Does the VX-1000HDx support VLANs?

Yes. The VX-1000HDx supports VLANs. Each port can have multiple VLANs enabled. Each VPI/VCI on a single port will allow 1 VLAN ID. If port 1 needs 2 VLAN ID’s, you can create one VLAN ID on 0/35 and another VLAN ID on 0/32. Multiple VLAN packets sent through the port will depend on the modem. Most modems will allow only 1 VLAN to work.
