High Availability - HA2 Session Synchronization
Session information will be synchronized with the passive device. This is necessary between the HA pair devices because if there is a failover event and traffic starts to flow from primary unit to secondary unit which is active after a failover it should have the session in the data plane so that the packets should match the synced session and quickly get processed and forwarded and not create the session again which will introduce latency and connection drops.
