Techniques are described for dynamically building an Ethernet virtual local area network (VLAN) interface in a network device. The techniques allow dynamic building of a second VLAN interface over a first VLAN interface statically built over an Ethernet port configured to support dynamic VLANs in a network device. A network device may receive a plurality of Ethernet packets from subscriber devices and dynamically build a second VLAN interface over the first VLAN interface for each of the subscribers. Once the second VLAN interface is built, the network device dynamically builds interface columns over the second VLAN interface for each protocol associated with the Ethernet packets. The network device may then authenticate a user associated with the plurality of Ethernet packets. Once the user has logged out of the network device, the network device may tear down the interface columns while persistently maintaining the corresponding second VLAN interface.
