3 Microsoft Internet Explorer is not supported on Solaris 2.5.1 or higher.
Note
To access CMS, follow the procedures in the "Initial Switch Configuration" section.
Cluster Requirements and Guidelines
When creating a switch cluster, we recommend that the highest-end, command-capable switch in the cluster be the command switch and that the command switch has the latest software version installed. If there are switches in the cluster with older software versions, they should all be upgraded to the latest software version. All switches in the same platform should be upgraded to the latest software version.
Table 6 lists the cluster capabilities and minimum software versions for the switches. The switches are listed in the order of highest- to lowest-end switch. A lower-end switch cannot be the command switch of a switch listed above it in the table (for example, a Catalyst 2900 XL switch cannot be the command switch of a cluster that has Catalyst 3550 switches.)

1 Catalyst 2900 XL (4-MB) switches appear in the front-panel and topology views of CMS. However, CMS does not support configuration or monitoring of these switches.
Some versions of the Catalyst 2900 XL software do not support clustering, and if you have a cluster with switches that are running different versions of Cisco IOS software, software features added on the latest release might not be reflected on switches running the older versions. For example, if you start Visual Switch Manager (VSM) on a Catalyst 2900 XL switch running Cisco IOS Release 11.2(8)SA6, the windows and functionality can be different from a switch running Cisco IOS Release 12.0(5)WC(1) or later.

Initial Switch Configuration
This section provides these procedures:
•
•
•
This section assumes that you have already installed the switch and connected devices to it, as described in the switch hardware installation guide.
Using the Setup Program
You can use an automatic setup program to assign switch IP information, host and cluster names, and passwords and to create a default configuration for continued operation. Later, you can use CMS or the command-line interface (CLI) to customize your configuration. To run the setup program, access the switch from the PC terminal that you connected to the console port. For information about connecting a PC or terminal to the switch console port, refer to the switch hardware installation guide.
Note
The first time that you access the switch, it runs a setup program that prompts you for IP and other configuration information necessary for the switch to communicate with local routers and the Internet. This information is also required if you plan to use CMS to configure and manage the switch.
You will need the following information from your system administrator:
Use this procedure to create an initial configuration for the switch:

Guidelines for Upgrading Switch Software
When upgrading the switch software, follow these rules:
•
•
•

•
•
•
Overview of the Switch Upgrade Process
The software upgrade procedure has these major steps:
•
•
The tar command extracts the Cisco IOS image and the CMS files from the .tar file during the TFTP copy to the switch.
•
When you upgrade a switch, the switch continues to operate while the new software is copied to Flash memory. If Flash memory has enough space, the new image is copied to the selected switch but does not replace the running image until you reboot the switch.
Note
If Flash memory does not have enough space for two images, your new image is copied over the existing one.
Note
•
–
–
Features provided by the new software are not available until you reload the switch.
Determining the Switch Software Version
The Cisco IOS image is stored as a .bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the CMS files needed for web management. The image is stored on the system board Flash device (flash:).
You can use the show version user EXEC command to see the software version that is running on your switch. For example:
Switch> show versionCisco Internetwork Operating System SoftwareIOS (tm) C3500xl Software (C3500xl-C3H2S-M), Version 12.0(0.0.2)WC5, RELEASE SOFT)Copyright (c) 1986-2002 by cisco Systems, Inc.Compiled Tue 14-May-02 12:57 by userameImage text-base: 0x00003000, data-base: 0x0034A3B8You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that might be stored in Flash memory.
Note
Which Software Files to Download from Cisco.com
New software releases are posted on Cisco.com and are also available through authorized resellers. From Cisco.com, you can also download a TFTP server application to copy the switch software from your PC to the switch.
Table 8 describes the file extensions and what they mean for the upgrade procedure. Table 9 lists the software files that you need from Cisco.com.
Downloading the New Software and TFTP Server Application to Your
This procedure is for copying the combined .tar file to the Catalyst 2900 XL or Catalyst 3500 XL switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.
Note
Follow these steps to download the software and, if necessary, the TFTP server application, from Cisco.com to your management station:
Step 1
Step 2
•
http://www.cisco.com/public/sw-center/sw-lan.shtml
•
http://www.cisco.com/public/sw-center/sw-lan.shtml
To download the files, select Catalyst 2900XL Software, Catalyst 2900 LRE XL Software, or Catalyst 3500XL Software.
Step 3
The readme.txt file describes how to download the TFTP server application. New features provided by the software are not available until you reload the software.
Copying the Current Startup Configuration from the Switch to a PC or Server
When you make changes to a switch configuration, your changes become part of the running configuration. When you enter the command to save those changes to the startup configuration, the switch copies the configuration to the config.text file in Flash memory. To ensure that you can recreate the configuration if a switch fails, you might want to copy the config.text file from the switch to a PC or server.
The following procedure requires a configured TFTP server such as the Cisco TFTP server available on Cisco.com.
Beginning in privileged EXEC mode, follow these steps to copy a switch configuration file to the PC or server that has the TFTP server application:
Step 1
switch# copy flash:config.text tftpStep 2
Address or name of remote host []? ip_addressStep 3
Destination filename [config.text]? yes/noStep 4
Upgrading the Switch
This section provides these topics about upgrading the switch:

