Today i was playing around with ethernet adapters and vlans in Alpine Linux. I tried to give the interfaces arbitrary names.



After looking at the source i had the following example working



Ethernet adapter named lan01 configured as DHCP client and a VLAN on this adapter named lan-test on VLAN ID 100



My /etc/network/interfaces:



auto lo
iface lo inet loopback

auto lan01
iface lan01 inet dhcp
hostname alpine

auto lan-test
iface lan-test inet static
vlan-id 100
vlan-raw-device lan01
address 10.10.0.1
netmask 255.255.255.0


ifup and ifdown in Alpine Linux uses busybox.



Nowhere in any documentation i found the option vlan-id. However the vlan-raw-device is found in most documentation/man pages.
So this brings me to the question: Why is this option not documented anywhere?



Some of my guesses:



  • It is old and deprecated thus should not be used anymore

  • It is new and untested.

  • It never got documented properly

  • I just overlooked it many many times in the documentation
