/etc/network/interfaces (vlan) - vlan extensions for the interfaces(5) file format
/etc/network/interfaces contains network interface configuration information for the ifup(8) and ifdown(8) commands. This manpage describes the vlan extensions to the standard interfaces(5) file format. Primary extensions exist to make and destroy vlan interfaces, secondary extensions exist for ipv4 interface manipulation which are generally needed when using (a lot of) vlans.
Vlan interface definitions exist of the vlan interface name, and an optional ´raw-device´ parameter. Vlan interfaces are numbered 1 to 4095. You have the option to have interface names zero-padded to 4 numbers, or just the plain digits without leading zero. The following example shows four ways to create a vlan with id 1 on interface eth0. They all result in different names. iface eth0.1 inet static address 192.168.1.1 netmask 255.255.255.0 iface vlan1 inet static vlan-raw-device eth0 address 192.168.1.1 netmask 255.255.255.0 iface eth0.0001 inet static address 192.168.1.1 netmask 255.255.255.0 iface vlan0001 inet static vlan-raw-device eth0 address 192.168.1.1 netmask 255.255.255.0 # We don't have br support out of the box iface br0.2 inet static vlan-raw-device br0 address 192.168.1.1 netmask 255.255.255.0 # Aliases are ignored iface br0.2:1 inet static address 192.168.1.1 netmask 255.255.255.255
EXTRA IFACE OPTIONS
Usually someone who uses vlans also wants to do some other manipulations with the ip stack or interface. vlan-raw-device devicename Indicates the device to create the vlan on. This is ignored when the devicename is part of the vlan interface name. ip-proxy-arp 0|1 Turn proxy-arp off or on for this specific interface. This also works on plain ethernet like devices. ip-rp-filter 0|1|2 Set the return path filter for this specific interface. This also works on plain ethernet like devices. hw-mac-address mac-address This sets the mac address of the interface before bringing it up. This works on any device that allows setting the hardware address with the ip command.
