Reference Guide
By default, if all the upstream interfaces in an uplink-state group go down, all the downstream interfaces in the same uplink-state group are
set into a link-down state.
In addition, in an uplink-state group, you can congure automatic recovery of downstream ports when there is a change in the link status of
uplink interfaces.
You can also bring up downstream interfaces that are in an UFD-disabled error state manually.
Congure uplink failure detection
Consider the following before conguring an uplink-state group:
• You can assign a physical port or a port channel to an uplink-state group.
• You can assign an interface to only one uplink-state group at a time.
• You can designate the uplink-state group as either an upstream or a downstream interface, but not both.
• You can congure multiple uplink-state groups and operate them concurrently.
