IP Address Enter the subinterface IP address. Netmask Enter the network mask associated with the IP address. The default value is 255.255.255.0. If several addresses are applied to an interface and these addresses are in a common network, they must use a common subnet. The system does not support supernetting. Interface Choose a port location from the Interface drop-down list:
