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.
Group
Use the Link Dependency Group Status page to configure link dependency groups.
Link dependency allows the link status of one interface to be dependent on the link
status of another interface. Link state groups define the interface link dependency.
