Section I Overview The chapter in this section provides a brief overview of the AT-S45 management software. It explains some of the functions that you can perform with the management software and reviews the different methods for accessing the AT-S45 software on an AT-9410GB Gigabit Ethernet Switch.
Chapter 1 Overview The AT-S45 management software is intended for the AT-9410GB Gigabit Ethernet Switch. You use the software to adjust the operating parameters of the switch.
AT-S45 User’s Guide To actively manage a switch, such as to change or adjust its operating parameters, then you must access the switch’s AT-S45 management software. The AT-S45 software has a menu interface that makes it very easy to use. It also has a special interface for managing a switch with a web browser. There are four different ways that you can access the management software on an AT-9410GB Gigabit Ethernet switch. The methods are referred to as management sessions in this guide.
AT-S45 User’s Guide Local Management Session You establish a local management session with an AT-9410GB Gigabit Ethernet switch by connecting a terminal or a PC with a terminal emulator program to the RS232 Terminal port on the front panel of the switch, using the null-modem management cable include with the switch. This type of management session is referred to as “local” because you must be physically close to the switch, such as in the wiring closet where the switch is located.
AT-S45 User’s Guide Telnet Management Session Any management workstation on your network that has the Telnet application protocol can be used to manage an AT-9410GB Gigabit Ethernet Switch. This type of management session is referred to in this guide as a remote management session because you can manage the switch from any workstation on your network that has the application protocol. Establishing a Telnet management session with an AT-9410GB switch requires that the switch have an IP address.
AT-S45 User’s Guide Web Browser Management Session You can also use a web browser to manage a switch. This too is a type of remote management, just like a Telnet management session, because any workstation on your network that has a web browser can be used to manage a switch. Note For instructions on starting a web browser management session, refer to Starting a Web Browser Management Session on page 148.
AT-S45 User’s Guide SNMP Management Session Another way to remotely manage an AT-9410GB switch is with an SNMP management program. A familiarity with Management Information Base (MIB) objects is necessary to manage a switch with an SNMP management program.
Section II Local and Telnet Management The chapters in this section explain how to manage an AT-9410GB Gigabit Ethernet switch from a local or Telnet management session.
Chapter 2 Starting a Local or Telnet Management Session This chapter contains the procedure for starting a local or Telnet management session on an AT-9410GB Gigabit Ethernet Switch.
AT-S45 User’s Guide Local Management Session On the front panel of the AT-9410GB switch is a port labelled RS232 Terminal Port. You use this port to establish a local management session with the switch’s AT-S45 management software. A local management session is so named because you must be close to the switch, usually within a few meters, to start this type of management session. This typically means that you must be in the wiring closet where the switch is located.
AT-S45 User’s Guide Starting a Local Management Session To start a local management session, perform the following procedure: 1. Connect one end of the management cable included with the switch to the RS232 Terminal Port on the unit.

Pressing the letter Q from a submenu or window returns you to the previous menu.
AT-S45 User’s Guide Telnet Management Session You can use the Telnet application protocol from a workstation on your network to manage an AT-9410GB Gigabit Ethernet Switch. This type of management is referred to as remote management because you do not have to be physically close to the switch to start the session, such as with a local management session. Any workstation on your network that has the application protocol can be used to manage the switch.
Chapter 3 Basic Switch Parameters This chapter contains a variety of information and procedures. There is a discussion on when to assign an IP address to a switch and the different ways that you can go about it. There are also procedures for resetting the switch, activating the original switch default settings, and more.
AT-S45 User’s Guide When Does an AT-9410GB Switch Need an IP Address? One of your first tasks as you begin to build your network will be to determine which of the switches in your network should be assigned unique IP addresses. The following two subsections help to explain how to go about making this decision.
AT-S45 User’s Guide Configuring an IP Address The procedure in this section explains how to manually assign an IP address, subnet mask, and gateway address to the switch from a local or Telnet management session. (If you want the switch to obtain its IP configuration from a DHCP server on your network, go to the procedure Activating the DHCP Service on page 34.) To manually set a switch’s IP address, perform the following procedure: 1.

