NAME
/etc/network/interfaces (vlan) - vlan extensions for the interfaces(5) file format
DESCRIPTION
/etc/network/interfaces contains network interface configuration information for the
ifup(8) and ifdown(8) commands. This manpage describes the vlan extensions to the stan‐
dard 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 CREATION
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 fol‐
lowing 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.
