How Uplink Failure Detection Works
UFD creates an association between upstream and downstream interfaces. The association of uplink and
downlink interfaces is called an uplink-state group. An interface in an uplink-state group can be a physical
interface or a port-channel (LAG) aggregation of physical interfaces.
An enabled uplink-state group tracks the state of all assigned upstream interfaces. Failure on an upstream
interface results in the automatic disabling of downstream interfaces in the uplink-state group. As a result,
downstream devices can execute the protection or recovery procedures they have in place to establish
alternate connectivity paths as shown in
