VLAN Over Remote Bridges (1240AG)

[EE_36220]

Hi,

I've an AP connecting to the backbone switch via 2 wireless bridge links as shown below. Currently, it is operating as flat lan.

Would like to know if it can be coverted to vlan mode so that I can support wireless clients of different vlans at the remote end?

Switch ----------- 1240AG--------------------/-----------------1240AG--------------------/------------------------1240AG

            Eth              Root         802.11b/g        Non       Root             802.11a                Non      AP        802.11b/g  Clients

            Trunk           Bridge                             Root      Bridge                                      Root                 SSID1 -- vlan 10

            vlan 1                                                 Bridge                                                   Bridge              SSID2 -- vlan 20

            vlan 10                                                                                                                                   SSID3 -- vlan 30    

            vlan 20

            vlan 30

Thanks!

Eric,

     Yes it can.  On the bridges you'll want to define the sub-interfaces for the VLAN that you want to pass.  You only need the one SSID on the bridge to accomplish this, as it is the 'connection' between the bridges.

So basiclly you need

int dot11radio 0.10 ( or 1 if you are using the 5GHz to bridge)

encapsulation dot1q 10

bridge-group 10

!

int dot11radio 0.20

encapsulation dot1q 20

bridge-group 20

!

int dot11radio 0.30

encapsulation dot1q 30

bridge-group 30

!

int f0.10

encapsulation dot1q 10

bridge-group 10

!

int f0.20

encapsulation dot1q 20

bridge-group 20

!

int f0.30

encapsulation dot1q 30

bridge-group 30 int dot11radio 0.10
encapsulation dot1q 10
bridge-group 10
!
int dot11radio 0.20
encapsulation dot1q 20
bridge-group 20
!
int dot11radio 0.30
encapsulation dot1q 30
bridge-group 30
!
int f0.10
encapsulation dot1q 10
bridge-group 10
!
int f0.20
encapsulation dot1q 20
bridge-group 20
!
int f0.30
encapsulation dot1q 30
bridge-group 30

Then just make sure your AP are connected to trunk ports allowing vlan 1,10,20,30

Thanks Steve,

Very helpful.

I just read another useful post "Autonomous AP and Bridge Basic Configuration Template" though not exactly refers to my configuration.

You mentioned that only one SSID (e.g. wirelessbridge) is required for the bridge link, is that SSID be associated to dot11radio0 (or dot11radio1 for 5GHz bridge) instead of the sub-interface?  Do I need to map the bridge link SSID to any vlan?

Int dot11radio0  or  Intdot11radio1

    ssid wirelessbridge                                 

    station-role root or non-root

    bridge-group

    no shut

dot11 ssid wirelessbridge

   vlan x                                    <<<<<< do I need this?

   infrastructure-ssid

Thanks

yes, you would want that linked to which ever VLAN is 'native'
