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
Upstream Interfaces:ethernet1/1/49(down) ethernet1/1/50(down)
Downstream Interfaces:port-channel1(disabled) port-channel101(disabled) port-
channel102(disabled) port-channel3(disabled) port-channel5(disabled)
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-Leaf1# show interface port-channel 1
Port-channel 1 is up, line protocol is down(error-disabled[UFD])
--- Output is truncated ---
8.1.8
Show spanning-tree brief
This command validates STP 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 1,3,5,101,102 in this example) are edge ports.
