The radio and Ethernet interfaces and the native VLAN on the access point 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.

Configuring STP Settings

Beginning in privileged EXEC mode, follow these steps to configure STP on the
access point:
1. Enter global configuration mode.
configure terminal
2. Enter interface configuration mode for radio or Ethernet interfaces or sub-
interfaces.
• The 2.4 GHz radio and the 2.4 GHz 802.11n radio is 0.
• The 5 GHz radio and the 5 GHz 802.11n radio is 1.
The fast Ethernet interface is 0.
interface { dot11radio number | fastethernet number }
3. Assign the interface to a bridge group. You can number your bridge groups
from 1...255.
bridge-group number
4. Counteract the command that automatically disables STP for a bridge
group. STP is enabled on the interface when you enter the bridge n
protocol ieee command.
