• Use the no spanning-tree mst cost command to specify
auto-configuration mode.
• Path cost takes precedence over interface priority.

• instance_id - Instance identifier of the spanning tree.
(Range: 0-4094, no leading zeroes)

Command Usage
This command defines the priority for the use of an interface in the
multiple spanning-tree. If the path cost for all interfaces on a switch are
the same, the interface with the highest priority (that is, lowest value)
will be configured as an active link in the spanning tree.
