Reset NTP on WLC

ritchie65

Hi all,

We have an issue where some APs are not joining a WLC (5508).  We suspect a MIC cert issue and have already disabled the MIC cert check on the WLC.

Next step we want to do is to disable NTP and reset the date time to a past value to see if those APs join the WLC

Can anyone confirm if this affects/resets the existing APs already on the WLC?    ie. temp loss of service or APs reset

 

Thanks

If the APs have already joined the WLC, temporarily disabling NTP and resetting the WLC date will not affect AP operations.

As long as the AP already working, they should work as expected.

what is the full Logs (when you connect the console to AP and why its not joining ?) 

agreed NTP is one of the causes of the issue (not necessarily that is an issue may be) - is this AP not joined a new one or an OLD one?

check the compatibility list with Code if they are new.
