HA Heartbeat Polling and Hello Messages

The HA peers use hello messages and heartbeats to verify that the peer is responsive and operational. Hello messages are sent from one peer to the other at the configured Hello Interval to verify the state of the other. The heartbeat is an ICMP ping to the HA peer, and the peer responds to the ping to establish that the peers are connected and responsive. By default, the interval is 1,000 milliseconds for the heartbeat and 8,000ms for hello messages.
