Cisco Cisco IOS Software Release 12.2(27)SBC

To view debug output that displays the operation of unicast reverse path forwarding (URPF) MIB objects 
and the helper software, use the debug ip verify mib command in privileged EXEC mode. To disable 
debugging for URPF, use the no form of this command. 

no debug ip verify mib

This command has no arguments or keywords.

Privileged EXEC 

Debug information for the URPF MIB is collected only when logging is enabled. URPF messages are 
stored in the logging buffer, and they are not displayed on the console unless you use the debug ip verify 
mib command. 

The following example shows sample output of the debug ip verify mib command:

router# debug ip verify mib
