Hi,
I have the WLC C9800-L-F-K9 . The Aps AP C9115AXI-E and AIR-AP1562E-E-K9 are not getting registered to the WLC.
The Ap is pingable from wlc and WLC is pingable from AP.
On console, I am getting teh below logs.

Do you mean DHCP option 43 code?
The WLC and Aps are in same subnet.. so in that case, we need not define option 43 ascii code right.

The country code is defined already..
All these are new APs just unboxed it.. So, I am looking for any other solution except factory reset.

I can give a try on making it factory defaults.. But i have rebooted the Ap and bounced the switch ports several times. no luck.

I found issue here
CISCO-CAPWAP-CONTROLLER.ori.orica.net.<- are you sure the net is your domain usually the domain is end with .com which is root here it think the DNS can not resolve the name-ip of WLC.
connect PC to SW and use lookup to find if PC can resolve the ip of control using DNS server.
12-08-2020 07:46 AM
yes. . .net is the domain name and i have verified its configured correctly
12-08-2020 08:19 AM
Do you check by connect pc and do lookup?

let explain to you why we need to check DNS
there are three discover method
DNS,
DHCP,
and broadcast
you config DNS and not config DHCP and broadcast is by default.
it seem that DNS is failed either
1- AP can not connect to DNS server
2- DNS server have A record for WLC VLAN not AP manager
3-DNS behind FW this FW change the IP address "NAT it"
so we can check this by PC connect to same SW that AP connect to it,
PC will get ip address from dhcp
PC do lookup for DNS, we will see ip is it same as aspect or not
