These release notes describe the caveats for the Catalyst 2900 series XL Asynchronous Transfer Mode (ATM) modules.
These release notes contain the following topics:
The ATM modules work with modular Catalyst 2900 XL switches that use firmware version 11.2(8)SA5 or above. You can check the installed firmware version by using the switch firmware. For firmware upgrade procedures, refer to the Cisco IOS Desktop Switching Software Configuration Guide. You can access this document on Cisco Connection Online (CCO).
 |
Note The Catalyst 2900 series XL ATM modules can be installed only in a Catalyst 2900 series switch. |
Use the switch firmware or the Visual Switch Manager (VSM) to install the IOS Release 12.1(1) Flash image for the ATM modules. See the "Upgrading the Module Software" section.
You must tighten the screws after inserting the module in the switch.

Hot swapping is not supported in this release. When inserting a module in or removing a module from a switch, power off the switch. If you insert or remove a module while the switch is powered on, restart the switch by using the reload command. If you upgrade the IOS Flash image on the ATM module from the switch command-line interface (CLI), restart the switch by entering the reload command.
The IOS ping and traceroute commands are not supported.
The following features are supported on the ATM modules:
The following features are supported on the ATM modules:
| Command | Description | Type | Mode |
|---|---|---|---|
atm bind | Binds a PVC to or from a VLAN. | IOS/ATM | Interface configuration |
atm pvc | Enables encapsulation type AAL5 SNAP for RFC-1483 support. | IOS/ATM | Interface configuration |
show atm vlan | Shows the relationship between the VLAN and the PVCs. | IOS/ATM | Interface configuration |
This section contains a list of known problems and suggested workarounds.
You can configure multiple MPCs on a single ATM module and bind them to the interface. Doing this might give you unreliable data. To work around this problem, configure only one MPC for each ATM module.
If a LEC is attached to VLAN 2 in static mode, it will not transmit traffic. To work around this problem, attach the LEC to any VLAN other than VLAN 2. If the LEC is attached to VLAN 1, it transmits traffic.
If you configure the bandwidth of a PVC for a value below 64 kbps, the ATM module discards frames it receives because the AAL5 reassembly timer has a duration that is too short. To work around this problem, configure PVCs for a bandwidth of 64 kbps or higher.
The ip-addr parameter does not work with the show and clear commands.
The exit and help commands do not work in interface configuration mode. To exit this mode, use the end command or Control-Z.
The ATM module does not send trap information about the link state.
The LANE clients for the ATM module might not work if the LANE servers have IOS Release 11.2(12.0.2) or later installed. To avoid this problem, make sure the LANE server is running IOS Release 11.2(12.0.2) or later. If the LANE servers are not running the required IOS release, upgrade the firmware.
If your attempt to upgrade the ATM module firmware fails while the module is in normal operation, the module continues normal operation. However, the module image stored in the Flash memory is corrupted. When you reset the ATM module, it will not find a valid IOS image, and the ATM module will not pass the power-on self-test (POST). To correct this problem, repeat the firmware upgrade procedure to download a new firmware image on the ATM module. See the Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide.
You cannot save your running configuration to a network Trivial File Transfer Protocol (TFTP) server.
New ATM module software releases can be downloaded from CCO, the Cisco Systems customer web site.
Follow these steps to download the new software and TFTP server application:
Step 2 Log into CCO. You might need to register the first time you log in.
Step 3 To locate the software files from the home page, access the FTP site at /ftp://dsbu/MPOA.
Step 4 Follow the instructions on the page to download the IOS image.
Step 5 Follow the instructions on the page to download and configure the TFTP server.
Before you can download new software to your module, you need to enter the IP address of your PC or workstation on the System Management page. If you are running the Cisco TFTP server, the PC IP address is displayed on the application title bar.
If you do not know the IP address, follow one of these steps to display it:
Follow these steps to upgrade the module software:
Switch> enable
Step 2 Enter the switch password, if applicable.
Password: <password>
Switch#
Step 3 Enter the copy command to copy the image in slot 1 or slot 2.
Switch# copy tftp://server//filename slot1:boot
Switch# copy tftp://server//filename slot2:boot
|
Note When copying the image, Cisco recommends that you overwrite the old file. This decreases potential problems when you restart the module. When the module restarts, it uses the first image it finds. |
Step 4 Restart the switch by entering the reload command:
Switch# reload
To upgrade the module software using Visual Switch Manager (VSM), do the following from the VSM System Configuration page:
|
Note To avoid errors during the upgrade process, close all other VSM pages. |
Step 2 In the Cisco ATM Upgrade Filename field, enter the name of the image file that you downloaded from CCO.
This might be a name like C29atm-m-m-121-1.bin. Do not enter the path.
Step 3 Click Upgrade ATM Module on Slot 1 or Upgrade ATM Module on Slot 2.
The upgrade can take several minutes. The TFTP server window displays a successful message when the upgrade is complete.
Step 4 Click Reboot System to restart the switch.
This section describes the procedure for upgrading your Catalyst 2900 series XL switch software by using the IOS 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 Visual Switch Manager software (VSM). To perform the steps in this section, you must have a TFTP server and a management station (such as a PC) with a CD-ROM drive. You must also access the switch management console by either of these two methods:
Follow these steps to download the new software and TFTP server application:
Step 2 Log into CCO. You might need to register the first time you log in.
Step 3 To locate the software files from the home page, go to http://www.cisco.com/cgi-bin/tablebuild.pl/cat2900XL.
Step 4 Follow the instructions on the page to download the IOS image.
Step 5 Follow the instructions on the page to download and configure the TFTP server.
Before you can download new software to your module, you need to enter the IP address of your PC or workstation on the System Management page. If you are running the Cisco TFTP server, the PC IP address is displayed on the application title bar.
If you do not know the IP address, follow one of these steps to display it:
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 2 You can access the CLI by starting a Telnet session or by connecting to the console port through 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
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-C2916M-XL switch, you need to delete the diagnostics file to make room for the new software.
|
Note If you are not upgrading this model, 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)# ^Z
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 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 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 the Enter key 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)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 17 Enter the following command to copy the new software file from the TFTP server 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 server
Step 20 Reload the new software with the following command:
switch# reload
System configuration has been modified. Save? [yes/no]:y
Proceed with reload? [confirm]
Step 21 Press Return to confirm the reload.
Your Telnet session ends when the switch resets.

Note All examples use IOS Release 11.2(8)SA5 in the upgrade procedures for the switch software. However, you can upgrade to IOS Release 11.2(8)SA6, 12.0(5)XP, or 12.0(5)XU as well. |
This section describes the procedure for upgrading switch software after you have upgraded to IOS Release 11.2(8)SA5 or above. To upgrade to IOS Release, see the "Upgrading Your Catalyst 2900 Series XL Switch Software" section. To upgrade the WS-C2916M-XL model from IOS Release 11.2(8)SA4 to IOS Release 11.2(8)SA5, you need to use the CLI procedure described in this section.
With IOS Release 11.2(8)SA5 or above, 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:
|
Note To avoid errors during the upgrade process, close any other switch VSM 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 VSM 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 VSM 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 VSM page to access the new HTML files.
