VLAN: Creating a VLAN Interface on OpenBSD

Introduction link

A virtual local area network, commonly called VLAN (for Virtual LAN), is an independent logical computer network. Many VLANs can coexist on the same network switch.

Configuration link

Dynamique link

To create a VLAN interface on the fly:

1

ifconfig vlan110 create

Then assign a tag (VLAN ID) to this VLAN as well as the physical interface on which it should be created:

1

ifconfig vlan110 vlan 110 vlandev sis1

And finally, assign it a specific IP address:

1

ifconfig vlan110 inet 192.168.110.254 netmask 255.255.255.0

Statique link

Now, to keep this configuration active when the machine restarts (/etc/hostname.vlan110):

1

inet 192.168.110.254 255.255.255.0 NONE vlan 110 vlandev sis1
