D-Link DES-3326 Configuration Manual page 8

Once again in this example we have used the fist octet for the interface name.
The IP address is the IP address of the the switch in that particular subnet, we
have choosen 192.168.0.250 MASK 255.255.255.0. The VID is the PVID set
in the VLAN configuration previously done. After the config is applied, the
screen will show you the configuration as in fig 12.
Ensure all the configurations have been applied, check the IP interfaces
addresses. If all looks okay return to the main menu and save the
configuration.
