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 frames 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
AsGOS# configure terminal
AsGOS(config)# interface eth0
AsGOS(config-if)# bridge-group 4 instance 3 priority 121
