Sample Conguration: Uplink Failure Detection
The following example shows a sample conguration of UFD on a switch/router in which you congure as follows.
• Congure 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.
• Congure 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 conguration with various show commands.
