I've four devices in my lab environment:
1x WLC 2112
The C3500 is in the middle,
directly connected with the WLC and the C3524XL. Each of them in a trunk.
The AP is conected to the C3524XL.
The AP has got an IP from the DHCP server who is running on the C3350.
So I can ping every device, also the WLC/AP from a PC which is directly connected to the C3550. I also can ping the AP from the WLC.
But, the AP is still not associated.
I can't find the AP, also not when I try to add the AP by the MAC-address.
Please can somebody help me to find my mistake ?
Just do the following:
AP#lwapp ap controller ip address
You need to be in enable mode and NOT configuration mode. Your AP should be running the LWAPP Recovery (aka RCV) image.
Hope this helps.
