VLANs on Linux

by Carla Schroder

One thing that did not make it into the Linux Networking Cookbook was a chapter on setting up VLANs (Virtual LANs). VLANs are logical subnetting, rather than being constrained by your physical Ethernet switches. Now that "smart" switches have gotten so inexpensive, VLANs are nice options even for small networks. For one example, you can run multiple subnets off a single switch. Parts 1 and 2 of my three-part series are here:

Do More With Less: Build a Linux VLAN
Do More With Less: Port-Based VLANs

Windows and Mac clients can also be members of your VLANs; part 3 will address tagged VLANs, routing and Linux client configuration.

Part 3 runs next week.

Lovely topics on smart-switches/VLANs. Thank you!

Hopefully, you will cover it sometime in this century?
Kind regards

Your google-fu is weak, young Luke :). Though it would be better if I could go back in series like this and add links to later parts. The series went to four parts, so here are the last two:
