Virtual LANs (VLANs)

Virtual LANs (VLANs) allow splitting a single physical LAN into separate Virtual LANs. Each device on a VLAN can only access other devices on the same VLAN and each device is unaware of any other VLAN, which isolates networks from one another, even though they run over the same physical network.

Your TX54 device supports two VLANs modes:

• Trunking: Supports multiple VLANs per Ethernet port, which enables you to extend your VLAN across multiple switches through your entire network.

• Switchport: Each Ethernet port can have one or more VLAN IDs associated to it. Any un-tagged VLAN packets that come into a network interface are automatically tagged with the primary VLAN ID for that switchport. This allows devices on the network that aren’t configured with a VLAN to act as if they are directly connected to the VLAN.
