ATM SVC Troubleshooting Enhancements

ATM SVC Troubleshooting Enhancements

Last Updated: December 4, 2012

Feature History




This feature was introduced.

This document describes the ATM SVC Troubleshooting Enhancements feature in Cisco IOS Release 12.2(8)T. It includes the following sections:

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to An account on is not required.

Feature Overview

The ATM SVC Troubleshooting Enhancements feature introduces two new debug commands: debug atm native and debug atm nmba. These commands can be used to troubleshoot ATM switched virtual circuits (SVCs). The debug atm nbmaand debug atm native commands are used to debug problems with Resource Reservation Protocol (RSVP) SVC creation and teardown. The debug atm nativecommand can also be used to debug problems with SVCs created using static maps.


The ATM SVC Troubleshooting Enhancements feature provides two debug commands that can be used to troubleshoot ATM SVCs that were created using static maps or RSVP.


The debug atm nmba command can be used only to debug RSVP SVCs. The debug atm native command can be used only to debug problems with RSVP SVCs or SVCs that were created using static maps.

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on If you have forgotten or lost your account information, send a blank e-mail to An automatic check will verify that your e-mail address is registered with If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on by following the directions at .

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Supported Standards and MIBs and and RFCs


API Semantics for Native ATM Services , ATM Forum, February 1999


No new or modified MIBs are supported by this feature.

To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on at the following URL:

The tasks in this document assume that ATM SVCs or RSVP SVCs are already created.

Configuration Tasks


Monitoring and Maintaining ATM SVCs

To monitor and maintain RSVP SVCs or ATM SVCs that were created using static maps, use the following commands in privileged EXEC mode:



Router# debug atm native {[api] | [conn] | [error] | [filter]} 

Displays Native ATM API events.

Router# debug atm nbma [api]

Displays NBMA API events during the creation of RSVP SVCs.

Configuration Examples
