VLANs in /etc/network/interfaces ================================ Check the vlan-interfaces(5) man page and make sure you set vlan-raw-device in your interfaces stanzas. You can omit the hint in some cases, but it's best to always have the keyword. MAC-VLAN ======== You need a kernel with the MAC-VLAN driver to use macvlan_config. MAC-VLAN support was merged in the Linux kernel for version 2.6.23. Aliases ======= Interface aliases are completely ignored by the VLAN scripts; see vlan-interfaces(5).
