To display VLAN information, including the STP state of each VLAN, enter the following command at any CLI
level:
BigIron(config)# show vlan
Syntax: show vlan [<vlan-id> | ethernet <portnum>]
BigIron(config)# show vlan

This example shows information for port-based VLANs 1 and 2. VLAN 1 is the default VLAN and VLAN 2 is a
user-configured VLAN. The display also shows information for the SINGLE-SPANNING-TREE-VLAN (4094).
Notice that for port-based VLAN 1, a message indicates that the VLAN is in the single STP domain. For VLAN 2,
a message indicates the VLAN is not a member of the single STP domain. When single STP was enabled,
(multiple-instance) STP was already enabled on VLAN 1 but was disabled on VLAN 2. The VLANs still provide
separate Layer 2 broadcast domains. Only the STP domain is shared across all the ports.
Also notice that the SINGLE-SPANNING-TREE-VLAN contains all the ports in the device except those in VLAN 2,
because STP is disabled on those ports.
