2001 14:09:52 -0700 This patch adds 802.1Q VLAN support to the linux kernel. AARP / +#define ETH_P_8021Q 0x8100 / 802.1Q VLAN Extended Header

IEEE 802.1Q Encapsulation In order to correctly deliver the traffic on a trunk port with several VLANs, the device uses the IEEE 802.1Q encapsulation or tagging method. Ubuntu configuration of an interface for multiple VLAN tagging. Example: A Server requires access to two VLANs. The Server’s interface eth0 is connected to a switchport that’s trunk.

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) Reading 802.1Q frames with specific VLAN tag under Linux. Ask Question Asked 6 years, 11 months ago. Active 4 years, IEEE 802.1Q is an open standard, which means, theoretically, that all compatible devices can interoperate regardless of manufacturer. Linux VLANs are based on 802.1Q, and almost any switch that advertises “VLAN” will support this standard. 802.1q provides for an additional 4-bytes of information added to the L2 frame, 12 bits of which indicate the VLAN is.

Linux 802.1q

You may skip the line above if your kernel was compiled with 802.1q and not as module. In Red Hat Enterprise Linux 7, the 8021q module is loaded by default. If necessary, you can make sure that the module is loaded by issuing the following command as root: ~]# modprobe --first-time 8021q modprobe: ERROR: could not insert '8021q': Module already in kernel. Linux has the ability to use an Ethernet interface as an 802.1Q trunk port, allowing it to concurrently send and receive traffic on multiple VLANs. This is provided by the 8021q kernel module, which can be configured non-persistently using the ip link command: An 802.1Q VLAN tagging interface can be created on top of bridge, bond, and team interfaces, however there are some things to note: In the case of VLANs over bonds, it is important that the bond has slaves and that they are “ up ” before opening the VLAN interface.

To receive packets with a specific VLAN, I created a VLAN interface and bound my raw socket to it. Now I can just send 802.3 frames, VLAN Bridging (802.1q).

I'm not quite sure how to set it up, but hopefully this will lead you in the right direction.

This is provided by the 8021q kernel module, which can be configured non-persistently using the ip link command: 802.1Q VLAN supports almost everything a regular ethernet interface does, including firewalling, bridging, and of course IP traffic. You will need the 'vconfig' tool from the … IEEE 802.1Q is an open standard, which means, theoretically, that all compatible devices can interoperate regardless of manufacturer.

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.

The Overflow Blog Using 802.1q VLANs on Linux. The vlan tools (user mode utilities) should already be present on the Linux host (vconfig). On GNU/Debian they may be installed with “apt-get install vlan”. Setting up the VLAN interfaces (as root): # modprobe 8021q. You may skip the line above if your kernel was compiled with 802.1q and not as module. In Red Hat Enterprise Linux 7, the 8021q module is loaded by default. If necessary, you can make sure that the module is loaded by issuing the following command as root: ~]# modprobe --first-time 8021q modprobe: ERROR: could not insert '8021q': Module already in kernel.

Vlan-devices are virtual ethernet devices which represents the virtual lans on the physical lan. 2008-07-30 Need to set up a 802.1q VLAN on SUSE Linux Enterprise Server so that outgoing packets are tagged with the proper VLAN id. Resolution. SUSE Linux has great support for VLANs built in by default. For details on setting up VLANs in SUSE Linux, see the documentation for the vlan package.
