I have set the local DHCP scope with "option 43" on the core switch and I can see APs are getting IPs properly. The communication between remote WLC and APs is good however WLC is not detecting remote APs.
Device details:-
WLC: Model: AIR-CT5508 K9
AP: Cisco C9120AXI-B
The same WLC already managed many APs locally as well as remotely.
