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-S81 Management Software User’s Guide 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 creates a loop in your network topology, which can result in broadcast storms and poor network performance.

Chapter 8 Power Over Ethernet This chapter contains the following sections: Section I: Using the Menus Interface “PoE Overview” on page 88 “Configuring PoE” on page 91 87
Chapter 8: Power Over Ethernet PoE Overview The twisted pair ports on the AT-8000/8POE Fast Ethernet Switch feature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over the same twisted pair cables used to carry network traffic. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices. A device that receives its power over an Ethernet cable is called a powered device.
AT-S81 Management Software User’s Guide There are three priority levels: Critical High Low Ports designated as critical receive power before any other ports with a lower priority. Always assign the critical priority level to your most important network devices. If there is not enough power to support all the ports set to the critical priority level, then power is provided to the ports based on port number, in ascending order.
Chapter 8: Power Over Ethernet Power Over Ethernet menu, shown in Figure 18 on page 91. Even though each port is capable of supplying up to 15.4 W, the standard calls for a maximum power consumption of 12.95 W, 2.45 W less than the port can supply. This extra capability is to compensate for possible line loss. Some power is likely to be lost on the twisted pair cable as it travels from the switch to the device. For devices that require 12.95 W, the extra watts act as compensation for this possible loss.
AT-S81 Management Software User’s Guide Configuring PoE This section contains the following procedures: Displaying the PoE Configuration “Displaying the PoE Configuration,” next “Changing the PoE Port’s Admin Setting” on page 92 “Setting the PoE Port’s Priority” on page 93 To display the current PoE Configuration, 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 15 on page 75. 2.
Chapter 8: Power Over Ethernet The Power Over Ethernet Configuration menu displays information about the PoE status of each port and also allows you to configure the port’s status and priority. The table includes the following items of information: Admin The status of the port, either up or down. To change the Admin selection, refer to “Changing the PoE Port’s Admin Setting” on page 92. Status Whether a PoE device is being powered or not by that port.
AT-S81 Management Software User’s Guide Setting the PoE Port’s Priority The priority defines which port and its attached PoE powered device should receive priority for the available power over other PoE devices. For more information about port priority, refer to “Port Prioritization for Power Allocation” on page 88. To set the port priority, perform the following procedure: 1. Type I to select Set PoE Port Priority. The following prompt is displayed: Enter port number > 2.
Chapter 8: Power Over Ethernet 94 Section I: Using the Menus Interface
Chapter 9 Virtual LANs This chapter contains the procedures for creating, modifying, and deleting and tagged Virtual Local Area Networks (VLANs).
Chapter 9: 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 your company may be spread throughout a building.
AT-S81 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 9: Virtual LANs VLAN Overview This VLAN overview contains the following sections: “VLAN Name,” next “VLAN Identifier” on page 98 “VLAN Port Members” on page 98 “Port VLAN Identifier” on page 98 “Incoming and Outgoing Tagged and Untagged Frames” on page 99 “Guidelines for Creating a VLAN” on page 100 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-S81 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 9: Virtual LANs 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 untagged 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). These frames are untagged after transmission from the switch.
AT-S81 Management Software User’s Guide Untagged VLAN Figure 19 illustrates how VLANs with untagged port members can be interconnected. In this example, the Sales VLAN spans two AT-8000/ 8POE Fast Ethernet switches, while the Production VLAN is limited to just one switch.
Chapter 9: Virtual LANs 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-S81 Management Software User’s Guide Tagged VLAN Example Figure 20 illustrates how tagged and untagged ports can be used to interconnect IEEE 802.1Q-based products.
Chapter 9: Virtual LANs 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 (PVID 2) 6, 9 3, 5, & 7 (PVID 3) 6, 9 AT-8000/8POE Fast Ethernet Switch (bottom) 2, 4 (PVID 2) 5 3, 6,& 8 (PVID 3) 5 Ports 1 and 3 on the top switch and ports 2 and 4 on the bottom switch are assigned a PVID of 2 and are untagged members of only V
AT-S81 Management Software User’s Guide Creating a VLAN This section contains the procedure for creating a new 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 members 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.
Chapter 9: Virtual LANs 3. From the VLAN Management Menu, type C to select Create VLAN. The VLAN Creation Menu is shown in Figure 22.

When the VLAN is complete, type A to select Apply and apply the VLAN settings.
Chapter 9: Virtual LANs Configuring the Port PVID This procedure adjusts a port’s VID value. The PVID value determines if a port is a tagged or untagged member of a VLAN. A port is an untagged member of a VLAN whose VID value matches its PVID. A port is a tagged member of a VLAN whose VID does not match the PVID. (The PVID must equal on of the port’s VIDs.) A port can be a tagged member of a VLAN only if the port is a member of more than one VLAN at the same time.
AT-S81 Management Software User’s Guide Note If you specify a PVID that does not correspond to any VIDs on the switch, the management software creates a new VLAN with a VID that equals the PVID. The VLAN is not assigned any name. 7. Repeat steps 4 through 6 to configure additional ports.

Chapter 10 Quality of Service (QoS) This chapter contains the procedures for configuring the Quality of Service (QoS) parameters of the switch.
Chapter 10: 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-S81 Management Software User’s Guide Table 3. 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 10: 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-S81 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 3 on page 119. 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 11: 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-S81 Management Software User’s Guide network security by 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 12: 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-S81 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 12: Rapid Spanning Tree Protocol (RSTP) Table 4 lists the RSTP port costs with Auto-Detect. Table 4. RSTP Auto-Detect Port Costs Port Speed Port Cost 10 Mbps 2,000,000 100 Mbps 200,000 1000 Mbps 20,000 Table 5 lists the RSTP port costs with Auto-Detect when the port is part of a port trunk. Table 5. RSTP Auto-Detect Port Trunk Costs Port Speed No.
AT-S81 Management Software User’s Guide Table 6 lists the values. The default value is 0. Table 6. Port Priority Value Increments Port Priority Port Priority 0 128 16 144 32 160 48 176 64 192 80 208 96 224 112 240 If two paths have the same port cost and the same priority, then the ports with the lowest port MAC addresses become the root ports of their respective bridges.
Chapter 12: 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.

Chapter 13 802.1x 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 160 “Configuring 802.
Chapter 13: 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-S81 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 13: 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-S81 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 13: 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-S81 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 39.
