Upgrading to a New Software 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 or later, we recommend that you upgrade the switch by using the web-based Cisco Visual Switch Manager Software (CVSM). Instructions for upgrading via CVSM are in the Catalyst 2900 Series XL Installation and Configuration Guide.
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 CLI upgrade procedure consists of the following major steps:
Step 1
Downloading the software file from CCO.
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.
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/public/sw-center/switching/cat2900XL.shtml
From this page you can select to download the Enterprise Edition Software, the standard edition software, or previous releases of software.
Step 2
Login to Software Center if prompted and select the software option you want.
If you do not have an account for Software Center, you can dowload IOS 11.2(8)SA5 standard edition software from the following URL:
http://www.cisco.com/public/sw-center/switching/cat2900XL-form.shtml
You are prompted to complete a survey before you download the software.
Step 3
Download the Cisco IOS file. The files follow these naming conventions:
•
Enterprise Edition Software: c2900XL-hs-mz-112.8-SAn.tar
•
Standard edition software: c2900XL-h-mz-112.8-SAn.tar
Step 4
Download the TFTP server from this URL, if necessary. The readme.txt file describes how to download the TFTP server.
Upgrading Switch Software by Using the CLI
After you have downloaded the new file 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 CVSM 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 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_addressStep 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: 32768Step 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
Using the name of the tar file that you downloaded, rename the current image file to that name. The new image file name is then the same as the file name that you downloaded 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]?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.textStep 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 software.
Note
If you are not upgrading one of the listed models, 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-SA2Delete 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 serverStep 11
Change the name of the default image file:
switch(config)# boot system flash:new_imageStep 12
Return to privileged EXEC mode:
switch(config)# endStep 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: 32768Step 14
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 15
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/*.*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 16
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/SnmpMake sure the "S" in "Snmp" is uppercase.
Step 17
Enter the following command to copy the new software file 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!) 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 18
Enter terminal configuration mode:
switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z.Step 19
Reenable access to the switch HTTP pages:
switch(config)# IP http serverStep 20
Return to privileged EXEC mode:
switch(config)# endStep 21
Reload the new software with the following command:
switch# reload System configuration has been modified. Save? [yes/no]:y Proceed with reload? [confirm]Step 22
Press Return to confirm the reload.
Your Telnet session ends when the switch resets.
Upgrading the Switch Software by Using IOS 11.2(8)SA5 Cisco Visual Switch Manager
This section describes the procedure for upgrading switch software after you have upgraded to IOS Release 11.2(8)SA5. To upgrade to IOS Release 11.2(8)SA5, see the "Upgrading to a New Software Release" section. To upgrade the following models from IOS Release 11.2(8)SA4 to IOS Release 11.2(8)SA5, you need to use the command-line interface procedure described in the "Upgrading Switch Software by Using the CLI" section:
•
WS-C2908-XL
•
WS-C2924-XL
•
WS-C2924C-XL
•
WS-C2916M-XL
With IOS Release 11.2(8)SA5, you can upgrade the switch software by using a single file. You can download this file by using the procedure described in "Downloading Files from CCO" section.
Follow these steps to upgrade the switch software by using the combined (tar) file that contains the image and the HTML pages:
Step 1
Open the CVSM System Configuration page.
Note
To avoid errors during the upgrade process, close any other switch CVSM pages open.
Step 2
In the Combined Cisco IOS and Visual Switch Manager Upgrade section, enter the IP address of your TFTP server in the Server IP Address or Name of TFTP Server field.
Step 3
In the Cisco IOS and Visual Switch Manager Upgrade Filename field, enter the filename of the combined IOS image and HTML tar file that you downloaded from CCO (such as c2900XL-h-mz-112.8-SA5.tar or c2900XL-hs-mz-112.8-SA5.tar)
Note
Do not enter the path name. Enter only the filename in this field. You set the path in the TFTP root directory of the TFTP server application.
Step 4
Click Upgrade Cisco IOS and Visual Switch Manager.
In the CVSM software message window that appears, click OK to change the old image filename into the new image filename. Changing the filenames enables the old image to be overwritten by the new version. Only enough Flash memory is available for one version.
Step 5
In the CVSM software confirmation window that appears, click OK to continue the upgrade process. This can take several minutes.
Step 6
In the TFTP server window, wait for the successful message to appear.
Step 7
Reboot the switch.
Step 8
Reload the CVSM page to access the new HTML files.
New Features Added for this Release
IOS Release 11.2(8)SA5 includes support for the following new modules:
•
Catalyst 2900 Series XL ATM Module
•
Catalyst 2900 Series XL Gigabit Ethernet Module
The documentation for these modules is listed in the "Related Documentation" section.
IOS Command Changes
Several IOS commands have changed to support the ATM and Gigabit Ethernet modules. The ATM commands will be documented in the Configuration Notes for Cisco IOS Release 11.2(8)SA5 and posted on CCO with the Catalyst 2900 series XL ATM module documentation.
The Catalyst 2900 Series Command Reference describes the commands that refer to the Catalyst 2900 Series XL Gigabit Ethernet module.
One command supporting the Gigabit Ethernet module is described in the section flowcontrol.
flowcontrol
Use the flowcontrol interface configuration command on Gigabit Ethernet ports to control traffic rates during congestion. Use the no form of this command to disable flow control on the port.

