ABSTRACT:
An Ethernet data packet including a VLAN tag header and a VLAN identification field is modified. The modification is accomplished by inserting in place of the VLAN tag header a field of the same size including selected information. The VLAN identification may be retained. The inserted field may include a first field indicating the presence of the VLAN identification field and a second field of selected information, the second field being longer than the first field.
