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 0/1, 0/2, 0/5, 0/9, 0/11, and 0/12.
● Configure 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 configuration with various show commands.
Example of Configuring UFD (S50)
Dell(conf)# uplink-state-group 3
00:08:11: %STKUNIT0-M:CP %IFMGR-5-ASTATE_UP: Changed uplink state group Admin state to
up:

Dell(conf-uplink-state-group-3)# downstream tengigabitethernet 0/1-2,5,9,11-12
Dell(conf-uplink-state-group-3)# downstream disable links 2
Dell(conf-uplink-state-group-3)# upstream tengigabitethernet 0/3-4
00:10:00: %STKUNIT0-M:CP %IFMGR-5-OSTATE_DN: Downstream interface set to UFD error-
disabled:
Te 0/1
Dell#
00:10:00: %STKUNIT0-M:CP %IFMGR-5-OSTATE_DN: Changed interface state to down: Te 0/1
