7.24 spanning-tree instance priority
Use this command to set the port priority for a bridge group. Use the no parameter with this command
to restore the default priority value.
Command Syntax
spanning-tree instance instance-id port-priority priority
no spanning-tree instance instance-id port-priority
instance-id Specify
the
identifier.
priority
Specify the port priority (a lower priority indicates greater likelihood of the
interface becoming a root). The range is 0 to 240.
Command Mode
Interface mode
Default
The default value of port priority for each instance is 128.
Usage
The Multiple Spanning Tree Protocol uses port priority as a tiebreaker to determine which port should
forward frame for a particular instance on a LAN, or which port should be the root port for an instance.
A lower value implies a better priority. In the case of the same priority, the interface index will serve as
the tiebreaker, with the lower-numbered interface being preferred over others.
The permitted range is 0-240. The priority values can only be set in increments of 16.
Examples
Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# spanning-tree 3 priority 112
