Overview
PMC-Sierra,Inc.
PM3370 Octal 10/100 Mbit/s Switch Port-Controller FEATURES • Monolithic intelligent octal 10/100 Ethernet Switch Port Controller.
• Integrates eight 10/100 MACs that connect to physical layer devices over standard IEEE 802.
3u MIIs.
• Supports the Gigabit EXACT Bus Protocol for device interconnect.
• May be used alone or in combination with other devices to build high density 10/100 switches.
• PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 96 10/100 Mbit/s ports.
• Layer 2 line rate address lookup capability for all Ethernet port configurations supported.
• Store-and-forward switching using output associated input buffering for efficient memory use without Head Of Line (HOL) blocking.
• Supports 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 SmartPath™ Processor supports value-added datapath operations.
• Two 32-bit memory interfaces for flexible combinations of SSRAM, SDRAM, and EPROM allows cost optimization of different applications.
• Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types.
• 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.
• A MAC bypass mode (ENTRE mode) allows a 800 Mbit/s full duplex access channel into the device with 32-bit FIFO bus.
• Allows connection of proprietary ASICs to an EXACT system.
• Supports ATM or Packet over SONET applications.
• Customer product differentiation is enabled by applications using CMI calls to leverage EXACT resources.
VLAN • Up to 4094 IEEE 802.
1Q VLAN tags with support for 4094 FIDs.
• Up to 1022 active VLANs.
• Ingress filtering of packets.
