WLC 4402: %APF-1-NOT_ADV_SSID_ON_AP

Hello!

We use a small wireless-infrastructure with a WLC 4402 and 15 accesspoints.

The controller works with version 4.2.61.0.

Yesterday we got this logging-message:

apf_spam.c:934 APF-1-NOT_ADV_SSID_ON_AP: Not advertising SSID <ssid> on AP <MACaddress> due to radio policy.

I didn't find anything about the failure at cisco.com or the www.

There is only a reference to Cisco TAC.

Does anybody know something about this failure?

Thanks a lot!

Sven

Re: WLC 4402: %APF-1-NOT_ADV_SSID_ON_AP

There is no impact. The system is just informing you that a device is trying to connect to protocol that is not part of the WLAN's policy. If you had another ssid that you need both protocols, then you wouldn't be able to disable the radio and you would see the errors again on that WLAN you specified a policies.

Probably you have choosen B/G only for the WLAN,

so once you create the SSID it try to broadcast it on A radio which is not

enable in the Policy. The reason it tries to bradcast it on the A radio is

because the AP have the A radio Administratively UP.

So it's not a failure, but a radio policy..

You are right!

All the A-Radios are admin status enable but operational status down.

I will disable all the A-Radios on all accesspoints because we don't need them.

Thanks!

Now I disabled the A-radios on the accesspoints, but the failure is the same.

What does this message exactly mean?

Will the AP working with the SSID on the B/G-radio or has the AP no active SSID now because of the policy violation?

Thanks!

Well if you disable the 802.11A radio, change the policy to all on that ssid and see if your messages disappear.

Yes, after setting the policy to "all" the messages disappear.

fella5, do you know something more about this failure? Is it cosmetic or is there any impact about it?

Thanks!

Re: WLC 4402: %APF-1-NOT_ADV_SSID_ON_AP

We got the response from Cisco, that there is an impact when the failure comes up.

The impacts are variability of the signal level and a smaller signal reach.

With the Software v5.1 the bug should be patched.

Up to the release the workaround is to change the policy from the SSID to "all".

Do you have the bug id?

Re: WLC 4402: %APF-1-NOT_ADV_SSID_ON_AP

sure...the bug ID is CSCsl91623.

In the decription Cisco calls the accesspoints 1510 only for this problem.

but the case owner said, that the failure applies to the 1242AG, too.
