Q. How does DHCP work with the WLC?
A. The WLC acts as a DHCP relay device. The WLC does the DHCP relay through the
virtual interface. Typically, the 1.1.1.1 address is assigned to the virtual interface. This
address can be any address. However, it must not be a routable address.
These are the events that occur:
The WLAN client sees the administration−defined virtual address as the DHCP
server address. The recommended address is usually 1.1.1.1 because this address is
not normally a routable network address.
1.
The WLC shows the virtual address to the WLAN clients and the management
interface address upstream.
2.
The WLC acts as a DHCP relay (Bootstrap Protocol [BOOTP] relay) device.3.

directly connected to the WLC. Also, you cannot share a DHCP scope between two or more
WLCs.
