The LAN9303M-AKZE is a 3 port 10/100 managed Ethernet Controller combines all the functions of a 10/100 switch system, including the switch fabric, packet buffers, buffer manager, media access controllers (MACs), PHY transceivers and serial management. It is complies with the IEEE 802.3 (full/half-duplex 10Base-T and 100Base-TX) Ethernet protocol specification and 802.1D/802.1Q network management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications. It is the high performance, high efficiency 3 port Ethernet SWITCH FABRIC. The Switch Fabric contains a 3 port VLAN layer 2 Switch Engine that supports untagged, VLAN tagged and priority tagged frames. The switch fabric provides an extensive feature set which includes spanning tree protocol support, multicast packet filtering and Quality of Service (QoS) packet prioritization by VLAN tag, destination address, port default value or DIFFSERV/TOS.
