Catalyst 2900 Series XL Switches and Modules

Upgrading to a New Release

This section describes the procedure for upgrading your switch software by using the Cisco IOS command-line interface (CLI). If you are running Cisco IOS Release 11.2(8)SA3, we recommend that you upgrade the switch by using the web-based Cisco Visual Switch Manager Software.

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

The upgrade procedure consists of the following major steps:

Step 1 Downloading the Cisco IOS image and Switch Manager HTML files from CCO to your workstation.

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 to upgrade your switch to the new image and HTML files.

Downloading Files from CCO

Follow these steps to download a new version of Catalyst 2900 series XL software and the TFTP server application.

Step 1 Enter the following URL in your browser Go To or Location field:
http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL

Step 2 Login to Software Center if prompted.

Step 3 Download the Cisco IOS image. The file names for the Cisco IOS image files follow these conventions:

•Enterprise Edition Software: c2900XL-hs-mz

•Standard edition software: c2900XL-h-mz

Step 4 Download the HTML tar file: c2900XL-html.tar.

Note   You can also download the supplied TFTP server from this URL. The readme.txt file describes how to download the TFTP server.

Upgrading Switch Software by Using the CLI

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

The procedure that follows includes the commands to address the following issues:

•Because the switch Flash memory can hold only one software image file, you need to change the name of the current image file to the name of the new file you are copying. You then replace the old file with the new file when you copy it into Flash memory.

•To avoid a conflict with users accessing the manager software pages during the software upgrade, you need to delete the existing HTML files and disable access to the HTML pages before you upgrade the software.

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 files to a TFTP server to which you have access.

Step 2 You can 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 
Config file:       flash:config.text 
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. The file named c2900XL-h-mz_current_version is your current image file.

Step 6 Rename the current image file to the name of the new image. This does not affect the operation of the switch. 

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

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

-rwx       80971   Sep 14 1998 03:10:38  c2900XL-diag-mz-112.0.0.11-SA2 
-rwx        4800   Mar 01 1993 00:04:14  html 
-rwx         159   Jan 01 1970 00:00:34  env_vars 
-rwx        1121   Mar 01 1993 18:46:01  config.text

Step 8 If you are upgrading a WS-C2908-XL, WS-C2924-XL, WS-C2924C-XL, or WS-C2916M-XL, you need to delete the diagnostics file to make room for the new image.

Note   If you are not upgrading one of the listed model numbers, you do not need to delete this file.

The diagnostics file has a name in the following format: c2900XL-diag-mz-version_name. The string version_name depends on the switch and software you are running.

Display the diagnostics file: 

switch# dir flash:c2900XL-diag-mz* 
Directory of flash:

-rwx 80971 Sep 14 1998 03:10:38 c2900XL-diag-mz-112.0.0.11-SA2

Delete the diagnostics file: 

Switch# del flash:c2900XL-diag-mz-112.0.0.11-SA2

Delete filename [c2900XL-diag-mz-112.0.0.11-SA2]?

Delete flash:c2900XL-diag-mz-112.0.0.11-SA2? [confirm]

Switch#

Step 9 Enter terminal configuration mode: 

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

Step 10 Disable access to the switch HTML pages: 

switch(config)# no IP http server

Step 11 Change the name of the default image file: 

switch(config)# boot system flash:new_image

Step 12 Return to privileged EXEC mode: 

switch(config)# end

Step 13 Verify that the name of the default image file is correct: 

switch# show boot 
BOOT path-list:    flash:new_image 
Config file:       flash:config.text 
Enable Break:      1 
Manual Boot:       no 
HELPER path-list:  
NVRAM/Config file 
buffer size: 32768

Step 14 Use the name of the new image file when you copy it from the TFTP server to the Flash memory: 

switch# copy tftp://server_ip_address//path/new_image flash:new_image 
Source IP address or hostname [server_ip_address]?  
Source filename [path/filename]?  
Destination filename [flash:new_image]?  
Loading /path/filename.bin from server_ip_address (via!) 
[OK - 843975 bytes]

Step 15 Remove the manager software HTML files: 

switch# del flash:html/*.*

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

Step 16 If you are running Cisco IOS Release 11.2(8)SA3 or later, remove the files in the Snmp directory: 

switch# del flash:html/Snmp/*.*

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

Step 17 If you are running Cisco IOS Release 11.2(8)SA2 or earlier, create a directory on the switch Flash memory to be used for the HTML files: 

switch# mkdir flash:html/Snmp

Make sure the "S" in "Snmp" is uppercase.

Step 18 Enter the following command to copy the HTML file from the TFTP server to the switch Flash memory: 

switch# tar /x tftp://server_ip_address//path/filename.tar flash:html

Loading /path/filename.tar from server_ip_address (via!) 
extracting advanced.gif (2648 bytes) 
extracting amber.gif (530 bytes)! 
extracting bar.gif (4156 bytes)! 
extracting cool.gif (530 bytes) 
extracting daytona.gif (1470 bytes) 
extracting duplgnd.gif (639 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 19 Enter terminal configuration mode: 

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

Step 20 Reenable access to the switch HTTP pages: 

switch(config)# IP http server

Step 21 Return to privileged EXEC mode: 

switch(config)# end

Step 22 Reload the new software with the following command: 

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

Step 23 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

Limitations and Restrictions

This section should be reviewed before you begin working with the Catalyst 2900 series XL switches or Catalyst 2900 series XL modules. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

Multi-VLAN Port Functionality

The multi-VLAN port functionality is currently not supported by Cisco IOS Release 11.2(8)SA4 on the following devices:

•Catalyst 2924-XL-A

•Catalyst 2924-XL-EN

•Catalyst 2924C-XL-A

•Catalyst 2924C-XL-EN

•Catalyst 2912-XL-A

•Catalyst 2912-XL-EN

•Catalyst 2912MF-XL

•Catalyst 2924M-XL-A

•Catalyst 2924M-XL-EN

•WS-X2914-XL (4-port, 10TX/100TX module)

•WS-X2922-XL (2-port, 100BaseFX module)

•WS-X2924-XL (4-port, 100 BaseFX module)

This functionality will be supported in a future release of the switch software.

