Introduction
The 9A426-02 ATM Module is a hardware-based switching module that supports
multiple interfaces simultaneously. The module’s interconnecting interfaces
include:
• Up to two front panel ATM interfaces via user-installed ATM Port Interface
Modules (APIMs)
• A fixed interface to the SmartSwitch 9000’s Internal Network Bus (INB)
• A user-configurable interface to the SmartSwitch 9000’s Flexible Network Bus
(FNB-1 or FNB-2)
Each data packet, regardless of the interface in which the packet enters the
module (ATM, FNB, or INB), is initially converted into a common format known
as a canonical frame. Each canonical frame’s header section contains source and
destination information. All canonical frames are forwarded to the module’s
group of SmartSwitch Application Specific Integrated Circuits (ASICs)
collectively known as the SmartSwitch Core.
The SmartSwitch Core can process data in two modes: as a traditional switch or as
a Secure Fast Switch (SFS). When operating as a traditional switch, the Fast Packet
Switch makes filtering/forwarding decisions based on Destination Address, with
standard IEEE 802.1d learning. When operating in SFS mode, all
filtering/forwarding decisions are based on a Destination Address-Source
Address pair, and the associated receive/transmit port.
Canonical frames that enter the 9A426-02 Module via the backplane interface
(FNB or INB) and are destined for the module’s front panel interface(s), are
converted by the module’s ATM Network Interface Block (ANIB) into 53 byte
ATM cells. The ANIB uses a separate set of ASICs to perform hardware-based
packet to cell conversions. This conversion process is an integral part of the
module’s ability to provide high-performance interconnections between legacy
LANs and ATM attached networks.

Introduction
1-2
Conversely, canonical frames destined for the FNB bus on the SmartSwitch 9000
backplane are converted into FDDI packets via the 9A426-02 Module’s FDDI
Network Interface Block (FNIB), and then forwarded onto the FNB.
Canonical frames destined for the INB bus on the SmartSwitch 9000 backplane are
converted into fixed length data packets via the 9A426-02 Module’s INB Network
Interface Block (INB NIB), and then forwarded onto the INB.
Features
Processor
The 9A426-02 Module is equipped with an advanced Intel i960 microprocessor.
This microprocessor provides a platform for all management functions within a
scalable RISC-based architecture.
SmartSwitch Core
The 9A426-02 Module incorporates the SmartSwitch Core, a collection of custom
Application Specific Integrated Circuits (ASICs) designed specifically for high
speed switching. The SmartSwitch ASIC bus is 64 bits wide with a bandwidth of
640 Mbps. Since all frame translation, address lookups, and forwarding decisions
are performed in hardware, the 9A426-02 Module can obtain a throughput
performance of greater than 750K pps.
Management
The 9A426-02 Module has one full implementation of SMT (Version 7.3) and
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, or via telnet. Remote management is
achieved through Cabletron’s SPECTRUM or any SNMP compliant management
tool. Switching statistics of the selected FNB interface include frames filtered,
frames forwarded, and all Spanning Tree Protocol parameters.
Connectivity
The 9A426-02 Module has two front panelATM interfaces. AnATM Port Interface
Module (APIM) can be installed in one (or both) interface(s). The 9A426-02
Module also has one interface to the INB-2 backplane, and one user-configurable
interface to the SmartSwitch 9000 FNB backplane (either FNB-1 or FNB-2, or
neither).
