[LARTC] VLAN patch

[LARTC] VLAN patch

[Michael T. Babcock]

I've just downloaded and started reading through the VLAN patch from
http://sourceforge.net/projects/vlan/ and it seem simple enough to get
working.  I was wondering if anyone else here is running it.

Thanks.

it works fine, and it's integrated in "standard" kernels since 2.4.15
I think. Note that you need a little binary tool to create and delete
vlans (vconfig), and that you may have problems with MTU with some NICs
(check the VLAN page for more information about this MTU problem).

I understand the use of VLANs on a switch, but is it only useful in Linux
when your Linux computer is configured as a bridge?

Where do you get the vconfig tool?

No -- its quite useful for any situation where you might want to communicate
with specific VLANs on a network (or make them).  Feel free to consider having
the IP address of your Samba server on a VLAN address so that the network
traffic isn't 'visible' to other hosts and the workgroup doesn't show up in
everybody's Network Neighbourhood (for a fast example).

This would require (usually) using VLAN capable network cards on the Windows
machines of course.

That should be enough info ... ;-)

What makes such a combination interesting is the added features Linux can 
provide, such as filtering or shaping.

A VLAN enabled bridge alone does not make that much sense as VLANs is usually 
used in conjunction with switches, and switches are essentially fast bridges 
with many ports..

We ran HAL 2001 (www.hal2001.org) with it. Lots of vlans, lots of traffic.
Linux can happily trunk with mega expensive hardware. Works like a charm!

Just be aware of MTU issues - not all drivers or cards can deal with >1500
byte packets.

either from here : http://scry.wanfear.com/~greear/vlan.html
or "apt-get install vconfig" if you run debian.
