What Is the Registration Procedure When a Fit AP and an AC Are Connected Directly or over a Layer 2 Network?

The following figure shows the procedure that a fit AP registers with an AC when they are
connected directly or over a Layer 2 network.

The registration procedure is as follows:
1. The fit AP obtains a Fit AP IP address and DHCP server IP address from the DHCP
server.
2. The fit AP broadcasts a Discovery Request message at Layer 2 to attempt to associate
with an AC.
3. After receiving the Discovery Request message, the AC checks whether the fit AP has
the access right. If the fit AP is authorized, the AC replies with a Discovery Response
message.
4. The fit AP downloads the latest software version from the AC.
5. The fit AP downloads the latest configurations from the AC.
6. The fit AP exchanges service data packets with the AC.
