If routing is enabled, we strongly recommend that you define a loopback interface on the switch. By creating a loopback interface, you can control which routing interface the wireless function uses for its IP address when multiple routing interfaces exist. This can avoid discovery problems for the discovery modes that use the IP address of the WCS. With the loopback interface, the IP address of the wireless function is always the same.
NOTE: In this context, the loopback interface does not refer to the loopback interface with the 127.0.0.1 IP address. When you configure a loopback interface for the wireless interface on the switch, it is essentially a permanent logical inter- face and cannot have an IP address of 127.0.0.1. You must create a dedicated subnet for the loopback interface, and other devices on the network must be able to contact the IP address of the loopback interface.
The advantage of defining a loopback interface is that the interface never goes down. The disadvantage is that network configuration is more complex because the loopback interface is located on its own subnet and the rest of the network must know how to get to the subnet.
The network must have routes between the WCS and the APs you want it to manage. The APs must be able to ping the IP address assigned to the wireless interface on the WCS. You configure static routes on the switch through the configuration pages under LAN >
L3 Features > Router.
The following procedures show an example of how to enable routing and configure a IP address on a routing or loopback interface by using the CLI:
1. Log on to the CLI and switch to Global Config mode:
2. Enable routing.
