VLANinterface
A VLANInterface is a logical network interface that represents a single virtual local area network (VLAN) on a device. It provides a Layer 3 addressing point for that VLAN, allowing IP-based communication, routing, and network services to be associated with the VLAN. VLAN interfaces are commonly used on routers or Layer 3 switches to enable inter-VLAN routing, and they can also be created on hosts to connect a device to a specific VLAN.
The VLANInterface operates over an 802.1Q tagged trunk. A trunk port carries traffic for multiple VLANs, with
Support and implementation vary by platform. In Linux, VLANInterfaces are implemented as subinterfaces, for example eth0.10
Key considerations include ensuring the trunk allows the VLAN, assigning appropriate IP addresses and gateways, and
