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
Description
Step 1
configure terminal
Enters the configuration mode
Step 2
link-status-tracking enable
Enabling uplink failure tracking feature
Step 3
link-status-tracking group <id>
Creating group
Step 4
link-status-tracking group <id> upstream
Adding uplink to group
Step 5
link-status-tracking group <id> downstream
Adding downstream ports to group
Step 6
link-status-tracking disable
Disabling uplink failure tracking feature
Step 7
End
Exits the configuration mode.
Step 8
show link-status-tracking
Displays the link-status-tracking
configuration.
Step 9
write startup-config
Optional step – saves this configuration
to be part of startup configuration.
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.
