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:
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.
