Dot11 Sub-Interfaces and Gigabit Sub Interfaces.

I'm trying to configure this 1252 AP (Autonomous), and I have a question in regards to Dot 11 Radio sub interfaces and Fast Ethernet sub interfaces.

I was looking through the Cisco Configuration Guide for the AP1252 and saw this:

interface dot11radio 0

ssid NAME

vlan 01

end

conf t

interface fa0.1

encapsulation dot1q 2

bridge-group 2

interface dot11radio0.2

encapsulation dot1q 2

bridge-group 2

My question is, is the number "2" after the encapsulation commands under the sub interfaces what binds them to vlan 02? Is this right? Sort of how the bridge-group 2 binds them to bridge-group 2?

What is the purpose of the sub interfaces?

Is it correct to assume that if I want to bridge wireless clients to my wired network I would have to have a configuration like this:

SSID maps to VLAN 10

Radio and Ethernet Subinterfaces map to VLAN 10 also and get bridged under bridge-group 10. Therefore, any client associated to VLAN 10 would be a part of bridge-group that bridges the gigabit and radio sub-interfaces?

Sorry if I'm answering my own questions. I just want to understand this completely.

"encapsulation dot1q 2" means dot1q encapsulation enabled on VLAN 2.

"encapsulation dot1q 111" means dot1q encapsulation enabled on VLAN 111
