Configuring Virtual LAN (VLAN) Under Linux
To configure the VLAN function:
1. Type the following command to see if the 8021q.ko driver has been
loaded:
% lsmod | grep 8021q
Type the following command if the driver has not been loaded:
% modprobe -v 8021q
2. The vconfig add command creates a VLAN device on eth0 and will, in
turn, create an eth0.5 interface. Type the following command for eth0 to
add VLAN ID 5:
% vconfig add eth0 5
3. Type the ifconfig command to assign an IP address to the VLAN
interface:
% ifconfig eth0.5 192.168.1.100 netmask 255.255.255.0
broadcast 192.168.1.255 up
4. Type the following command to get detailed information about the VLAN
interface:
% cat /proc/net/vlan/eth0.5
Repeat Steps 2 and 3 if more than one VLAN is required.
Type the following commands to delete a VLAN interface:
% ifconfig eth0.5 down
% vconfig rem eth0.5
