Release 11.2(8.5)SA6 Modifications

This section describes new features in IOS Release 11.2(8.5)SA6 and IOS Release 11.2(8.2) caveats that are resolved in IOS Release 11.2(8.5)SA6.

•LED indications for power-on self-test (POST) failures are different in this release. If a port fails a test, the port LED and the system LED turn amber and remain amber. In previous releases, only LEDs of failed linked ports remained amber.

•A new command has been added in this release. You can use the CLI show post command to determine if a switch or port has passed POST.

•When a 4-MB Catalyst 2900 XL switch is added to a cluster, reloading the switch by a soft reset or power recycling no longer brings down the switch. [CSCdm94877]

•When a port is changed from a multi-VLAN port to an access port, there is no longer a possible loss of connectivity. [CSCdm72514]

•The privileged EXEC mode config clock summer-time recurring command no longer resets the switch. [CSCdm94936]

Release 11.2(8.2)SA6 Modifications

This section describes IOS Release 11.2(8.1) caveats that were resolved with IOS Release 11.2(8.2)SA6.

•When using the GigaStack GBIC with a 3500 XL switch or 2900 XL modular switch and IOS Release 11.2(8.1)SA6, you could experience a problem with traffic flow in one direction when you insert a cable. This potential problem has been resolved in this release. [CSCdm40538]

•The configure overwrite-network command, when issued, no longer overwrites the configuration file with gibberish. [CSCdm24149]

Changes Since IOS Release 11.2(8)SA5

This IOS release supports the creation of a cluster of up to 16 switches through the HTML-based Cluster Management tools. You create a cluster by assigning an IP address to a command switch, which can then connect to up to 15 member switches. The command switch can then manage communication between the member switches and the management interfaces. Cluster members must be running IOS Release 11.2(8.1)SA6 or later.

Cluster Management features include a map of the cluster devices and links, single- and multiple-port configuration, and device reports. In addition, you can use the command switch to upgrade multiple switches to new software releases.

All 3500 XL switches can be command switches. The 8-MB 2900 XL switches can be upgraded to act as command switches. The 4-MB 2900 XL switches cannot be upgraded to be command switches.

Increased Number of VLANs

On some switches, the maximum number of supported VLANs has increased from 64 to 250. See the tables in the "Hardware and Supporting Software" section to identify these platforms.

TACACS+

TACACS+, an Enterprise Edition Software feature, provides the means to manage network security from a server. You can configure the TACACS+ server to perform switch authentication, authorization, and accounting. Authentication is the action of determining who the user is and whether he or she is allowed to access the switch. Authorization is the action of determining what the user is allowed to do on the system, and accounting is the action of collecting data related to resource usage.

The original edition software for 4-MB switches does not support TACACS+.

Note   TACACS+ does not manage access authentication for CVSM. The switch enable password is used.

STP UplinkFast

STP UplinkFast, an Enterprise Edition Software feature, is an enhancement to Spanning-Tree Protocol (STP) that accelerates the choice of a new root port when a link or switch fails or when STP reconfigures itself. When UplinkFast is enabled, the status of the root port changes to forwarding immediately without going through the listening and learning states.

The original edition software for 4-MB switches does not support STP UplinkFast.

Network Time Protocol

The Network Time Protocol (NTP) controls how a switch receives time information from an external source. This IOS release supports the configuration of switches to act as an NTP client—requesting timing information from an NTP server—or as an NTP broadcast client—receiving time broadcasts from an NTP broadcast server, such as a router.

The original edition software for 4-MB switches does not support NTP.

Catalyst 3500 Series XL Switch Support

IOS Release 11.2(8.1)SA6 or later supports three new 3500 XL switches. As with the 2900 XL switches, you can order these switches with either the standard edition software or the Enterprise Edition Software.

lists the different port densities of the 3500 XL models. See the "Related Documentation" section for the complete list of 3500 XL documentation.

