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