When one upstream interface in an uplink-state group goes down, you can configure the number of downstream interfaces in an uplink-state group are put into a link-down state with an UFD-Disabled error message.

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.

• downstream — assigns a port or port-channel to the uplink-state group as a downstream interface.
• uplink-state-group — creates an uplink-state group and enables the tracking of upstream links.