AT-S45 User’s Guide Configuring System Administration Information The procedure in this section explains how to assign a name to the switch, along with other optional information, such as the name of the administrator responsible for maintaining the unit and the location of the switch. To set the name, contact or location information on a switch, perform the following procedure: 1. From the Main Menu, type A to select the System Administration Configuration.
AT-S45 User’s Guide Note It is advised that you assign each switch a name. The names can help you identify the various switches when you manage them, and can help you avoid performing configuration procedures on the wrong switch. Set System [L]ocation This command sets the location of the Gigabit Ethernet switch (for example, 4th Floor - wiring closet 402B). This parameter is optional.
AT-S45 User’s Guide Activating the DHCP Service This application protocol was developed to simplify network management. It is used to automatically assign IP configuration information to the devices on your network, such as an IP address, subnet mask, and, in some instances, a default gateway address. The AT-9410GB Gigabit Ethernet Switch supports this protocol and can obtain its IP configuration information from a DHCP server on your network.
AT-S45 User’s Guide The System IP Configuration Menu in Figure 6 is displayed. AT-9410GB Local Management System Enter the character in square brackets to select option Basic Switch Configuration -> System IP Configuration Menu MAC Address: IP Address: Subnet Mask: Default Gateway: DHCP Mode: 00:30:AB:00:09:20 149.35.19.168 255.255.253.0 149.35.19.

Possible settings are: Enabled - The port will receive and forward packets. This is the default setting. Disabled - The port will not receive or forward packets.
AT-S45 User’s Guide Enabled - Flow control for both packets entering and leaving the port. Configuration changes are immediately activated on a port.
Chapter 5 Port Security This chapter contains the procedures for setting port security. The sections in this chapter include: ❑ Port Security Overview on page 57 ❑ Configuring Port Security on page 58 ❑ Configuring the Limited Security Mode on page 60 Note Port security does not apply to ports on GBIC modules in an AT-9410GB switch.
AT-S45 User’s Guide Port Security Overview The port security feature can enhance the security of your network. You can use the feature to control the number of MAC addresses learned on the ports, and so control the number of network devices that can forward frames through the switch. There are four levels of port security. The security level can be set on a per port basis. Normal This operating mode disables port security.
AT-S45 User’s Guide Configuring Port Security To set a switch’s port security level, perform the following procedure: 1. From the Main Menu, type A to select Advanced Switch Configuration. 2. From the Advanced Switch Configuration Menu, type P to select Port Security Configuration. The Port Security Configuration Menu in Figure 16 is displayed.

Chapter 6 Port Trunking This chapter contains the procedures for creating and deleting port trunks.
AT-S45 User’s Guide Port Trunking Overview Port trunking is an economical way for you to increase the bandwidth between an AT-9410GB Gigabit Ethernet Switch and another network device, such as a server, router, workstation, or another switch. A port trunk is two or more data ports that have been grouped together to increase the bandwidth between a switch and a network node by functioning as one logical path.
AT-S45 User’s Guide maintain the order of the port connections, you would connect port 2 on the first AT-9410GB switch to port 1 on the second AT-9410GB, port 3 to port 2, and so on. ❑ The ports of a port trunk must be of the same type. For example, they can be all twisted pair ports or all fiber optic ports. ❑ You can create a port trunk of the GBIC modules installed in the GBIC1 and GBIC2 slots, provided that the GBIC modules are of the same type.
AT-S45 User’s Guide Creating a Port Trunk This section contains the procedure for creating a port trunk on the switch. Be sure to review the guidelines in Port Trunking Overview on page 63 before performing the procedure. Caution Do not connect the cables to the trunk ports on the switch until after you have configured the trunk with the management software. Connecting the cables before configuring the software will create a loop in your network topology.
AT-S45 User’s Guide Figure 20 Trunking Configuration Menu 3. Type A to select Add Trunk Member. The following prompt is displayed. Enter trunk group number> Trunk group is in the range from 1 to 4 4.

Refer to the instructions included with the node for directions on how to create a port trunk. 10. Connect the cables to the ports of the trunk on the switch. The port trunk is ready for network operations.
AT-S45 User’s Guide Deleting a Port Trunk Caution Disconnect the cables from the port trunk on the switch before performing the following procedure. Deleting a port trunk without first disconnecting the cables can create loops in your network topology. Data loops can result in broadcast storms and poor network performance. To delete a port trunk from the switch, perform the following procedure: 1. From the Main Menu, type A to select Advanced Switch Configuration. 2.
Chapter 7 Port Monitoring This chapter contains the procedures for creating and deleting a port monitor.
AT-S45 User’s Guide Port Monitoring Overview The port monitoring feature allows you to unobtrusively monitor the traffic being received and transmitted on a port on a switch by having the traffic copied to another switch port. You can connect a network analyzer to the port where the traffic is being copied and monitor the traffic on the other port without impacting network performance or speed.
AT-S45 User’s Guide Creating a Port Monitor To create a port monitor, perform the following procedure: 1. From the Main Menu, type A to select Switch Advanced Configuration. 2. From the Switch Advanced Configuration Menu, type M to select Port Monitoring Configuration Menu. The Port Monitoring Configuration Menu in Figure 22 is displayed.

