Cisco Systems 3750G manual

Step 21 Enter the IP addresses of the primary and the optional secondary DHCP servers that supply IP addresses to the controller AP-manager interface. If the AP-manager interface is on the same subnet as the management interface, the AP-manager interface uses the same DHCP server IP address as the management interface.

Step 22 Click Next. The Virtual Interface Configuration page appears.

Step 23 In the IP Address field, enter the IP address of the controller virtual interface to be used by all controller Layer 3 security and mobility managers. You should enter a fictitious, unassigned IP address, such as 1.1.1.1.

The virtual interface is used to support mobility management, DHCP relay, and embedded Layer 3 security such as guest web authentication and VPN termination. All controllers within a mobility group must be configured with the same virtual interface IP address.

Step 24 In the DNS Host Name field, enter the DNS host name if your controller uses an externally generated web authentication ID certificate that includes a DNS hostname.
