It combines all the functions of a high-speed switch function. MIB Autocast encapsulates the on-chip MIB system, including packet buffer, PHY transceivers, media access statistics and sends them out automatically on a predefined controllers, address management, and a nonblocking switch port (or ports) at programmed intervals. This feature is part of fabric into a single 0.13 m CMOS device. It complies with the 8051 micro smart switch option for basicsmart IEEE 802.3, 802.3u, 802.3ab 802.3x specifications, including the managemen via a console port.