Chapter 8 Spanning Tree Protocol This chapter provides introductory information on the Spanning Tree Protocol (STP) and explains how to adjust the STP bridge and port parameters. The sections in this chapter include: ❑ STP Overview on page 75 ❑ Configuring a Bridge’s STP Settings on page 78 ❑ Configuring STP Port Settings on page 81 Note For detailed information on the Spanning Tree Protocol, refer to Section 4 of IEEE Std 802.1D, ISO/IEC 10038: 1993.
AT-S45 User’s Guide STP Overview The AT-9410GB Gigabit Ethernet Switch supports the Spanning Tree Protocol, as specified in the IEEE 802.1D standard. STP can be an important part of large networks where loops, either planned or unplanned, exist in the network topology. A loop exists when two or more nodes on your network can transmit data to each other over more than one data link. A network loop can pose a danger to network performance and operability.
AT-S45 User’s Guide Finding and Resolving Redundant Paths Once the Root Bridge has been selected, the bridges must determine if the network contains redundant paths and, if one is found, they must select a preferred path while placing the redundant paths in a backup or blocking state.
AT-S45 User’s Guide Handling 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. It might take time for the root bridge to notify all bridges that a topology change has occurred, especially if it is a large network.
AT-S45 User’s Guide Configuring a Bridge’s STP Settings This section contains the procedure for configuring a bridge’s STP settings. Caution STP on a bridge is disabled by default. If you enable STP, the bridge provides default STP parameters that are adequate for most networks. Changing them without prior experience and an understanding of how STP works might have a negative effect on your network. You should consult the IEEE 802.1d standard before changing any of the STP parameters. 1.
AT-S45 User’s Guide The window displays the current STP operating parameters in two columns labeled Designated Root and Bridge ID. The column labeled Designated Root displays the STP parameters from the root bridge. The parameters in the Bridge ID column are from the AT-9410GB switch you are currently managing. 3. Adjust the bridge STP settings as needed. The commands for setting the parameters are described below. Enable/Disable [S]TP Enables and disables STP on the switch.
AT-S45 User’s Guide Set Bridge Forwarding [D]elay Sets the waiting period before a bridge changes to a new state, for example, from blocking to forwarding. If the bridge transitions too soon, not all links may have yet adapted to the change, resulting in network loops. The default is 15 seconds. Spanning Tree [P]ort Configuration Configures Port Priority, Path Cost, Trunk Priority, and Trunk Path Cost. This procedure is explained in Configuring STP Port Settings on page 81.
AT-S45 User’s Guide Configuring STP Port Settings To configure STP port parameters, perform the following procedure: 1. From the Main Menu, type B to select Basic Switch Configuration. 2. From the Basic Switch Configuration Menu, type S to select Spanning Tree Configuration. 3. From the Spanning Tree Configuration menu, type P to select Spanning Tree Port Configuration. The STP Port Configuration Menu in Figure 24 is displayed.
AT-S45 User’s Guide Set Path [C]ost Sets the cost parameter used in deciding which port provides the lowest cost path to the root bridge for that LAN. The default value is 4. The range is 1 to 65535. Set [T]runk Priority Sets the parameter used as a tie breaker when two or more trunk groups are determined to have equal costs to the root bridge. The default value for priority is 128. The range is 0-255.
AT-S45 User’s Guide MAC Address The MAC addresses of the ports on the switch.
Chapter 9 Virtual LANs This chapter contains basic information about virtual LANs (VLANs). It also contains the procedures for creating, modifying, and deleting VLANs from a local or Telnet management session.
AT-S45 User’s Guide 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 broadcast 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 management software and so be able to group nodes with related functions into their own separate, logical LAN segments.
AT-S45 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-S45 management software. VLAN memberships can be changed any time through the management software without moving the workstations physically, or having to change group memberships by moving cables from one switch port to another. Additionally, a virtual LAN can span more than one switch.
AT-S45 User’s Guide Tagged and Untagged VLAN Overview As explained in the VLAN Overview section earlier in this chapter, a VLAN consists of a group of ports on one or more Ethernet switches that forms a logical Ethernet segment and an independent broadcast 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.
AT-S45 User’s Guide Untagged and Tagged Ports There are two kinds of ports that you can assign to an IEEE 802.1Qcompliant VLAN: tagged ports and untagged ports. The basic different between the two is that an untagged port can be a member of only one VLAN at a time while a tagged port can be a member of multiple VLANs. Untagged Ports When the ports on an Ethernet switch are divided into independent VLANs, the switch needs a mechanism for determining which ports belong to which VLANs.
AT-S45 User’s Guide with tagged ports, explained next, where VLAN membership is determined by information within the frames themselves.) Frames received on untagged ports and lacking any VLAN identifying information are referred to as untagged frames. When a switch receives a frame on an untagged port, it first examines the PVID of the port on which the frame was received and then adds the PVID to the frame itself. It then examines the destination MAC address of the frame.
AT-S45 User’s Guide Tagged VLANs are also useful where multiple VLANs span across switches. You can use one port per switch for connecting all VLANs on the switch to another switch. The IEEE 802.1Q standard deals with how this tagging information is used to forward the traffic throughout the switch. The handling of frames tagged with VIDs coming into a port is straightforward.
AT-S45 User’s Guide Creating a Tagged or Untagged VLAN The procedure for creating a new VLAN is divided into the following phases: ❑ Phase 1: Assigning a VID and name and specifying the port members ❑ Phase 2: Converting tagged ports into untagged ports Performing Phase 1 is required whenever you create a new VLAN. Every VLAN must have a name, VID, and, of course, ports. You will need to perform Phase 2 if some or all of the ports of a VLAN will be untagged ports.
AT-S45 User’s Guide Note It is a good idea to check the VLAN Type field in the window to make sure it is set to 802.1Q, which happens to be the default. You can create tagged and untagged VLANs only when the switch is operating in the 802.1Q mode. For instructions on how to change the switch’s VLAN mode, see Setting the VLAN Type on page 109. 3. From the VLAN Management Menu, select C for Create VLAN. The VLAN Creation Menu in Figure 30 is displayed.
AT-S45 User’s Guide If this VLAN will be part of a larger VLAN that spans multiple switches, than the VID value for the VLAN should be the same on each switch.

