Access Point 2702I not joining C5508 WLC

Adnan Jameel — Fri, 09 Sep 2022 15:07:41 GMT

Hi,

I am facing the issue that 2702I AP is not joining C5508 controller. Initially all APs were not joining due to country code and certificate validity date. Then I resolved the country code issue and applied config ap cert-expiry-ignore {mic|ssc} enable. After that few APs have joined but still some APs facinf not joining problems. Below are APs and WLC logs

Since Cisco SHA1 device cert was expired in WLC (can be seen in above wlc certificates) then I set year 2014 in controller, all aps started to download image and joined the WLC. The reason is MIC expired. What's the work around for MIC update? Because at the end it would be necessary to keep WLC in 2022.

>...config ap lifetime-check mic ssc disable

Note that according to : https://bst.cisco.com/bugsearch/bug/CSCut75441 . the particular command may have the reverse effect what is intended , have a try with >...config ap lifetime-check mic ssc enable

@Mark Elsen he has already mentioned using the "fixed" version of the command.
@Adnan Jameel just make sure you follow ALL the instructions in the field notice closely.
https://www.cisco.com/c/en/us/support/docs/field-notices/639/fn63942.html
Make sure you're running the latest version of code with all fixes (8.5.182.0) and with the config workarounds applied and after disabling NTP and changing the time (as you did) then all APs should be able to join, download new code and apply the config change and then should work when time goes back to NTP. If they still aren't joining it could be another problem or a faulty AP. Always remember to try doing a factory default reset on the AP and remember after default it can only join and pick up the config change while the time is "valid" according to the cert (because the config change is lost).
