I have 1 WISM and 1 4402-50 and running on OS4.1.185
They name are WISM-1, WISM-2, 4402-50.
The AP was got ip by DHCP server.
I have configure primary wlc is 4402-50, secondary wlc is WISM-2 and tertiary wlc is WISM-1.
But, the AP1010 always join secondary and tertiary, it's not to join primary.
Have anyone to same issus?
Well, it looks like there isn't a join response.... again, do you have any ap's on the wism's in which you can move to the 4400 or the other way around. This will identify if mobility is working.
If you don't have any ap's on the 4400, then try to ping the AP manager IP address.... you shouldn't be able to. Disconnect the 4400 from the network and see if you can ping that address. You might have a duplicate address for the AP manager which might cause the output you are seeing.
