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 Gigabitethernet 0/1, 0/2, 0/5, 0/9, 0/11, and 0/12.
• Configure two downstream links to be disabled if an upstream link fails.
• Add upstream links Gigabitethernet 0/3 and 0/4.
• Add a text description for the group.
• Verify the configuration with various show commands.