The following prompt is displayed: Enter VLAN Name ->Enter VLAN Name > 7. Enter a VLAN name of up to 32 characters.
AT-S45 User’s Guide Phase 2 This phase of creating a new VLAN converts the tagged ports that you added to the new VLAN into untagged ports. This involves changing the PVIDs of the ports so that they match the VID of the new VLAN. For example, if you assigned the new VLAN a VID of 4, you must change the PVIDs of the untagged ports to 4. The following procedure explains how this is accomplished. The following procedure assumes that you are continuing directly from Phase 1. 1.
AT-S45 User’s Guide The following prompt is displayed: Set PVID->Enter port number> 4. Enter the port number whose PVID you want to change. A prompt similar to the following is displayed: Enter PVID for port 1> 5. Enter the new PVID for the port. Once a new PVID has been assigned to a port, the port is removed as an untagged port from its current VLAN and added to the new VLAN as an untagged port. If the port is also an tagged member of any VLANs, it remains as a tagged member of those VLANs. 6.
AT-S45 User’s Guide Viewing or Modifying a Tagged or Untagged VLAN There are two phases to modifying a VLAN. You might need to perform both phases or just one, depending on what it is you want to change in the VLAN.

AT-S45 User’s Guide Configuring a Bridge’s STP Settings Caution STP on a bridge is disabled by default. If you enable STP, the bridge provides default STP parameters that are adequate for most networks. Changing them without prior experience and an understanding of how STP works might have a negative effect on your network. You should consult the IEEE 802.1d standard before changing any of the STP parameters. To configure a bridge’s STP parameters, perform the following procedure: 1.
AT-S45 User’s Guide Enable/Disable STP Enables and disables STP on the switch. The default setting is disabled. Bridge Priority The priority number for the bridge. This number is used in determining the root bridge for STP. The bridge with the lowest priority number is selected as the root bridge. If two or more bridges have the same priority value, the bridge with the numerically lowest MAC address becomes the root bridge.
AT-S45 User’s Guide Configuring STP Port Settings To display and configure the STP port settings, perform the following procedure: 1. From the Home page, click on Basic Config., Spanning Tree and then STP Port Config. from the sub-menu. The Spanning Tree Port Configuration window in Figure 66 is displayed.

