non-root bridge association problem

fopravil — Sat, 03 Jul 2021 20:16:36 GMT

I have an installation using Cisco 1242 Access Points (IOS) as bridges

in 5Ghz band, and as AP in 2,4 GHz band. Sometimes I get problems

with the non-root bridges, after mains outage, they will not

associate to the root bridge. Command "dot11 do 1 carrier busy"

issued to the non-root bridge helps, but sometimes I have to use it

several times. Have anybody any idea about possible cause?

Thanks

Hi Frantisek,

what IOS version do you use?

In the past i solved some issues with a actual or older IOS image!

Have a look on the release note if you try to use an older image.

I have running the above mentioned config with 1232 APs and a 12.3(8)JEA image.

Best regards,

Frank

Hi Frank,

I am running 12.3(8)JA2; I is a good idea to try new sw version, I will try it (probably during next week).

I suspect there is some interference causing this effect, but i have no suitable measurement equipment to prove it.

Best regards

Hi Frank,

I think I have found the reason of my troubles. It is the following configuration command:

(interface Dot11Radio1)

world-mode dot11d country CZ outdoor

which is not only not-needed on the non-root bridge AP, it prevents associating the non-root bridge to the root-bridge AP. It does not cause the troubles on each root non-root couple. The troubles are more frequent with IOS version 12.3(11)JA or 12.3(8)JEA than with 12.3(8)JA2.
