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.
