bridge priority
bridge priority
Use the bridge priority global configuration command to configure the spanning tree priority for the
bridge. STP uses the bridge priority to select the spanning tree root. The lower the priority, the more
likely it is that the bridge will become the spanning tree root.
The radio and Ethernet interfaces and the native VLAN on the bridge are assigned to bridge group 1 by
default. When you enable STP and assign a priority on bridge group 1, STP is enabled on the radio and
Ethernet interfaces and on the primary VLAN, and those interfaces adopt the priority assigned to bridge
group 1. You can create bridge groups for sub-interfaces and assign different STP settings to those bridge
groups.
