+=== VLAN ===
+VLANs can be configured on top of hardlinks as well as virtual links, like bonding interfaces. They provide a logical network on a physical link.
+In this example we tag two VLANs with Ids 10 and 20 on a physical link <code>enp1s0</code>. The VLAN interfaces become available <code>vlan10</code> and <code>vlan20</code> and can receive additional configuration.
