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 Tengigabitethernet 1/1/1, 1/2/1, 1/5/1, 1/9/1, 1/11/1, and 1/12/1.
Configure 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 configuration with various show commands.
Example of Configuring UFD
DellEMC(conf)# uplink-state-group 3

DellEMC(conf-uplink-state-group-3)# upstream tengigabitethernet 1/3-4/1
00:10:00: %STKUNIT0-M:CP %IFMGR-5-OSTATE_DN: Downstream interface set to UFD error-
disabled:
