Dear all
We have two controllers 7210 (one master and one standby master) with AOS 6.5 and starting to deploy AP 305 but we encounter some issues :
about half of the AP cannot join the controller. (yes some can join the controller and some cannot).
- First thing to mention : AP were previously deploy in another project (different AOS version : 8.5, diffrent IP parameters ...), but no data were hard written on AP (no manual master setting) . We do not put back these AP in the default group and send them to prod with the previous configuration. (As we were thinking that it would get through the normal process : get IP adress and master ip adress from DHCP => join the controller => make firmeware upgrade /downgrade => get ready to be provisionned on controller)
- From the switch AP are up and DHCP exchange is correctly seen.
- Controller and AP are on the same layer 2.
- AP discover controller throught DHCP method (option 43) so we checked this : AP get IP, get the right information from controller offer.
There is no ADP, no DNS discover, no manual configuration.
- There is no log on controller for these AP
So from this diagnostic we understand that AP are electrically powered get an IP adress receveid the master IP adress but somehow refuse to join it.
Is somebody else ever getting throught something like this ? Is there any way to force AP to join a controller or reset it without serial connection ? (we already try to reboot AP from PoE shutdown).
Could it be that AP get stuck with the previous configuration ?
I will be very grateful if I could get help.
Thanks and Regards
