spanning-tree mst port-priority 51

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)#
