ubuntu# apt-get install vlan

2. Create Sub-Interface
# /sbin/vconfig add [interface] [vlan_id]
ex. /sbin/vconfig add eth0 100

3.  on Interface
# ifconfig eth0.100 up
_________________________
การสร้าง sub-interface (vlan tag บน physical interface) บน Linux สามารถทำได้โดยใช้คำสั่ง /sbin/vconfig สำหรับทำให้เครื่องรู้จักกับ vlan ที่ต้องการ

ตัวอย่างการเพิ่ม sub-interface
/sbin/vconfig add eth0 vlan 100
/sbin/ifconfig eth0.100 up

ตัวอย่างการลง sub-interface
/sbin/vconfig rem eth0.100
