Configuring the Loopback IP Address
The loopback IP address is a logical IP interface that is used by the controller to communicate with APs. The
loopback address is used as the controller’s IP address for terminating VPN and GRE tunnels, originating requests
to RADIUS servers and accepting administrative communications. You configure the loopback address as a host
address with a 32-bit netmask. The loopback address is not bound to any specific interface and is operational at all
times. To use this interface, ensure that the IP address is reachable through one of the VLAN interfaces. It should
be routable from all external networks.
You must configure a loopback address if you are not using VLAN1 to connect the controller to the network. If
the loopback interface address is not configured then the first configured VLAN interface address is selected.
Generally, VLAN 1 is the factory default setting and thus becomes the controller IP address

Configuring the Controller IP Address
The Controller IP address is used by the controller to communicate with external devices such as APs.
Note: If you are using the loopback IP address to access the WebUI, changing the loopback IP address will result in loss of
connectivity. Dell recommends that you use one of the VLAN interface IP addresses to access the WebUI.