Changes to the Documentation Set

Because of the addition of the 3500 XL switches, the documentation set for IOS Release 11.2(8.1)SA6 or later changed substantially. In general, the hardware documentation has been separated from the software documentation, and the online help system for the HTML interfaces has been expanded to include all the how-to procedures for network and device management.

Limitations and Restrictions

This section should be reviewed before you begin working with the switches. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

Connecting to the 600W Cisco Redundant Power System

The following restrictions apply to using the 600W Cisco Redundant Power System (RPS) with a 2900 or 3500 XL switch:

•Do not connect a switch power cord to an AC outlet if the switch is also connected to a powered-up RPS.

•The switches do not support the fully-redundant or redundant-with-reboot configurations that are described in the Cisco RPS Hardware Installation Guide. These configurations should not be used with Catalyst 2900 or 3500 XL switches.

The Cisco RPS can provide a quasi-redundant power source for four external devices that use up to 150W DC each. You can use a one-to-one cable (one connector at each cable end) to connect four external devices to the four DC output power modules. The power source is quasi-redundant because there are two AC input power modules for the Cisco RPS and one DC output power module for each external device. The AC input to the Cisco RPS is fully redundant, but the DC output to the external devices is not.

Cluster Management Link Report

The link report in Cluster Management is no longer supported. The documentation and help might refer to the link report, but it is no longer part of the product.

TACACS+ and CVSM

TACACS+ does not manage access authentication for Cisco Visual Switch Manager (CVSM). The switch enable password is used.

Hot-Swapping Not Supported for ATM and Gigabit Ethernet Modules

A Catalyst 2900 XL switch must be turned off before you can insert one of the following modules:

•Catalyst 2900 series XL 1000BaseX modules

•Catalyst 2900 series XL ATM modules

Port Configuration Conflicts

Certain combinations of port features create configuration conflicts (see ). For example, the network port floods all unknown unicast and multicast packets to a port; therefore, port security, which limits traffic on a port, cannot be enabled on the network port. If you try to enable incompatible features, CVSM issues a warning message and prevents you from making the change. Reload the page to refresh CVSM. In , no means that the two referenced features are not compatible.

IEEE 802.1Q Configuration Considerations

IEEE 802.Q trunks impose some limitations on the trunking strategy for a network. The following restrictions apply to IEEE 802.1Q trunks:

•Make sure the native VLAN for an IEEE 802.1Q trunk is the same on both ends of the trunk link. If the native VLAN on one end of the trunk is different from the native VLAN on the other end, spanning-tree loops might result.

•Disabling STP on the native VLAN of an IEEE 802.1Q trunk without disabling STP on every VLAN in the network can potentially cause STP loops. We recommend that you either leave STP enabled on the native VLAN of an IEEE 802.1Q trunk or disable STP on every VLAN in the network. Make sure your network is loop-free before disabling STP.

Spanning-Tree Maximum Age Command

The range of seconds for the span-tree max-age command is now 6 to 200 seconds. If you use this command in a previous release to set a value greater than this new range and then upgrade your software to IOS Release 11.2(8.1)SA6 or later, the switch sets this value to the default: 20 seconds for IEEE STP, 15 seconds for DEC STP, and 10 seconds for IBM STP.

Compatibility with the CiscoWorks2000 RME Suite

When using the Software Image Management (SWIM) application in the Resource Manager Essentials (RME) suite of CiscoWorks2000 product family to perform automated system software and boot loader upgrades, you should note the following:

•Catalyst 2900 series XL switches require IOS Release ll.2(8)SA4 or later and RME version 2.1 or 2.2.

•Catalyst 3500 series XL switches require IOS Release 11.2(8.1)SA6 or later and RME version 2.2.

Upgrading to a New Software Release

This section describes the procedure for upgrading your switch software by using the IOS command-line interface (CLI).

Caution   There are separate procedures for upgrading 4-MB and 8-MB Catalyst 2900 series XL switches. Please review the two procedures before starting the upgrade. Both procedures include a step for determining the amount of memory that a switch has.

