It Even though this device is primarily targeted for the cost-sensitive combines all the functions of a high-speed switch systemincluding unmanaged market, very low-cost management can also be provided packet buffer, PHY transceivers, media access controllers, address utilizing the proprietary MIB Autocast function. MIB Autocast management, and a non-blocking switch fabricinto a single 0.18 encapsulates the on-chip MIB statistics and sends them out automatically CMOS device. It complies with the IEEE 802.3, 802.3, and 802.3x on a predefined port (or ports) at programmed intervals. This feature specifications, including the MAC control PAUSE frame and auto- eliminates the need for a costly CPU and simplifies the management negotiation subsections, providing compatibility with all industry-standard interface. Ethernet and Fast Ethernet devices. Using this mode, the BCM5325M periodically transmits a legal Ethernet This device contains five full-duplex 10BASE-T/100BASE-TX Fast frame on a designated port. The frames can be intercepted by an external Ethernet transceivers, each of which performs all of the physical layer management probe or a dedicated network management application, interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 resident on any node within the network. This function requires only a Unshielded Twisted Pair (UTP) cable and 100BASE-TX Fast Ethernet on small, low-cost microcontroller to initialize and configure the device. Category 5 UTP cable. The BCM5325M provides an on-chip MIB statistics register to collect, SPI or E2PROM interfaces provide easy programming of the 802.1p QoS receive, and transmit statistics for each port. Additionally it provides direct queues. This allows switch traffic to be given different classes of priority or hardware support for the EtherLike MIB, Bridge MIB, MIB II (interfaces) service, for example, voice traffic for IP phone applications, video traffic for and the first four groups of the RMON MIB. All nine groups of RMON can multimedia applications, or data traffic for e-mail applications. be supported by using additional capabilities, such as port mirroring/ snooping, together with an external microcontroller to process some MIB attributes. The MIB registers can be accessed through the serial management port by an external microcontroller.
