Figure 9-4 ARP Request
The AP receives the ARP and sees its MAC address. It verifies the frame check sequence
(FCS) in the frame and waits the short interframe space (SIFS) time. When the SIFS time
expires, it sends an ACK back to the wireless client that sent the ARP request. This ACK is
not an ARP response; rather, it is an ACK for the wireless frame transmission.
The AP then forwards the frame to the WLC using the Lightweight Access Point Protocol
(LWAPP), as illustrated in Figure 9-5.
