The 10 Gigabit Ethernet MAC Core is designed to comply with the IEEE802.3ae specification and meets the requirements for both WAN / MAN and LAN connectivity. The version 2 of the core can be used in either NIC (Network Interface Card) or ethernet switching applications. A set of configuration pins is available to dynamically set the core to terminate and form MAC frames (NIC application) or to pass MAC frames without modification to the user application or to the ethernet line (switching application). When used in NIC or switching applications, the core provides support for IEEE managed objects, IETF MIB-II and RMON for management applications (e.g. SNMP).
