I can't see AP on WLC

Hi,

I'm trying to find out why my APs can't join to WLC. Both are in the same Vlan, AP has a static IP (the same subnet).

Thanks for any advice

I can't see AP on WLC

What type of AP are you using?  What code is on the WLC?

Do me a favor and run debug capwap errors enable.  and I bet you'll see a reference to MESH.  If you do, add the mac address of the AP to the macfilter.

Hi Steve,

the debug output above was taken after below commands:

debug capwap events enable

debug capwap errors enable

debug capwap detail enable
