Hi Sushil,

The AP you are referring to can be modified to add an "A" Radio. Then you could configure the two radios (B/G and A) to perform the differing functions;

Cisco Aironet 1200 Series Access Point Hardware Installation Guide,

Upgrading the 5-GHz Radio Module

Link-Role Flexibility

Autonomous access points can function as an access point or bridge, whether set up as a single-band or dual-band platform, allowing each radio to be individually configured as an access point repeater, root bridge, non-root bridge, or workgroup bridge, enabling a broad array of applications.

Hope this helps!

hi mate thanks a lot for ur reply. u mean to sa i can do the thing i was asking right without buying any radio module for the same.

so i should configure one radio on b/g and other radio as a right . then i should be able to use it right.

pls confirm on the same.

hi mate i checked on my acces point. it;s a 1231 access point model.

and in the interface tab i can see the ethernet interface and the radio0 interface . and it also says radio 1 not installed.

does it mean i will have to buy a seperate radio1 for using both the functions of access-point and bridge at the same time.

can u pls help me on this.

waiting for ur reply.

Hi Sushil,

Yes, sorry my first reference was not very clear. Your 1231 only has a b/g radio so the link I sent shows how to add the newly purchased "A" radio module (as nicely noted by Chris). Then you will be able to set things up the way you want :)

Hope this helps!

Hi Sushil,

You can order the "A" Radio seperately. Here are the two part numbers. One is an Integrated Antenna and one has Dual connectors for use with External Antennas;

Integrated diversity antennas.


Regulatory domains: (x = regulatory domain)

• A = FCC

• C = China

• E = ETSI

• I = Israel

• J = Japan

• K = Korea

• N = North America (excluding FCC)

• P = Japan2

• S = Singapore

• T = Taiwan

Dual RP-TNC connectors. Antennas sold separately.


Hope this helps!

hi rob thanks for ur help and ur support mate.

mate i would like to ask u one thing.

i read in the cisco doc we can also use the access-point a root or non-root bridge with clients.

for using the access-point as above do i still need 2 radio;s on the access-point .

can u help me on this

thanks a lot mate.

Hi Sushil,

You are most welcome :) If you wanted to setup a Root-Bridge with clients you would really want the two radios. For example you can use the A radio for Bridging and the b/g radio for client connections;

Set the Non-Root with this config ***Non-Root Bridge with Wireless clients***;

Q. What devices can associate with a bridge?

A. Root Bridge:

Accepts associations and communications with non-root bridge devices and clients.

Does not communicate with other root bridge devices.

Communicates with multiple non-root bridge devices.

Non-Root Bridge:

Can associate and communicate with root devices or clients.

Does not communicate with other non-root devices, unless the other non-root devices communicates with the root bridge.

Note: Both the root bridge and the non-root bridge will service clients only if the role in the radio network Root Bridge with Wireless Clients or ***Non-Root Bridge with Wireless clients*** is supported by the bridge and is enabled.

Nice Step by Step;

Hope this helps!

hi rob thanks a lot man for ur detailed explaination man.

mate can u pls tell me when we can have bridges support having clients connected to them is there any benfit of clients connecting to pure access-points.

i mean is there any different in that. or is that when the bridge is supporting clients one of it;s radio is working as a access-point and other as bridge.

pls help me understand this.

thanks a lot once again.
