MAC address bypass not working on Catalyst 9800-CL Software version 17.3.3

Hello,

 

I have catalyst 9130AXI connected to Catalyst 9800-CL (OS 16.12.5) installed on my Virtual Machine.

I configured Mac Address Bypass on this version and it works well, but there are problem with 5Ghz radio, it keep restarting 5Ghz radio on catalyst 9130AXI. the AP show this error before restarting the radios:

beacon stuck.jpeg

[*03/25/2021 10:17:59.8668] DOT11_DRV[1]: Beacon Stuck - reset radio for recovery

[*03/25/2021 10:17:59.8669] DOT11_DRV[1]: *** Triggered FW assert for radio failure (Beacons stuck)

[*03/25/2021 10:17:59.8669] 

[*03/25/2021 10:17:59.8736] DOT11_DRV[1]: *** Resetting Radio 1

[*03/25/2021 10:17:59.8736] DOT11_DRV[1]: Stop Radio1 - Begin

[*03/25/2021 10:17:59.8898] DOT11_DRV[1]: Stop Radio1 - End

 

and so I try software version for 17.3.3 for this implementation.

in this software version, the issue on 5Ghz radio is solved but there is another issue on Mac Address Bypass.

I've configure Mac Address Bypass on 1 SSID, but I unable to connect my Laptop(with registered mac address).

On the vWLC, there are some log that show this error:

Apr 16 03:20:19.934: %SESSION_MGR-5-FAIL: Chassis 1 R0/0: wncd: Authorization failed or unapplied for client (94db.c903.9372) on Interface capwap_9000000c AuditSessionID 0000000000001061D89DEDDE. Failure reason: Authc fail. Authc failure reason: AAA Server Down.

Please advice regarding this issue.

Thanks.

Hi All,

I want to give my update regarding this issue.
it turn out that it was a bug on 17.3 software (https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv43870) that the entry format for the mac address must be without any separator.

Thanks all for all your suggestion and input.

Hi marce1000,

 

thanks for the reply.

we've overcome the problem regarding "Beacon Stuck" on 5Ghz radio by installing version 17.3.3.

but there are another problem occur as I mention above regarding Mac Address Bypass.

do you have any advice regarding issue with Mac Address Bypass?

 

The error message TELLS you what the problem is: "AAA Server Down".

So check your config and work out why the WLC cannot connect to your radius server! config/routes/ACL/source interface etc

Did anyone manage to fix this MAC filter problem, or found a version in 17.x that works ?

Failure reason: Authc fail. Authc failure reason: AAA Server Down.

 

I'm also following the steps in this article, https://0x2142.com/how-to-catalyst-9800-mac-filtering/

Same error.

I have done exactly the same create the MAC address list local within wlc, so the error message seems like a bug.

I just had a read of CSCvz30708 and rebooted the wlc as per the resolution.

Still no good.

 

Example here's the whole chain of events when a device attempt to connect.

Strange error to have when the AAA is local wlc itself.

Unfortunately can't try to upgrade higher version, old access point this is the highest it can support.


Then I think you need to open a case with Cisco TAC and keep us updated on what they say.

Brilliant this is exactly the solution.

 

Cisco should have coded the error log much better, it's no MAC matching, not AAA server down.
