C9800L is connected to the Core Switch 9500, and the AP is connected in VLAN 100. A VLAN 100 SVI has been created in the Core Switch and an IP helper has been configured. IP addresses are successfully being released in VLAN 100 without any issues. The IP address has also been released for the AP and it has joined with the controller. However, the WLC is not releasing an IP address for clients.
In the C9800L, VLAN 100 is configured, not SVI. The DHCP Server IP is enabled in the policy, but IPv4 DHCP required is disabled.
Please assist me in resolving this issue.
