Configure Link Dependency
The link dependency feature provides the ability to enable or disable one or more ports based
on the link state of one or more different ports. With link dependency enabled on a port, the
link state of that port is dependent on the link state of another port. For example, if port A is
dependent on port B and the switch detects a link loss on port B, the switch automatically
brings down the link on port A. When the link is restored to port B, the switch automatically
restores the link to port A.
