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 twentyFiveGigE 1/1, 1/2, 1/5, 1/9, 1/11, and 1/12.
● Configure two downstream links to be disabled if an upstream link fails.
● Add upstream links twentyFiveGigE 1/3 and 1/4.
● Add a text description for the group.
● Verify the configuration with various show commands.
