What does the DHCP Required field under a WLAN signify?
A. DHCP Required is an option that can be enabled for a WLAN. It necessitates that all clients that associate to that particular WLAN obtain IP addresses through DHCP. Clients with static IP addresses are not allowed to associate to the WLAN. This option is found under the Advanced tab of a WLAN. WLC allows the traffic to/from a client only if its IP address is present in the MSCB table of the WLC. WLC records the IP address of a client during its DHCP Request or DHCP Renew. This requires that a client renews its IP address every time it re-associates to the WLC because every time the client disassociates as a part of its roam process or session timeout, its entry is erased from the MSCB table. The client must again re-authenticate and reassociate to the WLC, which again makes the client entry in the table.
