i have controller 5508 version 18.104.22.168 and AP 1242
the controller is connected to N7k with 4 fiber cables and configured portchannel from N7k and enable LAG in the controller .
all APs are working fine and register in windows dhcp server by option 43
but the problem appears in the DHCP Server . I note the presence of crash IPs in the AP dhcp scope when i restarted controller for test or
diable and enable ports for port-channel in the N7k ..
Not sure what you mean by "crash IPs" can you further explain please?

Crash ip meaning ( the IP was used by AP appears as crash IP in the DHCP when the APs power off and power on )
This affects the number of IP reservated for AP scope in the DHCP server .
when all AP is power off and power on , some access points is not registration in the controller because
threr is no enough ip in the DHCP server.
