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

00:10:00: %STKUNIT0-M:CP %IFMGR-5-OSTATE_DN: Downstream interface set to UFD error-disabled:
