View to which instance a VLAN is mapped using the command show spanning-tree mst vlan from EXEC Privilege mode, as shown in the example in Interoperate with Non-FTOS Bridges. View the forwarding/discarding state of the ports participating in an MSTI using the command show spanning-tree msti from EXEC Privilege mode, as shown in the following example.
