I am testing Cisco 9800 series WLC with software version 17.3.3, 9115 AP is in local mode.
Issue: When I am using external DHCP server , also added the ip helper address command on upstream switch then all clients stuck in IP learn state.
If I use internal DHCP server then it working.
What could be the issue ?