•
•
Using CMS to Upgrade One or More Switches
You can use the Software Upgrade window in Cluster Manager to upgrade all or some of the switches in a cluster at once. Consider these conditions when doing an upgrade:
•
–
–
•
Follow these steps to use CMS to upgrade switch software. Refer to the online help for more details.
Step 1
Step 2
You can enter just the filename or a pathname into the New Image File Names field. You do not need to enter a pathname if the image file is in the directory that you have defined as the TFTP root directory.
Note
Note
On the Catalyst 2900 XL and Catalyst 3500 XL switches, new images are copied to Flash memory and do not affect operation. The switch checks Flash memory to ensure that there is sufficient space before the upgrade takes place. If there is enough space, the new image is copied to the switch without replacing the old image, and after the new image is completely downloaded, the old one is erased. In this case, you can still reboot your switch by using the old image if a failure occurs during the copy process.
If there is not enough space in Flash memory for the new and old images, the old image is deleted, and the new image is downloaded.
On the Catalyst 1900 and Catalyst 2820 switches, the new image overwrites the current image during the upgrade.
Note
Recovering from an Incomplete CMS Software Upgrade
An upgrade failure can create multiple copies of Cisco IOS images and other files in Flash memory. This would not leave enough space for the CMS files to also be copied to Flash memory; thus, you will not be able to access the switch through CMS.
If a failure occurs, ensure that the image file in Flash memory has the same name as the contents of the boot variable:
•
•
If the contents of the boot variable and the image file name are the same, the switch can reset successfully. If they are different, rename the image file, or reset the boot variable by entering the system boot name global configuration command. The boot variable and the image file name should be the same.
To recover from the incomplete download of the CMS files, log in to the switch, and upgrade the software as described in the "Using the CLI to Upgrade Member Switches" section.
Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch
If you are upgrading a Catalyst 2900 XL switch that is not an LRE switch, see the "Recovering from an Incomplete CMS Software Upgrade" section.
Follow these steps to upgrade the LRE switch software:

