Controller command

[Wifi_Eshwar92]

Hi All,

I have enabled this "config ap dtls-wlc-mic SHA1/SHA2" on the controller for this error "*AP has SHA2 MIC certificate - Using SHA2 MIC certificate for DTLS." Now i want to remove that command. How to disable it? will this command affect the aps joining in future or other aps if rebooted ? Thanks!

I dont think you can disable that...

either you need to enable SHA1 or SHA2!!

Yeah couldnot see command to disable it.. Any idea will it affect already joined aps in the event of reboot?

[Sandeep Choudhary]

did you configure SHA2 or SHA1 on WLC ?

What was earlier configured ?

How to check that.. what all certificates need for ap to join.. ? 

by the way we have many 1242 models which are pretty old..

ohk then old AP must have SHA1 certificates.

So if you configure SHA2 on WLC then these old AP will have trouble to join again after reboot.

So better to keep SHA1 on wlc.

Thanks for the response..

okay.. it sounds like only one certificate will be enabled on the controller? I mean, wont it have all the certificates enabled if we give those command? I have actually given both the commands in order.. SHA1 and then SHA2 as well.. (is there any other certificates aps will come up with- just curious :))

I could also try reboot one ap and test, but it seems like it will take time ...

Hi,

As far as I Know: The WLC supports SHA-2 certificates since release 8.0.100, so at this moment this is the only release where this is supported on.

Now running on 8.0.140.0.. may be i can try rebooting 1 ap and see if any issues.. then revert back to SHA1 if needed.. I will update back here,,

Many thanks for your time
