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 EXACT? 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 SmartPath? 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. MANAGEMENT

? System Interface provided in CMI to support standard SNMP software packages, or the porting of existing management software.

? 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.

APPLICATIONS

? Gigabit Ethernet Switches.

? Ethernet Switching Systems Capable of 10, 100, and 1000 Mbit/s Operation When Used with PM3370 and PM3390.

? Gigabit Test Equipment.
