RansNet routers support running multiple VLANs on a single physical interface using the IEEE 802.1Q protocol, the industry standard for implementing Virtual LANs (VLANs) on Ethernet networks.
In other words, a single physical interface can be divided into multiple logical interfaces, with each logical interface tagged and assigned to a specific VLAN. Each of these logical VLAN interfaces is referred to as a sub-interface.
CONFIGURATION STEPS
When configuring bridging interfaces, following conditions apply:
Each VLAN interface is a layer 3 logical interface, assign IP address to VLAN interface.
By default physical interface is in VLAN 1
Connected peer (eg. switch port) must be enabled with 802.1q trunking and the configured VLANs must be allowed by the switch trunk port