Upgrading LRE Firmware
The 2900 LRE XL switch can store and properly apply LRE binaries if there are updates required to the firmware on the switch local LRE controllers or connected CPE devices.
Other upgrade-related features include:
•
•
Note
You perform an upgrade with this command:
hw-module slot x upgrade lre [force][local lo n | remote lo x/y]
Automatic upgrading is not supported. You can upgrade in one of these ways:
•
•
•
Note
Configuring for an LRE Upgrade
In the absence of any LRE Upgrade configurations, the LRE upgrade attempts to upgrade all local LRE controllers and CPE devices to the most recent compatible versions of the LRE binaries required for each LRE target device. LRE upgrade configurations should rarely be required. The primary purpose of LRE upgrade configuration commands is to provide for downgrades of LRE binaries.
If you wish to override the switch automatic selection of LRE binaries, you have two methods available:
•
•
You can use config global commands to specify the LRE binary or binaries for a specified target type. (A target type is the family [and optionally the model or model revision] of a device containing one or more upgradable hardware elements.) A target can be a local LRE controller on the switch or a remote CPE device.
You can perform global LRE upgrade configurations by entering LRE upgrade controller configuration commands from the controller configuration submode. Use the upgrade configuration command in the controller submode to override the system default selection of an LRE binary to be applied on a particular remote CPE device or local LRE controller. Controller configurations take precedence over global upgrade configurations.
The preserve keyword causes the LRE upgrade mechanism to not upgrade the local controller on which preserve is configured or any of the CPE devices connected to that controller. If you want to preserve (in other words, not upgrade) some of the CPE devices connected to a particular controller but allow upgrades to others, you can enter controller upgrade configuration commands for the links that you want to upgrade.
The no form of the upgrade command removes the command for applying a particular LRE binary. To resume default upgrade behavior for a given controller, configure the no upgrade commands on that controller.
Note
Note
See the reference pages for the upgrade commands in the Catalyst 2900 XL and Catalyst 3500 XL Command Reference for further details.

You can upgrade either on a system-wide basis (in other words, upgrading the software on all connected CPE devices and local LRE chipsets) or on individual CPE device or LRE controllers. By default, a system-wide upgrade applies the most recent versions of LRE binaries that are most compatible with each upgradable hardware module. The system-wide upgrade method is the one that you use in almost all situations.
When executing upgrades, you can elect to upgrade a single CPE device or local controller by using this command hw-module slot <x> upgrade lre [local lo n | remote lo x/y]. If no local or remote option is given, a system-wide upgrade is performed.
Global Configuration of LRE Upgrades
Beginning in privileged EXEC mode, follow these steps to perform a system-wide upgrade to configure the LRE binary to apply to a target device and upgradable hardware element combination:
Note
Controller Configuration of LRE Upgrades
Beginning in privileged EXEC mode, follow these steps to explicitly direct the LRE binaries to be applied to either the local controller or a specific VDSL link:
You can use the upgrade configuration command in the controller submode to override the system default selection of an LRE binary that will be applied on either end of a particular LRE link. Controller configurations take precedence over global upgrade configurations.
The preserve keyword causes the LRE upgrade mechanism to not upgrade the local controller on which preserve is configured or any of the CPE devices connected to that controller. If you want to preserve (in other words, not upgrade) some of the CPE devices connected to a particular controller but allow upgrades to others, you can enter controller upgrade configuration commands for the links you want to upgrade.
The no form of the command removes the command for applying a particular LRE binary. To resume default upgrade behavior for a given controller, do not configure the custom upgrade commands on that controller.
LRE Upgrade Behavior Details
You see on the console screen when you start an upgrade:
Switch>enSwitch#hw-module slot 0 upgrade lreYou are about to start an LRE upgrade on all LRE interfaces.Users on LRE links being upgraded will experience a temporary disruption of Ethernet connectivity.Start LRE upgrade ? [yes]:If you answer yes or press the Enter key, the upgrade starts. If you answer no, you get the EXEC prompt.
You can expect this link behavior of the CPE device during an upgrade:

•
The workaround, if you do not want to disable the proxy server settings on the browser, is to download a browser from a different vendor and use it without the proxy server settings configured to access the CMS.
LRE Restrictions
These are the LRE restrictions for this release:
•
Data transmission continues normally if the LRE link is restored. (CSCdt22573)
•
Note
The workaround is to set the LRE interface to the LRE-10 or the LRE-10LL profile. (CSCdv01167)
•
switch(config)#int longReachEthernet 0/?
<1-28> LongReachEthernet interface number
The correct range is:
<1-24> LongReachEthernet interface number
The workaround is to only use ports 1 through 24. (CSCdz78081)

