Preparations
Install user mode programs to enable VLANs on your ethernet devices:
$ sudo apt-get install vlan
Load 8021q module (IEEE 802.1Q):
$ sudo modprobe 8021q
To load 8021q module at the boot time add it to the /etc/modules file:
$ sudo echo 8021q >> /etc/modules
$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with “#” are ignored.
# Parameters can be specified after the module name.

Solution For Temporary
Create VLAN 700 on the eth0 device:
$ sudo vconfig add eth0 700
Add VLAN with VID == 700 to IF -:eth0:-
Set IP address (10.100.10.77 netmask 255.255.255.0 in this example):
$ sudo ifconfig eth0.700 10.100.10.77/24
Created interface is named as eth0.700:
$ sudo ifconfig -a
eth0 Link encap:Ethernet HWaddr 84:8f:69:b0:fa:0a
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:49
eth0.700 Link encap:Ethernet HWaddr 84:8f:69:b0:fa:0a
inet addr:10.100.10.77 Bcast:10.100.10.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:11 errors:0 dropped:0 overruns:0 frame:0
TX packets:53 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:884 (884.0 B) TX bytes:3158 (3.0 KiB)
Now you can access other hosts available in VLAN 700:
$ ping -c 1 10.100.10.1
PING 10.100.10.1 (10.100.10.1) 56(84) bytes of data.
64 bytes from 10.100.10.1: icmp_req=1 ttl=64 time=1.28 ms
— 10.100.10.1 ping statistics —
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.282/1.282/1.282/0.000 ms
To remove VLAN 700 from the eth0 interface execute command:
$ sudo vconfig rem eth0.700
Removed VLAN -:eth0.700:-
Permanent solution
To create VLAN at the boot time you need to get familiar with /etc/network/interfaces configuration file (man interfaces, man vlan-interfaces).
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
To create VLAN 700 on the eth0 interface at the boot time just add similar configuration:
# add vlan 700 on eth0 – static IP address
auto eth0.700
iface eth0.700 inet static
address 10.100.10.77
netmask 255.255.255.0
