9–Linux Configuration for Bonding Mode and Virtual LAN (VLAN) Configuring Virtual LAN (VLAN) Under Linux

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

The vconfig add command creates a VLAN device on eth0 and will, in turn, create an eth0.5 interface.

2.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