Support for Five Devices in Switch Network View

The Switch Network View application can display up to five Catalyst 2900 series XL switches in a stack under the following conditions:

•The primary switch must be a Catalyst 2916M-XL series.

•The remaining switches must be Catalyst 2924-XL or Catalyst 2924C-XL switches.

•The primary switch must be running Cisco IOS Release 11.2(8)SA4.

Caution   If you use the network view to display more than four switches and they are not configured according to these guidelines, the fifth switch might not display properly.

Gigabit Ethernet Connectivity

The Catalyst 2900 series XL does not support Gigabit Ethernet with this software release. Gigabit Ethernet connectivity will be available in the future.

IEEE 802.1Q Tagging

The Catalyst 2900 series XL Cisco IOS 11.2(8)SA4 release does not support IEEE 802.1Q trunking. This feature will be enabled with a future software release.

ISL Trunking Interoperability

ISL connectivity between a Catalyst 2900 series XL switch and the WS-X5225R or WS-X5201R line cards requires a minimum hardware revision of 1.3 on the WS-X5225R or WS-X5201R line cards. Revision 1.3 hardware will be available by Dec 31, 1998. (CSCdk28747)

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 to set a value greater than this new range in a previous release and upgrade your software to version Cisco IOS 11.2(8)SA4, the switch sets this value to the default: 20 seconds for IEEE STP, 15 seconds for DEC STP, and 10 seconds for IBM STP.

Current Caveats

This section describes possibly unexpected behavior by Cisco IOS Release 11.2(8)SA4.

•If VTP pruning is enabled and a trunk port is shut down or has no link, the VTP pruning join-transmitted counter might increase erroneously.

Ignore this counter value when the trunk port is shut down or has no link. (CSCdk45332)

•If your switch is configured with close to the maximum number of supported VLANs (64), multiple trunks, or trunk port groups, the following behavior can occur:

•Sluggishness in the user interface during system startup and when the configuration changes.

•CPUHOG message on the CLI interface such as the following: 

Mar  1 00:04:12: %SYS-3-CPUHOG: Task ran for 2099 msec (60/52),

Process = xxxxxx, PC = 12CA64

-Traceback= 12C89C 12CA68 1C8C94 1D0ECC 1D1EDC 1C7600 1C78F0

This does not affect normal switch operation and performance. (CSCdk57517)

•When a Catalyst 2900 series XL trunk is connected to a VTP v1-only device, such as a Catalyst 1900 or 2820, you might see the VTP revision error count increase erroneously on both switches. This does not affect VTP functionality.

Ignore this counter value in this situation. (CSCdk58875)

•VTP traps specified in the CISCO-VTP-MIB are not supported in Release 11.2(8)SA4.

You can use the CLI or SNMP to monitor VTP error counters. (CSCdk61632)

•Cisco IOS Release 11.2(8)SA4 allows secure addresses to be defined without checking to see if the port is defined as a dynamic access port.

To work around this problem, do not define secure addresses on dynamic access ports, and remove any secure addresses from a port before reconfiguring it as a dynamic access port. (CSCdk61650)

•If there is a change in configuration or link status on a port while incoming broadcast traffic is blocked by broadcast storm control, forwarding of broadcast packets to the port remains blocked even after the normal forwarding of broadcast packets resumes.

If this problem occurs, disconnect and reconnect the cable plugged into the port to restart broadcast forwarding. (CSCdk67149)

•When the configuration of VTP pruning mode changes (via CLI or SNMP or received VTP advertisements), the following message can display. 

Error message %SW_VLAN-4-BAD_VLAN_TIMER_ACTIVE_VALUE:  encountered

No workaround is necessary. This message does not affect switch operation. (CSCdk70408)

•The no vmps retry and no vmps reconfirm configuration commands do not work as expected in Cisco IOS Release 11.2(8)SA4.

To work around this, use the commands without the no prefix and explicitly enter the default values (vmps retry 3 and vmps reconfirm 60) to get the default settings. (CSCdk72786)

•Frames received and dropped on a trunk port that is blocked by Spanning-Tree Protocol are sometimes incorrectly counted as FCS errors.

Ignore this counter value when a trunk port is blocked by STP. (CSCdk61602)

Cisco IOS 11.2(8)SA3 Caveats/Release 11.2(8)SA4 Modifications

This section describes Cisco IOS Release 11.2(8)SA3 caveats that were resolved with Cisco IOS Release 11.2(8)SA4.

•When the switch receives a STP topology change notification, the Cisco Group Management Protocol (CGMP) tables should be purged for the virtual LAN (VLAN) in which it was received.

If an incorrect topology is maintained in the CGMP tables, the entry or entries can be cleared with the command clear cgmp [vlan vlan-id] group [group-mac-address]. This will cause CGMP to relearn the latest topology. To view the CGMP tables, use the show cgmp command. [CSCdk31459]

•If you use Visual Switch Manager to change the STP protocol setting to IBM or DEC, the protocol setting does not take effect. To change the STP protocol setting to IBM or DEC, use the CLI. [CSCdk42398]

•If SNMP is used to change an STP parameter, the change takes effect but is lost when the system is rebooted. The workaround is to use the command line interface to change STP parameters. [CSCdk42666]
