What is cufwFOLink?
This read-only InterfaceIndex identifies, via IF-MIB numbering, which interface the two HA units use for general failover communication. An admin uses it to know exactly which physical link carries the failover control traffic, which is critical when troubleshooting a suspected failover-link outage. Checking this interface's own IF-MIB statistics would tell an admin whether the failover link itself is experiencing errors that could be interfering with HA coordination.
