Arbitrary vlan interface name – undocumented configuration? – A server stack is the collection of software that forms the operational infrastructure on a given machine. In a computing context, a stack is an ordered pile. A server stack is one type of solution stack — an ordered selection of software that makes it possible to complete a particular task. Like in this post about Arbitrary vlan interface name – undocumented configuration? was one problem in server stack that need for a solution. Below are some tips in manage your linux server when you find problem about linux, linux-networking, vlan, alpine, .
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
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
