/etc/network/interfaces (vlan) - vlan extensions for the interfaces
/etc/network/interfaces contains network interface configuration information for
(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
iface eth0.1 inet static
iface vlan1 inet static
iface eth0.0001 inet static
iface vlan0001 inet static
# We don't have br support out of the box
iface br0.2 inet static
# Aliases are ignored
iface br0.2:1 inet static
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.
