I am having issues adding additional AP's currently i have 15 aps no problem but trying to add 2 more and no luck , they do show under statistics ap join with ip addresses assigned but status not joined.

also found this:

Reason For Last Unsuccessful Attempt

Layer 3 discovery request not received on management VLAN

[Sathiyanarayanan Ravindran]

Hi,

Check whether the WLC is reachable from the AP. Also please share the Model of AP which you are trying to join.

[bdobruna09]

Model of the AP is AIR-CAP3502E-A-K9 and you mean connect console to the ap and try to ping the WLC ?

[Sathiyanarayanan Ravindran]

Yes, Try to ping the WLC from the AP. Also check whether you are getting any error message on the console. If possible post those error logs.

Is this new AP connected to Same Access Switch , same IP addres Range ?

how is the IP address allocated to these AP ? from DHCP  ? 

what is the AP working IP range, what is new AP IP range ?

[bdobruna09]

@balaji yes AP is on same switch and same range , the switch port is trunk and i see it under the ap not associated to the controller.Yes its from dhcp and then i will assign static.

[RaffyLindogan]

This error "Layer 3 discovery request not received on management VLAN" could mean: 

 1. WLC is not added on DHCP option

 2. Vlan may not be allowed all the way to the respective trunk links

Can you send the logs when you console to the AP.

Cheers

Hi mate,

Can you enable the debug on WLC.

Reload the AP once debugs are enabled.

And please post the results here.

Thanks.

WLC: 

 debug mac add <ap mac>

 debug client <ap mac>

debug capwap events events enable

debug capwap errors enable

AP:

 show log

I figured out as it sounds very strange, i changed the port where the AP was connected not to be Trunk and i was able to join the WLC then changed it back to trunk and good to go.

thank you all

What happens if you configure NTP on the controller?
