If on Active Passive PA  both shows running config not sync 

 

Say  failover happens for somereason  or we trigger the manual failover  bgy suspending the active PA will then

 

Passive PA becomes active and start passing the traffic even though running config is not syc between two?

@MP18,

The passive PA will still become active, and will still pass traffic, it simply will not be utilizing the same configuration file. This can cause issues for example if you've since added/removed additional security policies that are not present on the peer HA unit; a function that is expected to be working could possibly stop functioning simply because the configuration was not in sync with your peer unit.

@BPry 
I m having similar issue and I am interested to know how to safely make the configurations same on both the HA pairs?

Thanks

@paragkarki143,

What error are you seeing recorded in the logs for a configuration sync failure? What happens if you attempt to sync the configuration from the active to the passive manually? You ultimately need to figure out why the configuration isn't syncing automatically. That could be something as simple as a user holding a configuration lock on the passive unit, or a larger issue.