If you are running IOS Release 11.2(8)SA3 or later, we recommend that you upgrade the switch by using the web-based CVSM. Instructions for upgrading through CVSM are in the Catalyst 2900 Series XL Installation and Configuration Guide, or, for this IOS release, the Cisco IOS Desktop Switching Software Configuration Guide.

Note   You cannot use the web-based interface to upgrade a switch running IOS Release 11.2(8)SA2 or previous releases. Use the CLI to perform the upgrade in such cases.

The CLI upgrade procedure consists of the following major steps:

Step 1 Downloading the combined .tar file from CCO. This file contains the IOS image and the HTML files. The tar command extracts the IOS image and the HTML files from the combined .tar file during the TFTP copy to the switch.

Step 2 If necessary, downloading the TFTP server application to copy the switch software from your PC to the switch.

Step 3 Using the CLI or CVSM to upgrade your switch to the new software.

Which Files to Use

Review and before you download the software. describes the file extensions and what they mean for the upgrade procedure. In general, it is easier to upgrade the switch software by using a combined .tar file that contains the HTML files and the IOS image. The upgrade procedures in these release notes describe how to use a combined .tar file, and you must use a combined .tar file to upgrade a switch through the switch HTML interfaces.

describes the various versions of the software that can be downloaded. Each IOS version can support command-switch or member-switch capabilities.The software files for this IOS release are listed by switch in and .

Table 7 Possible Extensions for IOS Software Files

Extension
Description

.tar

Downloading the New Software

Follow these steps to download a new version of IOS 11.2(8.5)SA6 software and, if necessary, the TFTP server application.

Step 1 Use to to identify the files that you want to download.

Note   It is recommended that you download the combined .tar file that contains the image file and the HTML files. The procedures in these release notes are for upgrading a switch by using a combined .tar file, and the web-based CVSM interface is designed to upgrade a switch by using this combined file.

Step 2 Registered users can download files from the following locations:

•For 2900 XL switches, enter the following URL in your browser Go To or Location field:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL

•For 3500 XL switches, enter the following URL in your browser Go To or Location field:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat3500XL

Non-registered users can download files from the following locations:

•For 2900 XL switches:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL

•For 3500 XL switches:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat3500XL

Step 3 Download the IOS file or files.

Step 4 Download the TFTP server from this URL, if necessary. The readme.txt file describes how to download the TFTP server.

After you have downloaded the correct file to your PC or workstation, you can use the CLI to perform a TFTP transfer of the file or files to the switch.

Upgrading Catalyst 3500 Series XL Switches

This procedure is only for upgrading 3500 XL switches by copying the combined .tar file to the switch. You copy the files to the switch from a TFTP server and extract the files by entering the tar command.

Note   If you want to copy the IOS image file or HTML files separately to the switch, follow the upgrade procedure in the release notes that came with your switch, or refer to the 2900 XL documentation for IOS Release 11.2(8)SA4 on CCO.

Follow these steps to upgrade the switch software by using a TFTP transfer:

Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the console port via the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command: 

server% telnet switch_ip_address

Step 3 Enter privileged EXEC mode: 

switch> enable 
switch#

Step 4 Display the name of the current (default) image file. The following example shows the current name in italic: 

switch# show boot 
BOOT path-list:    flash:current_image

Enable Break:      1 
Manual Boot:       no 
HELPER path-list:  
NVRAM/Config file 
buffer size: 32768

Step 5 If there is no file defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory.

Step 6 Using the name of the combined .tar file that you downloaded, rename the current image file to that name, and replace the .tar extension with .bin. The current image filename is then the same as the downloaded filename but with a .bin extension. This step does not affect the operation of the switch. 

switch# rename flash:current_image flash:new_image.bin 
Source filename [current_image]?  
Destination filename [new_image]?

For example: 

switch# rename c2900XL-hs-mz-112.8-SA4.bin c2900XL-c3h2s-mz-112.8.5-SA6.bin

Step 7 Display the contents of Flash memory to verify the renaming of the file: 

switch# dir flash: 
Directory of flash: 
-rwx       910426   Mar 06 1993 23:47:28  new_image.bin

-rwx       80971   Sep 14 1998 03:10:38  c3500XL-diag-mz-112.0.0.11-SA6

-rwx         159   Jan 01 1970 00:00:34  env_vars 
-rwx        1121   Mar 01 1993 18:46:01  config.text

Step 8 Enter global configuration mode: 

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z.

