Status After Failure
When a node in the cluster fails, the connections hosted by that node are seamlessly transferred to other nodes; state information for traffic flows is shared over the control node's cluster control link.
If the control node fails, then another member of the cluster with the highest priority (lowest number) becomes the control node.
The Firewall Threat Defense automatically tries to rejoin the cluster, depending on the failure event.

When the Firewall Threat Defense becomes inactive and fails to automatically rejoin the cluster, all data interfaces are shut down; only the Management interface can send and receive traffic. |
