8.2.4 Show VLT detail
This command is used to validate VLT LAG status on leaf switches in this topology. This command shows the
status and active VLANs of all VLT LAGs. The local and peer status must both be up.
S4048-Leaf3#show vlt detail
Local LAG Id Peer LAG Id Local Status Peer Status Active VLANs
------------ ----------- ------------ ----------- -------------
1 1 UP UP 200
3 3 UP UP 200
5 5 UP UP 200
101 101 UP UP 200
102 102 UP UP 200
8.2.5 Show VLT mismatch
This command highlights configuration issues between VLT peers. Mismatch examples include incompatible
VLT configuration settings, VLAN differences, the different switch operating system versions and STP
inconsistencies. There should be no output to this command on any switch correctly configured for VLT. If
there is, resolve the mismatch.
S4048-Leaf3#show vlt mismatch
S4048-Leaf3#
8.2.6 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-Leaf3#show uplink-state-group 1
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
When an interface or prort-channel has been disabled by UFD, the show port-channel value command
for affected interfaces indicates it is error-disabled as follows:
S4048-Leaf3#show interface port-channel 1
Port-channel 1 is up, line protocol is down(error-disabled[UFD])
-- Output truncated –-
8.2.7 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 are edge ports.