Path Cost The spanning tree algorithm uses the cost parameter to decide which port provides the lowest cost path to the root bridge for that LAN. The default values for this parameter are 100 for a 10 Mbps port, 10 for a 100 Mbps port, and 4 for a 1 Gbps port. The range is 1 to 65535. This following information is for display purposes only and cannot be changed from the Spanning Tree Port Configuration Menu.
Chapter 23 Virtual LANs This chapter explains how to create, modify, and delete VLANs from a web management session. Note For background information on VLANs, refer to Chapter 9, Virtual LANs.
AT-S45 User’s Guide Creating a Tagged or Untagged VLAN The procedure for creating a new VLAN is divided into the following phases: ❑ Phase 1: Assigning a VID and name and specifying the port members ❑ Phase 2: Converting tagged ports into untagged ports Performing Phase 1 is required whenever you create a new VLAN. Every VLAN must have a name, VID, and, of course, ports. You will need to perform Phase 2 if some or all of the ports of a VLAN will be untagged ports.
AT-S45 User’s Guide Note Check the VLAN Type field in the window to make sure it is set to 802.1Q, which happens to be the default. You can create tagged and untagged VLANs only when the switch is operating in the 802.1Q mode. For instructions on how to change the switch’s VLAN mode, refer to Setting the VLAN Type on page 209. 2. Enter a VLAN ID in the VLAN ID field. If this VLAN will be unique in your network, then its VID must also be unique from all other VIDs in the network.
AT-S45 User’s Guide However, it is important to note that, by default, all of the ports that you just added to the new VLAN are tagged ports, meaning they are shared ports. The ports are still members of their current VLANs. If you want to convert the ports into untagged ports, you must perform the procedure in Phase 2. Note There are two additional buttons in the bottom right-hand corner of the page. The Restore button will cancel any changes you have made to the VLAN since using the Apply button.
AT-S45 User’s Guide The VLAN Port Config page will appear, as displayed in Figure 68 Figure 68 VLAN Port Configuration This window lists the ports on the switch and each port’s current PVID assignment. For example, referring to the figure above, Ports 5 to 12 all have a PVID of 1, meaning that they are untagged members of the Default VLAN, which has a VID of 1. 2. Enter a PVID value in the PVID field for the port number whose PVID you want to change.
AT-S45 User’s Guide Viewing or Modifying a Tagged or Untagged VLAN There are two phases to modifying a VLAN. You might need to perform both phases or just one, depending on what it is you want to change in the VLAN. The phases are: ❑ Phase 1: In this phase, you can view a VLAN’s configuration, as well as change a VLAN’s name and add or remove tagged ports. ❑ Phase 2: In this phase, you can add or remove untagged ports. Phase 1 This phase explains how to display the Config VLAN Member Menu of a VLAN.
AT-S45 User’s Guide The VLAN Create/Modify (802.1Q VLANs) in Figure 70 is displayed. Figure 70 VLAN Create/Modify (802.1Q VLANs) The rows on the page are defined below: Tagged A dot in a radio button indicates the corresponding port is a tagged member of the VLAN. For example, referring to the figure above, ports 9 and 10 on the master switch are tagged members of the VLAN. Untagged A ‘U’ for a port indicates that the port is an untagged member of the VLAN.
AT-S45 User’s Guide Note You cannot add untagged ports to a VLAN from this window. To add untagged ports, refer to Phase 2, below. 4. If you want to remove a tagged port from the VLAN, click the Not Member radio button of the appropriate port. Note You cannot remove untagged ports from a VLAN from this window. To remove untagged ports, refer to Phase 2, below. 5.
AT-S45 User’s Guide Phase 2 You must perform this phase whenever you need to add or remove an untagged port from a VLAN. This phase explains how to change the PVIDs of the ports so that they match the VID of a different VLAN. For example, if you want to assign Port 2 as an untagged member of a VLAN with a VID of 4, you must change the PVID of the port to 4. 1. Click on the Advanced Config menu tab and select VLAN Config from the sub-menu. Select VLAN Port Config from the next submenu.
AT-S45 User’s Guide For example, if you wanted to make Port 4 an untagged port of a VLAN with a VID of 7, you would change the PVID for Port 4 to the value 7. 3. Click the Apply button. Once a new PVID has been assigned to a port, the port is removed as an untagged port from its current VLAN and added to the other VLAN as an untagged port. If the port is also an tagged member of any VLANs, it remains as a tagged member of those VLANs. 4.
