The network interface can be configured as a VLAN using the following string format:
"[parent_interface].[vlan_id]". Once the VLAN interface(s) are configured, they must be enabled on the parent network interface (e.g. "eth0") using the
SetVlanIds() method. VLAN interfaces use DHCP by default. They are supported on Series 3 players (XTx43, XDx33, HDx23, LS423, HO523) only.
