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 1/1, 1/2, 1/5, 1/9, 1/11, and 1/12.
● Configure 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 configuration with various show commands.
Example of Configuring UFD
DellEMC(conf)# uplink-state-group 3
00:08:11: %STKUNIT0-M:CP %IFMGR-5-ASTATE_UP: Changed uplink state group Admin state to
up:
Group 3
DellEMC(conf-uplink-state-group-3)# downstream gigabitethernet 1/1-2,5,9,11-12
DellEMC(conf-uplink-state-group-3)# downstream disable links 2
DellEMC(conf-uplink-state-group-3)# upstream gigabitethernet 1/3-4
00:10:00: %STKUNIT0-M:CP %IFMGR-5-OSTATE_DN: Downstream interface set to UFD error-
disabled:
Gi 1/1
