Use the no spanning-tree mst cost command to specify auto-configuration mode.
Path cost takes precedence over interface priority.
Example
Console(config)#interface ethernet ethernet 1/5
Console(config-if)#spanning-tree mst 1 cost 50
Console(config-if)#
Related Commands
spanning-tree mst port-priority
Use the spanning-tree pathcost method command on page 4-206 to set the path cost method.
spanning-tree mst port-priority
This command configures the interface priority on a spanning instance in the Multiple Spanning Tree. Use the no form to restore
the default.
Syntax
spanning-tree mst instance_id port-priority priority no spanning-tree mst instance_id port-priority
instance_id - Instance identifier of the spanning tree.
(Range: 0-4094, no leading zeroes)
priority -Priority for an interface. (Range: 0-240 in steps of 16)
Default Setting
128
Command Mode
Interface Configuration (Ethernet, Port Channel)
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.
Where more than one interface is assigned the highest priority, the interface with lowest numeric identifier will be enabled.
Example
Console(config)#interface ethernet ethernet 1/5
Console(config-if)#spanning-tree mst 1 port-priority 0
Console(config-if)#
