SPANNING TREE MST INSTANCE PRIORITY

spanning-tree mst instance priority

Overview Use this command in Interface Configuration mode for a switch port interface only
to set the port priority for an MST instance (MSTI).
Use the no variant of this command to restore the default priority value (128).
Syntax
spanning-tree mst instance <instance-id> priority <priority>
no spanning-tree mst instance <instance-id> [priority]
Default The default is 128.
Mode Interface Configuration mode for a switch port interface.
Usage This command sets the value of the priority field contained in the port identifier.
The MST algorithm uses the port priority when determining the root port for the
switch in the MSTI. The port with the lowest value is considered to have the highest
priority and will be chosen as root port over a port - equivalent in all other aspects
- but with a higher priority value.
