7.3.9 show uplink-state-group
This command is used to validate the UFD status on leaf switches in this topology. Status: Enabled, Up
indicates UFD is enabled and no interfaces are currently disabled by UFD.
S4048-Leaf1#show uplink-state-group
Uplink State Group: 1 Status: Enabled, Up
If an interface happens to be disabled by UFD, the show uplink-state-group command output will
appear as follows:
Uplink State Group: 1 Status: Enabled, Down
Note: When an interface has been disabled by UFD, the show interfaces interface command for
affected interfaces indicates it is error-disabled as follows:
S4048-Leaf-1#show interfaces te 1/4
TenGigabitEthernet 1/4 is up, line protocol is down(error-disabled[UFD])
-- Output truncated –-
7.3.10 show spanning-tree rstp brief
This command validates spanning tree is enabled on the leaf switches. All interfaces are forwarding (Sts
column shows FWD). One of the leaf switches (S4048-Leaf1 in this example) is the root bridge and sever-
facing interfaces (Po 1 in this example) are edge ports.
