Understanding Link-State Tracking
Link-state tracking, also known as trunk failover, binds the link state of multiple interfaces. Link-state tracking
can be with server NIC adapter teaming to provide redundancy in the network. When the server NIC adapters
are configured in a primary or secondary relationship, and the link is lost on the primary interface, network
connectivity is transparently changed to the secondary interface.
An interface can be an aggregation of ports (an EtherChannel) or a single physical port in either access
or trunk mode.
