bridge-group priority
bridge-group priority
Use the bridge-group priority configuration interface command to configure the spanning tree priority
for the bridge Ethernet and radio interfaces. Spanning Tree Protocol (STP) uses the interface priority to
select the root interface on the bridge.
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.
