Sample Configuration: Uplink Failure Detection
The following example shows a sample configuration of UFD on a switch/router in which you configure as follows.
● Configure uplink-state group 3.
● Add downstream links Tengigabitethernet 1/1/1, 1/2/1, 1/5/1, 1/9/1, 1/11/1, and 1/12/1.
● Configure two downstream links to be disabled if an upstream link fails.
● Add upstream links Tengigabitethernet 1/3/1 and 1/4/1.
● Add a text description for the group.
● Verify the configuration with various show commands.
