Usage
Information
A user-configurable number of downstream interfaces in an uplink-state group are put into a link-down
state with an UFD-Disabled error message when one upstream interface in an uplink-state group goes
down.
If all upstream interfaces in an uplink-state group go down, all downstream interfaces in the same
uplink-state group are put into a link-down state.
