- Post the ap boot process and check the logs on the EWC too when the access point tries to join.

Based on the title I suspect the answer here was that WS-C3850-48P cannot run EWC so there is no way a 9120 could ever join a WS-C3850-48P. EWC is only supported on (some) Catalyst 9xxx APs and on some Catalyst 9x00 series switches for SD access (fabric) only (no more standalone EWC on Catalyst switches)

Thanks for the comments. Actually, it required to configure the ip address AP since i only configured the ip address for EWC.

So something still doesn't compute ...

And for IP addresses - DHCP always comes in handy for APs and then you can use option 43.