Step 9 Disable access to the switch HTML pages: 

switch(config)# no IP http server

Step 10 If you entered the boot command with the name of the image file, enter this command to change it to the new name. 

switch(config)# boot system flash:new_image.bin

Note   If you have not entered the boot command with the name of the image, you do not need to enter this command; the switch automatically finds the correct file to use when it resets.

Step 11 Return to privileged EXEC mode: 

switch(config)# end

Step 12 Remove the CVSM HTML files: 

switch# delete flash:html/*

Press Enter to confirm the deletion of each file. Do not press any other keys during this process.

Step 13 Remove the files in the Snmp directory: 

switch# delete flash:html/Snmp/*

Make sure the S in Snmp is uppercase.

Press Enter to confirm the deletion of each file. Do not press any other keys during this process.

Caution   In the following step, the tar command copies the combined .tar file that contains both the image and the HTML files. You do not need to copy an HTML.tar file in this procedure.

Step 14 Enter the following command to copy the new image and HTML files to the switch Flash memory: 

switch# tar /x tftp://server_ip_address//path/filename.tar flash: 
Loading /path/filename.tar from server_ip_address (via VLAN1):!) 
extracting info (110 bytes)

extracting html/ieGraph.html.gz (553 bytes)

extracting html/DrawGraph.html.gz (760 bytes)

extracting html/GraphFrame.html.gz (774 bytes)!

. . .

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.

Step 15 Enter global configuration mode: 

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z.

Step 16 Re-enable access to the switch HTTP pages: 

switch(config)# IP http server

Step 17 Return to privileged EXEC mode: 

switch(config)# end

Step 18 Reload the new software with the following command: 

switch# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm]

Step 19 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

Step 20 After the switch reboots, you can Telnet back into the switch and enter the show version command in privileged EXEC mode to verify the upgrade procedure.

Upgrading 4-MB Catalyst 2900 Series XL Switches

This procedure is for upgrading the 4-MB switches that run the original edition of IOS
Release 11.2(8.5)SA6. The 4-MB models that run the original edition software are WS-C2908-XL, WS-C2924-XL, WS-C2924C-XL, and WS-C2916M-XL. You upgrade the switches by extracting the IOS image file and the HTML files from a combined .tar file. You copy the files to the switch from a TFTP server and extract the files by entering the tar command.

Note   If you want to copy the IOS image file or HTML files separately to the switch, follow the upgrade procedure in the release notes that came with your switch, or refer to the Catalyst 2900 series XL release notes for IOS Release 11.2(8)SA4 on CCO.

If you are unsure whether your switch has 4 MB or 8 MB of memory, you can verify memory capacity at Step 4.

Follow these steps to upgrade the switch software by using the tar command and a TFTP transfer:

Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the console port via the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command: 

server% telnet switch_ip_address

Step 3 Enter privileged EXEC mode: 

switch> enable 
switch#

Step 4 Confirm that you have a 4-MB switch: 

switch# show version

Current Caveats

This section describes possible unexpected activity by IOS Release 11.2(8.5)SA6.

•When you try to access a switch by entering the IP address in the location field while using CVSM, the switch displays the Cisco Access page for the new switch. However, you cannot access CVSM for the new switch from this page. The switch refreshes the Cisco Access page without displaying the switch home page.

The workaround is to start a new browser session and enter the IP address of the new switch in the Location field of the new browser session. (CSCdm27401)

•When upgrading a switch from the CVSM System page, the switch renames the existing filename even if Retain Current IOS Image File Name field is selected. After the upgrade, the image is not changed to the current image name.

The workaround is to delete the current IOS image before the upgrade so that the new image file can be renamed correctly. (CSCdm32685)

•If you use Telnet or a browser to access a member switch without an IP address from the CVSM CDP page, the switch starts a session with the command switch.

