Basic VLAN Trunking for Linux.

The first thing you'll want to do is install the VLAN package using aptitude.

aptitude install vlan

Note: if aptitude can't find the package, use the command "aptitude update" before trying to install the package.

Load the 802.1Q module into the kernel

modprobe 8021q

Then verify the module has been loaded into the kernel

lsmod | grep 8021q

The output on your screen should look similar:

Use vconfig to add VLANS

vconfig add "interface" "VLAN"

VLAN's 10, 20, 30, and 40 are now created (as sub-interfaces), labeled as eth0.10, eth0.20, eth0.30, eth0.40

Configure IP Addresses on the VLANS / sub-interfaces.

ifconfig "interface.VLAN" "ip address" netmask "subnet mask"

*Verify the VLANS / sub-interfaces were added and up by running the ifconfig command*

Configure the default gateway (add a route) for each VLAN / sub-interface

route add -net "network address" netmask "subnet mask" gw "default gateway"
