same VLAN mapping, the same configuration revision number and the same
name.
Example

spanning-tree mst cost
Use the spanning-tree mst cost command in Interface Configuration mode
to configure the path cost for multiple spanning tree (MST) calculations. If a
loop occurs, the spanning tree considers path cost when selecting an interface
to put in the forwarding state. To return to the default port path cost, use the
no form of this command.
