Network Stack Debug Commands on Cisco IOS XR Software
This chapter describes the commands used to debug Network Stack problems.
debug arm api
To enable Internet Protocol Address Repository Manager (IPARM) application program interface (API) debugging, use the debug arm api command in EXEC mode. To disable IPARM API debugging, use the no form of this command.
debug arm api {all | callbacks | calls | database | db-access | errors | ipc} [job job-id | process process-id] [location node-id]
no debug arm api {all | callbacks | calls | database | db-access | errors | ipc} [job job-id | process process-id] [location node-id]

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
Debugging output is assigned high priority in the CPU process and, therefore, can affect system performance. For more information about the impact on system performance when using debug commands, refer to Using Debug Commands on Cisco IOS XR Software.
