EIGRP Debug Commands on Cisco IOS XR Software

---

This chapter describes the commands used to debug the Enhanced Interior Gateway Routing Protocol (EIGRP) on Cisco IOS XR software.

debug eigrp fsm

To display debugging information about the Enhanced Interior Gateway Routing Protocol (EIGRP) dual finite state machine (fsm) events and actions, use the debug eigrp fsm command in EXEC mode. To disable debugging output, use the no form of this command.

debug eigrp fsm

no debug eigrp fsm

Syntax Description

This command has no arguments or keywords.

Defaults

Debugging is disabled.

Command Modes

EXEC

Command History

Release	Modification
Release 3.3.0	This command was introduced on the Cisco CRS-1 and Cisco XR 12000 Series Router.
Release 3.4.0	No modification.
Release 3.5.0	No modification.

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.
