Configuring the Loopback IP Address
The loopback IP address is a logical IP interface that is used by the WFS709TP to communicate
with APs. If you do not configure a loopback address for the switch, the IP address of the lowest-
numbered VLAN interface (typically VLAN 1) is used.
The WFS709TP uses the loopback address as its IP address for terminating Virtual Private
Network (VPN) and Generic Routing Encapsulation (GRE) tunnels, for originating requests to
RADIUS servers, and for 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 make use of this interface, ensure that the IP address is
reachable through one of the VLAN interfaces. It should be routable from all external networks.
You can modify or delete the IP address of the loopback interface on the WFS709TP. However,
you cannot delete the loopback address if there is no IP address configured for the VLAN 1
interface; if you attempt to do so, you will be prompted for a new IP address for the VLAN 1
interface. You also cannot delete the IP address for the VLAN 1 interface if there is no loopback
address configured; you will be prompted for a new loopback address.
To configure or change the loopback IP address on the WFS709TP:
Note: The route has not yet been added to the routing table.
Note: Any change in the WFS709TP’s IP address requires a reboot.
