Parameter
value: Bridge priority, in the range 0 to 65,535. The default value is 32,768.
Description
Use the bridge stp priority command to assign a priority to the bridge.
Use the undo bridge stp priority command to restore the default priority of the bridge.
The ID of a bridge consists of two parts: bridge priority and bridge MAC address. During
a spanning tree calculation in a network, the bridge with the lowest ID is elected as the
root. The process is as follows:
z Compare the priorities of the bridges in the network. The one with the lowest
bridge priority is elected as the root.
z In case multiple bridges in the network have the same priority, compare their MAC
addresses and elect the bridge with the lowest MAC address as the root.
When STP is enabled, changing the priority of a bridge may cause spanning tree
recalculation.
Example
# Set the bridge priority to 500.
[Router] bridge stp priority 500
