Wireless Access points wont join controller due to date/time

Hi All,

 

Having issues with my 2500 series controller.

 

Access points will disconnect from the controller and not re-connect until I set the controller date to be within the set period that the access point seems to have set on it.

 

Example debugging log.

 

*spamApTask5: Jan 21 15:29:35.758: sshpmGetIssuerHandles: ValidityString (current): 2016/01/21/04:59:35

*spamApTask5: Jan 21 15:29:35.758: sshpmGetIssuerHandles: ValidityString (NotBefore): 2018/06/12/13:15:18

*spamApTask5: Jan 21 15:29:35.758: sshpmGetIssuerHandles: ValidityString (NotAfter): 2037

 

 

Is there some kind of way I can get ALL my ap's to join the controller regardless of the date/time?

 

This is an issue because some of my ap's seem to stop at 2018, and some only start working at 2018 so I always seem to be having to constantly adjust this date/time to keep the majority of them connected.

 

Thanks

 

Jason

Time and date has to be correct because APs have an SSC.

As @Leo L said APs have a certificate that should be valid so the only way to fix that is to generate new certificates for all APs.

What version of code?

What AP models?

Either way the answer is likely to be obvious once you've had a long slow read and re-read of https://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63942.html and followed all the steps in the right order.

Importantly you need code version with the fix/workaround and the config applied.

Then you may need to play with date to get them joined.

Once you've got them joined they can update fixed code version and config and once they're all done you should be able to sync to NTP again.

Helpful tip... next time, post the ap model and controller firmware.  Also, the output from the ap via the console helps with troubleshooting when an access point fails to join.  It does seem like you might have old ap's that the cert has expired (10 years for manufactured date).

Thanks for the replies guys.

I will have to read through those documents.

 

Software Version of controller is 8.0.133.0

 

We have a number of AP models.

 

AIR-LAP1142N-N-K9's

AIR-CAP1532E-E-K9's

And

AIR-CAP1532I-Z-K9's

So the field notice definitely applies. You should get on to the last 8.3 release  8.3.150.0:

https://software.cisco.com/download/home/283848165/type/280926587/release/8.3.150.0

https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html#ctr-ap_support

It's out of support but the last release that will support your 1142 APs.

And then apply the config for ignoring the expired certs, get the APs joined (by turning back the date) then they'll download the new code and config workaround and then you can set time back to normal and the rest should join and update.

Take a look at what @rrudling posted.  The issue that you will have is obtaining the software if you don't have support.  You can reach out to TAC to see if they can provide the image to you per this document.  Also search the forum for "ap certificate expiration" and see what the others have done to fix the issue.
