| PMC-Sierra,Inc. PM3380 * Hardware statistics collection supports RMON-I (nine groups), Ethernet MIB, and SNMP agent functions. * All statistics registers and data structures accessible through the CMI. * Supports the implementation of Spanning Tree (IEEE 802.1D) by exchanging BPDU packets on all ports. Gigabit Ethernet Switch Port Controller FEATURES * Monolithic intelligent Gigabit Ethernet Switch Port Controller. * Integrates an IEEE 802.3z-compatible Gigabit MAC. * May be used alone or in combination with other devices to build 10/100 or Gigabit switches. * Supports the Gigabit EXACTTM Bus Protocol for device interconnect. * May be used alone or in combination with other device to build high density Gigabit switches. * PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 16 Gigabit ports. * Layer 2 line rate address lookup capability for all Ethernet port configurations supported. * Store-and-forward switching using output association input buffering for efficient memory use without Head Of Line (HOL) blocking. * Supports up to 8,000 MAC addresses. * 1022 multicast groups available. Bitmask per group defines membership. * EXACT Bus is compatible with common serial devices for simple system stacking using coax or twinax cable. * Support for IEEE 802.1D bridging and spanning tree algorithm in an external processor. * Embedded SmartPathTM Processor supports value-added datapath operations. * Two 32-bit memory interfaces for flexible combinations of SSRAM and EPROM allow cost optimization of different applications. * Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types. Gigabit Ethernet Interface Transmit Control Gigabit Media Access Control Address Resolution Logic Egress Queue Manager SmartPath CPU EXACT Bus Input Port Receive Control Micro Interface Memory Port Controller Memory Port Controller Ingress DMA Unit Ingress Queue Manager EXACT Ring Interface EXACT Bus Output Port VALUE ADD * Control and Management Interface provides standard interface for non real-time access to data structures (such as SNMP and RMON applications). * Customer product differentiation is enabled by applications using CMI calls to leverage EXACT system resources. VLAN * Up to 4094 IEEE 802.1Q VLAN tags with support for 4094 FIDs. * Up to 1022 active VLANs. * Ingress filtering of packets. * Shared and independent learning. * GARP, GVRP, GMRP packet identification and forwarding to external CPU for processing. * Tag insertion and removal for unicast and multicast packets. COMPATIBILITY * Interworks with the PM3370 Octal 10/100 Switch Port Controller. * Interworks with the PM3390 Eight Port EXACT Bus Switch Matrix. PACKAGING * Provides a standard five signal P1149.1 JTAG test port for boundary scan board test purposes. * Implemented in low power 3.3 V, CMOS technology with 5 V tolerant MII interface. * Available in a 352-pin Ball Grid Array (BGA) package. PRIORITY * Class of service supported via IEEE 802.1D (formerly 802.1p) with two levels of priority. BLOCK DIAGRAM System Clock EXACT Bus Reference Clock Microprocessor Interface MANAGEMENT * System Interface provided in CMI to support standard SNMP software packages, or the porting of existing management software.
