SSIDs and VLAN on access points

Unanswered Question
May 17th, 2007

The commands to map an SSID to a VLAN on an IOS access point are basically like this:

[snip]

dot11 ssid MYSSID

vlan 5

!

interface Dot11Radio0

ssid MYSSID

!

interface Dot11Radio0.5

encapsulation dot1q 5

bridge-group 5

!

interface FastEthernet0

!

interface FastEthernet0.5

encapsulation dot1q 5

bridge-group 5

!

[snip]

My question is this: what does the command "vlan 5" actually do? Does it map MYSSID to bridge-group 5, which is then mapped to 802.1q tag 5 by the subinterface configurations (so that the tag number is arbitrary), or does it map MYSSID to 802.1q tag 5 on the radio interface, which is then bridged to the appropriate dot1q subinterface on the wired side by the bridge group (so that the bridge group number is arbitrary)?

I have this problem too.

Vlan tag is tied to SSID and Bridge group is also tagged to appropriate vlan mentioned as bridge group number
