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.
