ATM SVC Troubleshooting Enhancements
Feature History
This document describes the ATM SVC Troubleshooting Enhancements feature in Cisco IOS Release 12.2(8)T. It includes the following sections:
•
Supported Standards, MIBs, and RFCs
•
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 nbma and debug atm native commands are used to debug problems with Resource Reservation Protocol (RSVP) SVC creation and teardown. The debug atm native command can also be used to debug problems with SVCs created using static maps.
Benefits
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.
Restrictions
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.
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:

MIBs
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 Cisco.com at the following URL:

RFCs
No new or modified RFCs are supported by this feature.
Prerequisites
The tasks in this document assume that ATM SVCs or RSVP SVCs are already created.
Configuration Tasks
None.
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
None.
Command Reference
This section documents new commands. All other commands used with this feature are documented in the Cisco IOS Release 12.2 command reference publications.
debug atm native
To display ATM switched virtual circuit (SVC) signaling events, use the debug atm native command in privileged EXEC configuration mode. To disable the debugging output, use the no form of this command.
debug atm native {[api] | [conn] | [error] | [filter]}
no debug atm native
Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Native ATM API is the layer above the signaling API. Static map and Resource Reservation Protocol (RSVP) clients use the native ATM API to interact with the signaling API to create ATM SVCs.
Use the debug atm native command to diagnose problems in the creation of static map and RSVP ATM SVCs.
Examples
The following example shows sample output for the debug atm native command with the api keyword:
Router# debug atm native api0:24:59:NATIVE ATM :associate endpoint00:24:59:NATIVE ATM :ID (3) prep outgoing call, conn_type 000:24:59:NATIVE ATM :ID (3) set connection attribute for 500:24:59:NATIVE ATM :ID (3) query connection attribute 800:24:59:NATIVE ATM :ID (3) set connection attribute for 800:24:59:NATIVE ATM :ID (3) set connection attribute for 900:24:59:NATIVE ATM :ID (3) set connection attribute for 1000:24:59:NATIVE ATM :ID (3) set connection attribute for 700:24:59:NATIVE ATM :ID (3) set connection attribute for 600:24:59:NATIVE ATM :ID (3) set connection attribute for 200:24:59:NATIVE ATM :ID (3) set connection attribute for 000:24:59:NATIVE ATM :ID (3) query connection attribute 1200:24:59:NATIVE ATM :ID (3) set connection attribute for 1200:24:59:NATIVE ATM :ID (3) query connection attribute 1300:24:59:NATIVE ATM :ID (3) set connection attribute for 1300:24:59:NATIVE ATM :ID (3) connect outgoing call00:24:59:NATIVE ATM :ID (3) callback, CONNECT receiveddebug atm nbma
To display setup and teardown events for ATM switched virtual circuits (SVCs) configured using the Resource Reservation Protocol (RSVP), use the debug atm nbma command in privileged EXEC mode. To disable the debugging output, use the no form of this command.
debug atm nbma [api]
no debug atm nbma
Syntax Description
api
(Optional) Nonbroadcast multiaccess (NBMA) ATM application program interface (API). Displays events that occur as a result of the exchange between RSVP and the NBMA API.
Defaults
No default behavior or values.
Command Modes
Privileged EXEC
Command History
Usage Guidelines
Use the debug atm nbma command to diagnose problems in the creation of RSVP SVCs.
The RSVP application creates SVCs by using the NBMA API. The debug atm nbma command with the api keyword displays events that occur as a result of the exchange between RSVP and the NBMA API.
Examples
The following example shows sample output for the debug atm nbma command:
Router# debug atm nbma api00:52:50:NBMA-ATM-API - atm_setup_req00:52:50:NBMA_ATM-API - nbma_atm_fill_blli00:52:50:NBMA_ATM-API - nbma_atm_fill_bhli00:52:50:NBMA_ATM-API - nbma_atm_callbackMsg - NATIVE_ATM_OUTGOING_CALL_ACTIVE00:52:50:NBMA_ATM-API - rcv_outgoing_call_active00:52:50:NBMA_ATM-API - nbma_svc_lookup
