What is cufwFOStateLink?

This read-only InterfaceIndex identifies, via IF-MIB numbering, which interface the HA units use specifically to pass connection state information between them, which may be the same or a different interface than cufwFOLink. An admin uses it to isolate the link responsible for stateful failover replication when diagnosing why session state isn't syncing properly. High utilization or errors on this specific interface would explain incomplete stateful failover even if the general failover link looks healthy.

Examples
