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.
The following restrictions apply to using the 600W Cisco Redundant Power System (RPS) with a Catalyst 2900 XL switch:
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.
A Catalyst 2900 XL switch must be turned off before you can insert one of the following modules:
Certain combinations of port features create configuration conflicts (see Table 4). 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 Table 4, No means that the two referenced features are not compatible.
| ATM Port1 | Port Group | Port Security | Monitor Port | Multi-VLAN Port | Network Port2 | Connect to Cluster? | |
|---|---|---|---|---|---|---|---|
| ATM port | - | No | No | No | No | No | Yes |
| Port group | No | - | No | No | Yes | Yes | Yes |
| Port security | No | No | - | No | No | No | Yes |
| Monitor port | No | No | No | - | No | No | Yes |
| Multi-VLAN port | No | Yes | No | No | - | Yes | Yes |
| Network port | No | Yes (only source-based group) | No | No | Yes | - | No |
| Connect to cluster | Yes | Yes | Yes | Yes | Yes | No | - |
| 1Catalyst 2900 series XL switches only 2A network port cannot connect cluster members to the command switch. |
IEEE 802.Q trunks impose some limitations on the trunking strategy for a network. The following restrictions apply to IEEE 802.1Q trunks:
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.
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, Catalyst 2900 series XL switches require IOS Release ll.2(8)SA4 or later and RME version 2.1 or 2.2.
This section describes the procedure for upgrading your switch software by using the IOS command-line interface (CLI).
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 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.
Review Table 5 and Table 6 before you download the software. Table 5 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.
Table 6 lists the file names for the 4-MB original edition software. Original edition software is Enterprise Edition Software that runs on the following 4-MB switch models: WS-C2908-XL, WS-C2924-XL, WS-C2924C-XL, or WS-C2916M-XL. Original edition software does not support TACACS+, STP UplinkFast, or NTP. This software enables the switch to act as a cluster member switch only, not a commander switch.
| Extension | Description |
.tar | A compacted file from which you can extract files by using the tar command. There are two types of .tar files:
|
.bin | The IOS image file that you can copy to the switch through TFTP. |
| Filename | Description | CCO Location 1 |
c2900XL-hs-mz-112.8.6-SA6.bin | Original edition IOS image-only file | Registered and public |
c2900XL-hs-mz-112.8.6-SA6.tar | Original edition IOS image and HTML files | Registered and public |
| 1Software files are available through both a registered site, for which you must register to have access, and a public site for which there are no restrictions. |
Follow these steps to download a new version of IOS 11.2(8.6)SA6 software and, if necessary, the TFTP server application.
|
Note We recommend 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 Download files from the following locations:
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.
This procedure is for upgrading the 4-MB switches that run IOS Release 11.2(8.2)SA6 original edition software. 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 CCO for the Catalyst 2900 series XL release notes for IOS Release 11.2(8)SA4. |
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 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 Cisco Internetwork Operating System Software IOS (tm) C2900XL Software (C2900XL-HS-M), Version 11.2(0.0.65)SA2, Copyright (c) 1986-1999 by cisco Systems, Inc. Compiled Fri 09-Apr-98 13:55 by jchristy Image text-base: 0x00003000, data-base: 0x0020C740 ROM: Bootstrap program is C2900XL boot loader pacifica-165 uptime is 1 day, 20 hours, 5 minutes System restarted by reload System image file is "flash:c2900XL-hs-mz-112.0.0.65-SA6.bin", booted via cisco WS-C2924C-XL (PowerPC403GA) processor (revision 0x11) with 4096K/640K bytes of memory. Processor board ID 0x09, with hardware revision 0x00
Step 5 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.bin
Config file: flash:config.text
Enable Break: 1
Manual Boot: no
HELPER path-list:
NVRAM/Config file
buffer size: 32768
Step 6 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 7 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 a .bin extension. The current image file name is then the same as the downloaded file name but with a .bin extension. This step does not affect the operation of the switch.
switch# rename flash:current_image.bin flash:new_image.bin
Source filename [current_image]?
Destination filename [new_image]?
For example:
switch# rename flash:c2900XL-hs-mz-112.8-SA4.bin flash:c2900XL-hs-mz-112.8.6-SA6.bin
Source filename [c2900XL-hs-mz-112.8-SA6.bin]? Destination filename [c2900XL-hs-mz-112.8.6-SA6.bin]?
switch#
Step 8 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 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 9 If a file starting with the character string c2900XL-diag-mz appears in the Flash directory, you should remove it. This 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# delete 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 10 Enter global configuration mode:
switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 11 Disable access to the switch HTML pages:
switch(config)# no IP http server
Step 12 Change the name of the default image file:
switch(config)# boot system flash:new_image.bin
Step 13 Return to privileged EXEC mode:
switch(config)# end
Step 14 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 15 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 16 If you are running IOS Release 11.2(8)SA3 or later, 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.
Step 17 If you are running IOS Release 11.2(8)SA2 or previous releases, 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.
 |
Caution In the following step, the tar command copies to the switch 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 18 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 c2900XL-c3h2s-mz-112.0.66-SA6.bin (1271095 bytes)!!!!!!!!!!!!!!!!!!!! html/ (directory) extracting html/Detective.html.gz (1134 bytes)! extracting html/ieGraph.html.gz (553 bytes) extracting html/DrawGraph.html.gz (760 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 global configuration mode:
switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 20 Re-enable 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.
Step 24 After the switch reboots, you can use Telnet to go back into the switch and enter the show version command in privileged EXEC mode to verify the upgrade procedure.
