Switch#
29-5 spanning-tree mst
This command is used to configure the path cost and portpriority parameters for any MST instance
(including the CIST with instance ID 0). Use the no form of this command to revert to the default
setting.
spanning-tree mst INSTANCE-ID {cost COST | port-priority PRIORITY}
no spanning-tree mst INSTANCE-ID {cost | port-priority}
Parameters
INSTANCE-ID
Specifies the MSTP instance identifier.
cost COST
Specifies the path cost for an instance.This value must be between 1
and 200000000.
port-priority PRIORITY
Specifies the port priority for an instance. This value must be between
0 and 240 in increments of 16.
Default
The cost value depends on the port speed. The faster the interface's speed is will indicate a smaller
cost. MST always uses long path costs.
The default priority value is 128.
Command Mode
Interface Configuration Mode.
