HSRP Debug Commands on Cisco IOS XR Software

---

This chapter describes the commands used to debug Hot Standby Router Protocol (HSRP) problems.

debug hsrp all

To enable the debugging of all Hot Standby Router Protocol (HSRP) server activity including HSRP errors, events, and packets, use the debug hsrp all command in EXEC mode. To disable the debugging of all HSRP server activity, use the no form of this command.

debug hsrp all [interface-type interface-instance] [group group-id]

no debug hsrp all [interface-type interface-instance] [group group-id]

Syntax Description

interface-type	(Optional) Interface type. For more information, use the question mark (?) online help function.
interface-instance	(Optional) Either a physical interface instance or a virtual interface instance as follows: •Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation. –rack: Chassis number of the rack. –slot: Physical slot number of the modular services card or line card. –module: Module number. A physical layer interface module (PLIM) is always 0. –port: Physical port number of the interface. Note In references to a Management Ethernet interface located on a route processor card, the physical slot number is alphanumeric (RP0 or RP1) and the module is CPU0. Example: interface MgmtEth0/RP1/CPU0/0. •Virtual interface instance. Number range varies depending on interface type. For more information about the syntax for the router, use the question mark (?) online help function.
group group-id	(Optional) Restricts debug messages to a particular group. Range is 0 to 255.

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.
