Spanning-Tree Commands 271
spanning-tree mst cost
The spanning-tree mst cost Interface Configuration mode command configures 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 configuration,
use the
no form of this command.
Syntax
spanning-tree mst instance-id cost cost
no spanning-tree mst instance-id cost
• instance-ID — ID of the spanning -tree instance (Range: 1-15).
