Summary:Facilitates supports for the 802.1q standard on virtual networks (VLAN) and one or more levels of independent proprietary virtual networks (OVLAN) without interference between them. It can also support hierarchical structures so that it includes assigning an OVLAN identification tag (3) for each level; the inclusion of external tags (3) transparent to the frames; the inclusion of tags (3) in the non-tagged frames and the comparison of said tags with the list of permitted or prohibited tags from the output interface of the equipment; and the inclusion of a special identification tag which when detected by the equipments makes these transmit the frame directly to allow directional hierarchical structures.