Note
Open Caveats
These are the open caveats for this release.
•
When a switch assigns a VLAN ID to an Intel Pro 10/100 S Management Adapter network interface card (NIC), the NIC might not re-establish a link after it resets. The switch is working correctly. The failure is caused by the NIC dropping the link after it resets.
The workaround is to enter the shut and no shut interface configuration commands on the interface.This restores the link to the NIC.
•
The output of the show running configuration and show mac-address-table user EXEC commands might appear differently depending on the order in which you enter the mac-address-table static global configuration commands.
There is no workaround. This does not affect the functionality of the switch.
•
In some network topologies, a switch fails and stops adding VLANS to the allowed list after you enter the switchport trunk allow vlan all interface configuration command.
There is no workaround.
Resolved Caveats
These caveats were resolved in this release:
•
•
•
Resolved Cisco IOS Caveats
These Cisco IOS caveats were resolved in this release:
•
Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected. A workaround is available.
Cisco has made software available, free of charge, to correct the problem.

http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml
•
A switch now correctly responds to the switchport trunk allowed vlan remove interface configuration command.
•
When UDLD aggressive mode is enabled on a port that belongs to an access VLAN other than VLAN1, that port is no longer erroneously shut down when you enter the shut and no shut interface configuration commands or reload the switch.
•
When Terminal Access Controller Access Control System Plus (TACACS+) authentication fails and authentication, authorization, and accounting (AAA) is configured on a switch, this traceback message is no longer generated:
%AAAA-3-INVSTATE: unknown AUTHOR/CMD: Internal state is invalid: astruct 0x706928 ustruct 0x0 -Traceback= 1370A4 136F80 172064 172ED0 17EB70 1E9230
•
A speed mismatch error no longer occurs on a Catalyst 3534-PWR XL switch port under these conditions:
–
–
–
•
The neighboring-state information of an adjacent switch is now shown correctly regardless of the order in which UniDirectional Link Detection (UDLD) is enabled.
•
The udld message time global configuration command now works correctly. In previous releases, this command only worked if you entered it on a port that was in VLAN1.
•
UDLD has been re-enabled for 10/100 Ethernet (copper) ports:

Resolved CMS Caveats
These CMS caveats were resolved in this release:
•
When an ATM module is installed in a Catalyst 2912 MF switch, this error message no longer when you open the Voice VLAN dialog window:
ArrayIndexOutOfBoundsExceptionResolved LRE Caveats
These LRE caveats were resolved in this release:
•
When STP is configured on a FastEthernet port, it no longer takes up to 10 seconds for the port to achieve an STP forwarding state after the switch powers on or reboots.
•
A switch now sends coldStart and warmStart SNMP traps when it is reloaded or powered up.

Corrections to Software Configuration Guide
These are corrections for the software configuration guide:
This information was not included in the software configuration guide for this release.
•
Error Message LRE_UPGRADE-4-INIT_RESOURCE: cannot locate lre firmware filesExplanation This message means that the LRE upgrade module cannot locate a required resource. The LRE upgrade module requires a directory in Flash memory named flash:/lre-bin. This directory stores the LRE-related firmware files for the LRE switch and LRE CPE devices. The upgrade module cannot initialize unless a directory already exists in Flash memory.
Recommended Action Verify that the flash:/lre-bin directory exists. If the directory is missing, create an empty directory named flash:/lre-bin. If the directory already exists, report this message to your Cisco technical support representative. (CSCdz56235, CSCdz85180)
For more information about system messages, refer to the "System Messages" chapter of the Catalyst 2900 XL and Catalyst 3500 XL Software Configuration Guide.
•
When you start the switch, the switch automatically requests configuration information from a DHCP server only if a configuration file is not present on the switch.
DHCP autoconfiguration does not occur under these conditions:

•
•
By default, a trunk port sends to and receives traffic from all VLANs in the VLAN database. If the switch is configured with a number of VLANs and it is connected to Cisco IP Phones through 802.1Q trunk ports, the switch sends spanning-tree BPDUs for all VLANs to all of the phones. This can flood the phones with traffic
Beginning in privileged EXEC mode, follow these steps to configure a VLAN list that allows only voice and data VLANs on the trunk port:
