MPLS Traffic Engineering Debug Commands on Cisco IOS XR Software

This chapter describes the commands used to debug Multiprotocol Label Switching Traffic Engineering (MPLS-TE) on Cisco IOS XR software.

debug mpls te-igp

To display information about the MPLS-TE IGP library, use the debug mpls te-igp command in EXEC mode. To disable debugging output, use the no form of this command.

This command has no arguments or keywords.

Defaults

No default behavior or values

Command Modes

EXEC

Modification

Release 3.2

This command was supported on the Cisco CRS-1 and
Cisco XR 12000 Series Router.

Release 3.3.0

No modification.

Release 3.4.0

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.
