Explanation

Heartbeat polling is a core HA function to monitor connectivity between HA peers, leveraging ICMP pings to determine link health and availability. Heartbeat Polling uses ICMP pings to verify the connectivity and health of the HA peers. If heartbeat polling fails, the firewall considers the peer to be down and may initiate failover. If ICMP pings fail, checking heartbeat polling logs helps identify if link or path monitoring triggers
