I'm trying to set up the 9120axp running 17.2.1.11 to connect to a new 9800 L_F WLC running 16.12.01.
On the AP Im getting ( Discovery response from MWAR 'HOSTNAME' running version 16.12.1.0 is rejected)..
I have created the wlc management address on the wlc of 10.0.0.2 and the I have the AP connect to a L3 switch with dhcp configured so the AP now has an IP and a default gateway.
Any help you can provide would be gratefully received.
Below is the log for the 9120 AP.
