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
In the WebUI
1. Navigate to the Configuration > Network > Controller > System Settings page and locate the Loopback
Interface section.
2. Modify the IP Address as required.
3. Click
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.
4. Apply.
5. Navigate to the Maintenance > Controller > Reboot Controller page to reboot the controller to apply the
change of loopback IP address.
6. Click Continue to save the configuration.
7. When prompted that the changes were written successfully to flash, click OK.
8. The controller boots up with the changed loopback IP address.
In the CLI
(host) (config) #interface loopback ip address <address>
(host) (config) #write memory
Enter the following command in Enable mode to reboot the controller :
(host) #reload
