If the system is connected to a switch, the switch will notify the system about the VLAN
information defined on the switch.

You need to configure the network settings of the system manually if any of them are not
provided by the DHCP server. For more information on configuring network settings manually,
refer to Configuring Network Settings Manually on page 52.
