## VLAN

## ====

|
##
|

|
|
## Virtual LANs give you the ability to sub-divide a LAN. Linux can
|
||
|
|
## accept VLAN tagged traffic and presents each VLAN ID as a
|
||
|
|
## different network interface (eg: eth0.100 for VLAN ID 100)
|
||
|
|
##
|
||
|
|
## Some Liminix devices with multiple ethernet ports are implemented
|
||
|
|
## using a network switch connecting the physical ports to the CPU,
|
||
|
|
## and require using VLAN in order to send different traffic to
|
||
|
|
## different ports (e.g. LAN vs WAN)
