IOS - Conditional Debug

 CONDITIONAL DEBUG 


feature called "conditional debug" that sounds interesting. It seems that you can use this command to only show the output of certain protocols instead of having your screen flooded with debug information.

Understanding Steps 

OSPF and RIP have been preconfigured to generate some traffic.

Enable a debug on router Delhi which only shows RIP information on the FastEthernet0/0 interface. You are not allowed to use any access-lists.


Router Delhi ---------------------Router Lucknow 



RIP Running on Router Delhi 



RIP Running on Router Lucknow 


Lets now Proceed for Conditional Debug understanding , first let enabled debug for RIP normal 



You will notice that after enable Normal Debug you will see the RIP sending updated on every RIP enabled Interfaces like loopback and F0/0




Now the TIME to use CONDITIONAL DEBUG 


Now you notice debug will shows only RIP send on Fa0/0 interface 


Loopback information suppress and not showing in debug :)
