mobility group. You can configure up to 12 Wireless Services Module (WiSM) blades in one mobility group. Therefore, up to a maximum of 3600 access points (APs) are supported in a single mobility group.
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:
1.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.
2.The WLC shows the virtual address to the WLAN clients and the management interface address upstream.
3.The WLC acts as a DHCP relay (Bootstrap Protocol [BOOTP] relay) device.
Note: When the internal DHCP server is used, the lightweight access point (AP) should be directly connected to the WLC. Also, you cannot share a DHCP scope between two or more WLCs.
