In a WLAN network, when engineers configure the DHCP server, they need to pay attention to whether the WAC and the AP are in the same network segment. If they are in the same network segment, the DHCP server does not need to configure the option 148 field and the AP can also discover the WAC by broadcasting. If the WAC and the AP are not in the same network segment, the DHCP server must configure the option 148 field to specify the IP address of the WAC for the AP, otherwise the AP will not be able to discover the WAC.
