Usage
Information
After you enter the command, to assign upstream and downstream interfaces to
the group, enter Uplink-State-Group Configuration mode.
An uplink-state group is considered to be operationally up if at least one upstream
interface in the group is in the Link-Up state.
An uplink-state group is considered to be operationally down if no upstream
interfaces in the group are in the Link-Up state. No uplink-state tracking is
performed when a group is disabled or in an operationally down state.
To disable upstream-link tracking without deleting the uplink-state group, use the
no enable command in uplink-state-group configuration mode.
