These release notes describe the limitations, restrictions and caveats of Cisco IOS Release 11.2(8)SA4.
Catalyst 2900 series XL switches are supported by a special release of Cisco IOS software that is not released on the same eight-week maintenance cycle that is used for other platforms. As maintenance releases and future Cisco IOS releases become available, they will be posted to CCO in the
Cisco IOS software area.
These release notes contain the following topics:
Table 1 lists the Catalyst 2900 series XL switches and modules and the Cisco IOS software that they support.

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.
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.
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/cgi-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:
Step 4 Download the HTML tar file: c2900XL-html.tar.
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:
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.
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.
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.
The multi-VLAN port functionality is currently not supported by Cisco IOS Release 11.2(8)SA4 on the following devices:
This functionality will be supported in a future release of the switch software.
The Switch Network View application can display up to five Catalyst 2900 series XL switches in a stack under the following conditions:
 | 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. |
The Catalyst 2900 series XL does not support Gigabit Ethernet with this software release. Gigabit Ethernet connectivity will be available in the future.
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 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)
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.
This section describes possibly unexpected behavior by Cisco IOS Release 11.2(8)SA4.