The workaround for Telnet is to first display the cluster-member number by entering the privileged EXEC command show cluster member. Note the number of the member you want to access, and then Telnet to the switch by entering the following command: rcommand switch_number.

The workaround for the browser is to start Cluster Management from the switch home page and start Cluster Manager. Right-click on the chassis of the switch that you want to access, and select Switch Manager. (CSCdm34868)

•The Device Report and Bandwidth Graph menu items for candidate switches without IP addresses do not work.

The workaround is to add candidates to the cluster and then right-click the device and select Device Report or Bandwidth Graph from the pop-up menu. (CSCdm31724)

•The Link Graph between members and non-members does not work.

The workaround is to display the Device Report for the member switch, select Port Information from the drop-down menu in the right corner of the page, and click the appropriate port. Click Graph. (CSCdm32226)

•Adding trap managers using the SNMP Manager dialog box in Cluster Manager only adds the trap managers to the command switch, and it does not propagate them to cluster members. As a result, only traps that are generated by the command switch are received by the trap managers.

The workaround is to add the trap managers for the member switches by using the CVSM SNMP Configuration page. This must be done for every member in the cluster. Note that if the member switches do not have assigned IP addresses, you need to assign unique community strings for each trap manager. The community strings are the only means for determining which switch generated the trap. (CSCdm32763)

•Device reports and graphs give "SNMP Unavailable" messages.

First make sure that the switch is reachable via the network and that the SNMP agent is enabled. Also verify that you are using the correct community string. There should be only one read-only SNMP community string. If you change the community string while using cluster manager or CVSM, you must reload your browser to display the changes. (CSCdm32367)

•Links between members sometimes do not display in Cluster Builder or Cluster View.

The workaround is to display the Device Links Report from the Cluster Builder window. (CSCdm27668)

•Link Graphs for the Catalyst 3512 XL and Catalyst 3524 XL do not work.

The workaround is to right-click the switch icon, select Device Report from the pop-up menu, and select Port Information from the drop-down menu. Click the appropriate port, and click Graph. (CSCdm35346)

•Some dialog boxes in the Cluster Management application do not appear properly formatted in Solaris.

Use Windows 95, Windows 98, or Windows NT to avoid this problem. (CSCdm23953)

•In Internet Explorer 5.0, the tab key does not work properly. It does not highlight the editable fields as it should.

Use the mouse to click on the field, or use Netscape 4.5, Netscape 4.5.1, or Internet Explorer 4.01. (CSCdm24761)

•When using Internet Explorer 5.0 and CVSM to change the configuration, the changes are not updated by the browser but are applied to the switch.

The workaround is to click the browser Refresh button to display the new settings. (CSCdm27546)

•IP access lists can interfere with creating clusters. If you filter VTY connections based on an IP access list, clustering can fail, and users cannot use the privileged EXEC mode rcommand to access a member switch CLI.

The workaround is to not use access lists if you want to cluster switches. The access class 199 that is created when a device is configured as the command switch is an exception. (CSCdm39364)

•If you enter the interface configuration mode no ip address command to remove the IP address from a member switch, it disables the switch IP protocol stack.

The workaround is to enter the EXEC mode clear ip address vlan 1 command instead. (CSCdm39373)

•Network Address Translation (NAT) commands are added to the configuration file of a command switch when a cluster is created.

No workaround is necessary, but the commands should not be removed. (CSCdm39380)

•A laptop computer that goes to sleep while it has an open serial port session to a Catalyst 3500 series XL switch can cause the switch to reset when the laptop wakes up.

The workaround is to disconnect the serial cable from the console port when it is not in use. (CSCdm37220)

•When you configure more than 64 VLANs and you do not save the running configuration, the switch can assign STP instances to the wrong VLANs the next time it reloads.

If you configure more than 64 VLANs on a 2900 or 3500 XL switch, enter a privileged EXEC save running-config command after exiting VLAN configuration mode. (CSCdm33358)

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
