Hardware Requirements
The ATM modules work with modular Catalyst 2900 XL switches that use firmware version 11.2(8)SA5 or later. You can check the installed firmware version by using the show version privileged EXEC command on the switch. For firmware upgrade procedures, refer to the switch software configuration guide. You can access this document on Cisco.com.
Note
Upgrading the Module Software
You can download new ATM module software releases from Cisco.com.
Downloading Files from Cisco.com
Follow these steps to download the new software and, if necessary, the Trivial File Transfer Protocol (TFTP) server application from Cisco.com to your management station:

Step 4
The readme.txt file describes how to download the TFTP server application. New features provided by the software are not available until you reload the software.
Displaying the IP Address of 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 using 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:

Upgrading the Module Software by Using the CLI
Follow these steps to upgrade the module software:
Step 1
Switch> enableStep 2
Password: <password> Switch#Step 3
Switch# copy tftp://server//filename slot1:bootSwitch# copy tftp://server//filename slot2:boot
Note
Step 4
Switch# reload
Upgrading the Module Software by Using VSM
To upgrade the module software by using Visual Switch Manager (VSM), follow these steps on the VSM System Configuration page:
Note
Step 1
Step 2
This might be a name like C29atm-m-m-121-1.bin. Do not enter the path.
Step 3
The upgrade can take several minutes. The TFTP server window displays a message when the upgrade is complete.
Step 4
Installation Notes
You must tighten the screws after inserting the module in the switch.
Documentation Notes
The Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide states the incorrect encapsulation type in Step 4, Chapter 3, "Configuration Example for an RFC-1483 PVC." This is the corrected text for Step 4.
Step 4 Create PVCs for RFC 1483 by entering the atm pvc command:
atm(config-if)#atm pvc 100 0 100 aal5snap 20000 20000 32
atm(config-if)#atm pvc 101 0 101 aal5snap
atm(config-if)#atm pvc 200 0 200 aal5snapThe online document contains the corrected procedure.
Limitations and Restrictions
You should review this section before you begin working with the switches and ATM modules. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

Important Notes
This section provides information related to these releases:
Release 12.1(16)
Note
Release 12.1(4)
Note
Release 12.0(7)XF
These 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 a LANE broadcast-and-unknown server (BUS). You must enter the lane config fssrp command on all LANE configuration servers (LECSs) to enable FSSRP operation.
•
•
•
•
Release 12.0(5)
These features are supported on the ATM modules:
•
Each ATM trunk supports a maximum of 64 active virtual 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 PVCs.
Unresolved Caveats
These are unresolved caveats in Release 12.1(16):
•
Under heavy traffic load, the ATM module might freeze and restart itself.
There is no workaround for this.
•
The show atm interface atm privileged EXEC command periodically displays incorrect output for an ATM module configured for LAN emulation (LANE). Specifically, incorrect values can appear for the transmit load (txload) and the 5-minute output rate counters. This condition corrects itself after an undetermined amount of time. The erroneous information does not affect the operation of the ATM module and switch.
There is no workaround.
Resolved Caveats
These caveats are resolved in Release 12.1(16):
•
The ATM module now continues to send data in permanent virtual connections (PVCs).
•
The ATM module no longer stop operating after you remove a PVC statement from the configuration file.
•
The Operation, Administration, and Maintenance (OAM) feature now detects connectivity between two PVCs over an ATM cloud after connectivity is lost and then re-established.
