Introduction

Features

Processor
The 9E423-36 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides a platform for all management functions such as
Spanning Tree, RMON, and MIB support within a scalable RISC-Based
architecture.
Fast Packet Switching
The 9E423-36 incorporates a hardware-based switch design referred to as the
SmartSwitch ASIC, a collection of custom ASICs designed specifically for high
speed switching. Because all frame translation, address lookups, and forwarding
decisions are performed in hardware, the 9E423-36 can obtain a throughput
performance of greater than 750K pps.
Management
The 9E423-36 features SNMP for local and remote management. Local
management is provided through the RS-232 COM ports on the SmartSwitch 9000
Environmental Module using a standard VT-220 terminal or emulator. Remote
management is possible through Cabletron's SPECTRUM or any SNMP-
compliant management tool. Included as management features are the IETF
Standard Management Information Base (MIBs) RMON (RFC1271), IETF MIB II
(RFC-1213), IETF Bridge MIB (RFC-1493), and a host of other Cabletron enterprise
MIBs. The 9E423-36 also offers the user a wide variety of statistical network
management information to enhance network planning and troubleshooting. This
module provides information for each front panel Ethernet 10BASE-T port,
including packet counts along with errored frame information such as collisions,
CRCs, and Giants, via a variety of industry standard and private MIBS. Industry
standard IEEE 802.1d bridging, including Spanning Tree Algorithm, is supported.
Connectivity
The 9E423-36 module has one interface to the INB and three front panel RJ-21
Telco connectors. The INB interface is a fixed connection to INB-2 that allows the
9E423-36 to communicate with other SmartSwitch 9000 modules supporting
various LAN technologies, including Token Ring, FDDI, Ethernet, WAN and
ATM. Each front panel RJ-21 connector provides 12 Ethernet 10BASE-T
connections for UTP and STP links up to 100 meters in length.
Standard Ethernet/Full Duplex Operation
The 9E423-36 Module supports 10BASE-T. The use of 10BASE-T allows each port
on the 9E423-36 Module to be configured, through local and/or remote
management (SNMP), to operate in standard Ethernet mode (simplex) or full
duplex mode. Operating in standard Ethernet mode limits bandwidth to 10 Mbps
per port, while operating in duplex mode doubles bandwidth from 10 Mbps to 20
Mbps per port.
