Announcing 802.1Q VLAN version 1.0.0 for Linux. 802.1Q VLAN is an industry standard that allows you to run multiple Virtual LANs over a single ethernet wire/interface. It also supports priority settings. To user-space code, this VLAN patch makes VLAN devices look like Ethernet devices. The patch is large, so go here to find it: (get version 1.0.0)

Instant Configuration. Previously, Arch Linux used the vconfig command to setup VLANs. This command was superseded by the ip command. Make sure you have iproute2 installed.. In the following examples, let us assume the interface is eth0, the assigned name …

2. Turns out there is no VLAN support in the ifupdown plugin that lets Network Manager work with /etc/network/interfaces, so instead we will have to manually add a keyfile for Network Manager. First generate an UUID for the VLAN interface. root@kayna:~# uuidgen -r 5985c23f-2f9b-4e09-a33e-97505c79c78f.

Linux 802.1q

Example: A Server requires access to two VLANs. The Server’s interface eth0 is connected to a switchport that’s trunk. The original 802.1Q standard defined the 802.1d spanning tree protocol (STP) for bridge topology management. 802.1d is the original IEEE standard that defines a link-management protocol algorithm allowing adjacent bridge devices connected to common Layer 2 segments to discover a loop-free link topology. Howto configure the Linux kernel / net / 8021q Configuration for 802.1Q VLAN support Option: VLAN_8021Q Kernel Versions: 2.6.15.6 (on/off/module) 802.1Q VLAN Support Select this and you will be able to create 802.1Q VLAN interfaces on your ethernet interfaces. 802.1Q VLAN supports almost everything a regular ethernet interface does, including firewalling, bridging, and of course IP traffic 1. Check that the module is loaded by running the command: # lsmod | grep 8021q.

this case all ports of the bridge will have access to all VLANs, which is probably not desired. Use ebtables to pass 802.1Q tagged traffic to VLAN subinterfaces:

802.1q vlan For more on this, see the linux 802.1q VLAN implementation site. Kernels in the late 2.4 series have support for VLAN incorporated into the stock release. The vconfig tool, however needs to be compiled against the kernel source in order to provide userland configurability of the kernel support for VLANs.
