Q:

What are all the debugging and troubleshooting commands that we use to debug VRRP flapping?



A:

The general basic troubleshooting steps are,

  • Find out whether the FLAPS are happening because of issues with the network or the Mobility Controller?
  • Check if any port errors or port flaps?
  • Any changes in the network topology related to STP?
  • Identify if there is a similar VRRP id exist in the same broadcast network?

Some useful commands,

  show vrrp stats all

  show log all
 
Enabling logging,
 
config t

logging level debugging system process fpapps

logging level debugging network process fpapps

end

 

Enabling packet capture

External packet capture  on external Ethernet interfaces is useful to determine if VRRP packets are seen in the wired.

To enable the packet capture on the controller,

packet-capture controlpath sysmsg 68

 

To disable the controller packet capture,

packet-capture controlpath sysmsg disable

 

To view the controller packet capture setting,

show packet-capture
