How FPolicy manages external communication during node failover

If the cluster node that hosts the data ports used for FPolicy communication fails, ONTAP breaks the connection between the FPolicy server and the node.

The impact of cluster failover to the FPolicy server can be mitigated by configuring the LIF manager to migrate the data port used in FPolicy communication to another active node. After the migration is complete, a new connection is established using the new data port.

If the LIF manager is not configured to migrate the data port, the FPolicy server must wait for the failed node to come up. After the node is up, a new connection is initiated from that node with a new Session ID.
