figure 24.

AT-S79 Management Software User’s Guide 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 can be an untagged member of only one VLAN at a time. A port is an untagged member of the VLAN whose VID value matches its PVID. The ports of a new VLAN are initially designated as tagged ports by the software. Their PVID values retain their previous settings when they are assigned to a new VLAN.

Chapter 11 Simple Network Management Protocol (SNMP) This chapter explains how to activate SNMP management on the switch and how to create, modify, and delete SNMPv1 and SNMPv2c community strings.
Chapter 11: Simple Network Management Protocol (SNMP) SNMP Overview You can manage a switch by viewing and changing the management information base (MIB) objects on the device with the Simple Network Management Program (SNMP). The AT-S79 Management Software supports SNMPv1 and SNMPv2c. To manage a switch using an SNMP application program, you must do the following: Activate SNMP management on the switch. The default setting for SNMP management is disabled.
AT-S79 Management Software User’s Guide Community String Attributes A community string has attributes for controlling who can use the string and what the string will allow a network management to do on the switch. The community string attributes are defined below: Community String Name A community string must have a name of one to eight alphanumeric characters. Spaces are allowed. Access Mode This attribute defines the permissions of a community string. There are two access modes: Read and Read/Write.
Chapter 11: Simple Network Management Protocol (SNMP) Trap receivers are the devices, typically management workstations or servers, that you want to receive the traps sent by the switch. You specify the trap receivers by their IP addresses. You assign the IP addresses to the community strings. Each community string can have up to eight trap IP addresses. It does not matter which community strings you assign your trap receivers.
AT-S79 Management Software User’s Guide Default SNMP Community Strings The AT-S79 Management Software provides two default community strings: public and private. The public string has an access mode of ReadOnly and the private string has an access mode of Read/Write. If you activate SNMP management on the switch, you should delete or disable the private community string, which is a standard community string in the industry.

Chapter 12 Quality of Service (QoS) This chapter contains the procedures for configuring the Quality of Service (QoS) parameters of the switch.
Chapter 12: 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-S79 Management Software User’s Guide Table 2. Default Mappings of IEEE 802.1p Priority Levels to Egress Port Priority Queues AT-GS950 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 12: Quality of Service (QoS) One last thing to note is that CoS does not change the priority level in a tagged packet. The packet leaves the switch with the same priority it had when it entered. This is true even if you change the default priority-toegress queue mappings. 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-S79 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 145. This is set at the switch level and applies to all ports. This procedure also enables and disables QoS. To change the mappings, perform the following procedure: 1. From the Main Menu, type A to select Advanced Switch Configuration.
Chapter 12: Quality of Service (QoS) The Traffic Class Configuration Menu is shown in Figure 34.

Enter the new egress queue number for the traffic class. The range is 0 to 3. 0 is the lowest priority queue and 3 is the highest. You can specify only one egress queue. 6. Type Q to select Quit to previous menu and save your changes.
Chapter 12: Quality of Service (QoS) Configuring CoS As explained in “QoS Overview” on page 144, a packet received on a port is placed it into one of four priority queues on the egress port according to the switch’s mapping of 802.1p priority levels to egress priority queues. The default mappings are shown in Table 2 on page 145. You can override the mappings at the port level by assigning a different egress queue to a port.
AT-S79 Management Software User’s Guide The Port Priority Configuration Menu is shown in Figure 35.
Chapter 12: Quality of Service (QoS) 4. To configure a port that is not a member of a trunk, type R to select Set Priority Queue. To configure the ports of a port trunk, type T to select Set Trunk Priority Queue. The following prompt is displayed if you are configuring a port: Set Priority Queue-> Enter port number > The following prompt is displayed if you are configuring a trunk: Enter trunk group number > 5. Enter the port or trunk number that you want to configure.
AT-S79 Management Software User’s Guide Note The tagged information in a frame is not changed as the frame traverses the switch. A tagged frame leaves a switch with the same priority level that it had when it entered. The default for this parameter is disabled, meaning that the priority level of tagged frames is determined by the priority level specified in the frames themselves.

Chapter 13 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 I: Using the Menus Interface “RSTP Overview” on page 156 “Enabling or Disabling RSTP” on page 163 “Configuring the RSTP Bridge Settings” on page 166 “Configuring STP Compatibility” on page 168 “Configuring RSTP Port Settings” on page 169 “Displaying the RSTP Topology” on page 174 155
Chapter 13: 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-S79 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. In addition, you may consider which bridge should function as the backup root bridge in the event you need to take the primary root bridge offline. Then assign the back up root bridge the second lowest bridge identifier number. You can change the bridge priority number for the switch.
Chapter 13: 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-S79 Management Software User’s Guide Table 5 lists the values. The default value is 0. Table 5.

Chapter 13: Rapid Spanning Tree Protocol (RSTP) There are two possible selections: Point-to-point port Edge port The default setting for the RSTP port point-to-point status is automatic. With the automatic setting, the point-to-point status is True of the port is operating in full-duplex mode. If the port is operating in half-duplex mode, then the point-to-point status is False. Figure 36 illustrates two AT-GS950/24 switches that have been connected with one data link.

Chapter 17 802.1x Port-based Network Access Control This chapter contains information about and the procedure for configuring the 802.1x Port-based Network Access Control feature. This chapter includes the following sections: Section I: Using the Menus Interface “802.1x Port-based Network Access Control Overview” on page 192 “Guest VLANs” on page 198 “Configuring 802.
Chapter 17: 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-S79 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 17: 802.1x Port-based 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-S79 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 17: 802.1x Port-based 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 Telesis recommends use the Forceauthorized setting of the Port Control feature on ports that are connected to more than one end node, such as a port connected to another switch or to a hub.
AT-S79 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 48. 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 48.
Chapter 17: 802.1x Port-based Network Access Control Guest VLANs An authenticator port in the unauthorized state typically accepts and transmits only 802.1x packets while waiting to authenticate a supplicant. However, you can configure an authenticator port to be a member of a Guest VLAN when no supplicant is logged on. Any client using the port is not required to log on and has full access to the resources of the Guest VLAN. If the switch receives 802.
