A method for processing data may include receiving packetized data via at least one of a plurality of input ports in an Ethernet switch. Each of the plurality of input ports may be partitioned into a plurality of virtual local area network (VLAN) port domains with an assigned port domain identification (ID) for processing 802.1 Class of Service (CoS) priority and Quality of Service (QoS) packetized data. The Ethernet switch may be integrated within a single gigabit Ethernet IP telephone chip, the received packetized data having assigned at least one priority class. One or more bits in at least one of a plurality of registers in the Ethernet switch may be used to filter at least one ingress frame in the packetized data, based on at least one packet header attribute of the at least one ingress frame.
