2.9 Tracking Uplink Failures

The Uplink Failure Tracking Feature (ULFT) is useful for Supermicro switches. This helps servers move to
redundant Ethernet ports in case any switch uplink fails.
The user can configure one or more groups for ULFT. Each group can have one or more uplinks and one or
more downstream ports.
Step Command
Step 1
configure terminal
Step 2
link-status-tracking enable
Step 3
link-status-tracking group <id>
Step 4
link-status-tracking group <id> upstream
Step 5
link-status-tracking group <id> downstream
Step 6
link-status-tracking disable
Step 7
End
Step 8
show link-status-tracking
write startup-config
Step 9
For example, if it is desired to bring down all fourteen ports from fx 0/1 to fx 0/14 when uplink interfaces fx
0/15 and fx 0/16 go down:
SMIS# configure terminal
SMIS(config)# link-status-tracking enable
SMIS(config)# link-status-tracking group 1
SMIS(config)# interface range fx0/15-16
SMIS(config-if)# link-status-tracking group 1 upstream
SMIS(config-if)# exit
SMIS(config)# interface range fx0/1-14
SMIS(config-if)# link-status-tracking group 1 downstream
SMIS(config-if)# exit
SMIS(config)# link-status-tracking disable
SMIS(config)# show link-status-tracking
Note:
If more than one uplink port is configured, all downstream ports will be brought down only when all
upstream ports are down.