Switch(config-if)# flowcontrol asymmetricLimitations 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.
Limitations Removed Since Last Release
The following limitations that existed in IOS 11.2(8)SA4 have been removed:
•
Any port can be a multi-VLAN port.
•
IEEE 802.1Q tagging is supported.
•
Gigabit Ethernet connectivity is supported.
Hot-Swapping Not Supported on ATM and Gigabit Ethernet Modules
A Catalyst 2900 series XL switch must be turned off before you can insert one of the following modules:
•
Catalyst 2900 series XL Gigabit Ethernet module
•
Catalyst 2900 series XL ATM module
In addition the following commands are not supported:
•
hw-module n stop
•
hw-mod restart
Mixed 10/100 and Gigabit Ethernet Port Groups
You can create EtherChannel port groups that consist of Gigabit ports or of 10/100 ports but not both at the same time. Port groups with a mixture of Gigabit Ethernet ports and 10/100 ports are not supported.
Changes to CVSM
In CVSM, the following fields on the Port Configuration page have been changed for this release:
Gigabit Ethernet Autonegotiation Mismatches
When a 10/100 port fails to match the duplex setting of an attached device, it can reduce performance or cause link errors. When a Gigabit Ethernet port fails to match the settings of an attached device, the link does not come up, and no statistics are generated.
Setting the STP Path Cost for an ATM Module
For the path cost parameter, enter a number from 1 to 655535. The default value for Catalyst 2900 series XL ATM Module ports (155 Mbps) is 14.
Assigning ATM Ports to VLANs
You can use the command-line interface (CLI) of the ATM module to map the LAN emulation (LANE) client to a VLAN or bind one or more permanent virtual connections (PVCs) to a VLAN. The VLAN ID is then displayed in the Assigned VLANs column of the VLAN membership page.
In the standard edition version of IOS 11.2(8)SA5, an ATM port is always a static-access port. In Enterprise Edition Software, an ATM port is always a trunk port.
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, the manager software issues a warning message and prevents you from making the change. Reload the page to refresh the manager software. 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 when using 802.1Q trunks:
•
Make sure the native VLAN for an 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 leave STP enabled on the native VLAN of an 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 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.
Using BOOTP to Assign IP Address Information
You can use BOOTP to assign IP information to a Catalyst 2900 series XL switch. A database with a list of physical MAC addresses and corresponding IP addresses must be set up on the BOOTP server. Other information, such as the corresponding subnet masks and default gateway addresses can also be stored in the database but are optional. The switch must be able to access the BOOTP server through one of its ports.
If the switch starts and no IP address has been assigned, it transmits a BOOTP broadcast request to all of its ports having a physical connection, requesting a mapping for its physical MAC address. A valid response includes the IP address, which is mandatory, and the subnet mask and the default gateway, which are optional.
The reception of a valid BOOTP response immediately activates the rest of the system protocol suite, without requiring a system reset. The running configuration is set, but the saved configuration in Flash memory is not automatically updated. To save the IP information in the saved-configuration file, log in to the command-line interface and enter the write memory command. The IP information is then preserved, and the switch does not issue BOOTP messages the next time it resets.
Current Caveats
This section describes possibly unexpected behavior by Cisco IOS Release 11.2(8)SA5.
•
If a 4-Mb DRAM switch (Catalyst 2908 XL, 2916M XL, 2924 XL, or 2924C XL) learns 2048 addresses, has 64 VLANs, and has 5 or more trunk ports, the following message appears on the console when CVSM is in use:
%SYS-2-MALLOCFAIL: Memory allocation of 1680 bytes failed from 0x1071C8, pool I/O, alignment 0The workaround is to either not use the CVSM or to change the configuration by reducing the number of addresses in use, the number of VLANs, or the number of trunk ports. (CSCdk87690)
•
If a monitor port is not monitoring port Fa0/1, the monitor port will still receive the Cisco Discovery Protocol (CDP) and BPDU packets sent to port Fa0/1. This happens when the monitor port is monitoring VLAN 1.
There is no work around for this bug. (CSCdk88060)
•
If a switch is configured to get its IP address from a BOOTP server, dynamic access ports will not be assigned to a VLAN. As a result, dynamic access ports cannot be used on a switch that is configured to get its IP address from a BOOTP server.
To workaround this problem: Either configure an IP address on the switch, or do not use dynamic access ports on the switch. (CSCdk93323)
•
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)
•
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. (CSCdk45332)
Cisco IOS 11.2(8)SA4 Caveats/Release 11.2(8)SA5 Modifications
This section describes IOS Release 11.2(8)SA4 caveats that were resolved with IOS Release 11.2(8)SA5.
•
When a Catalyst 2900 XL trunk is connected to a Virtual Trunk Protocol (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. (CSCdk58875)
•
VTP traps specified in the CISCO-VTP-MIB are not supported in IOS Release 11.2(8)SA4. (CSCdk61632)
•
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. (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. (CSCdk67149)
•
When the configuration of VTP pruning mode changes (via CLI or SNMP or received VTP advertisements), the following message might display. (CSCdk70408)
Error message %SW_VLAN-4-BAD_VLAN_TIMER_ACTIVE_VALUE: encountered•
The no vmps retry and no vmps reconfirm configuration commands do not work as expected in Cisco IOS Release 11.2(8)SA4. (CSCdk72786)
