Introduction
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
Changes in IOS Release 12.1(4)
Note
Null packets are now added to incoming ATM cells, increasing the cell length to the Ethernet minimum of 64 bytes. This ensures they are sent out the Ethernet port. (CSCdr52760).
Cisco IOS Release 12.1(1)
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.
Installation Notes
You must tighten the screws after inserting the module in the switch.
Important Notes
Hot Swapping
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.
Unsupported IOS Commands
The IOS ping and traceroute commands are not supported.
New and Changed Information
New Features in Release 12.0(7)XF
The following features are supported on the ATM modules:
•
MPOA provides a standards-based Layer 3 switching solution for ATM networks. MPOA enables the fast routing of internetwork-layer packets across a nonbroadcast multiaccess (NBMA) network.
•
FSSRP provides an immediate backup for a LANE server and LANE broadcast-and-unknown server (BUS). You must enter the lane config fssrp command on all LANE configuration servers (LECSs) to enable FSSRP operation.
•
•
•
•
New Features in Release 12.0(5)
The following features are supported on the ATM modules:
•
Each ATM trunk supports a maximum of 64 active virtual LANs (VLANs) at one time. For IOS Release 12.0(5)XP or earlier, you must use the Enterprise Edition Software to configure multiple VLANs. If you use the standard edition software, you can only configure one VLAN.
•
The ATM module supports multiple ELANs. You can logically group users on Ethernet and ATM networks by mapping VLANs on the Ethernet network to ELANs on the ATM network.
•
The ATM modules support multiple VLAN mappings for RFC-1483 logical-link control (LLC) encapsulation for bridged Ethernet (IEEE 802.3). With RFC 1483, you can transport Ethernet frames over a maximum of 1024 permanent virtual connections (PVCs).
•
–
The following ATM modules-specific commands are supported:
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
–
For a complete list of supported IOS commands, see the Catalyst 2900 Series XL ATM Installation and Configuration Guide.
•
Caveats
This section contains a list of known problems and suggested workarounds.
Multiple MPCs
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.
Static Access Mode
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.
PVCs
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.
Commands
Show and Clear Commands
The ip-addr parameter does not work with the show and clear commands.
Exit and Help Commands
The exit and help commands do not work in interface configuration mode. To exit this mode, use the end command or Control-Z.
Link State
The ATM module does not send trap information about the link state.
Incompatible Firmware on LANE Server
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.
Upgrading the Module 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.
Running Configuration
You cannot save your running configuration to a network Trivial File Transfer Protocol (TFTP) server.
Upgrading the Module Software
New ATM module software releases can be downloaded from CCO, the Cisco Systems customer web site.

Upgrading Your Catalyst 2900 Series XL Switch Software
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:

Upgrading the Switch Software by Using VSM
Note
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:
Step 1
Note
Step 2
Step 3
Note
Step 4
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.
