Introduction

The 9A426-02 ATM Module is a hardware-based switching module that supports
multiple interfaces simultaneously. The module’s interconnecting interfaces
include:

Chapter 1

• 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.

1-1

Introduction

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 thr ough
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 panel ATM interfaces. An ATM 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).

1-2

Management Information Base (MIB) Support

Preparing and Installing the 9A426-02 Module

The Reset Switch

The Reset switch is located under the top plastic tab as shown in Figure 2-12. Use
the reset switch to reset the module’s processor, shutdown (power down) the
module, and/or restart the module.

• To reset the module’s i960 processor, press the reset switch twice within three
seconds.

• To shutdown the module, press and hold the reset switch for three or more
seconds.

• To restart the module, press the reset switch momentarily.

To enhance module security, use SNMP management to disable the reset switch.

Operation

The 9A426-02 Module has three fixed network interface connections: the
module’s two front panel ATM ports, and the module’s INB interface each
connect to the module’s SmartSwitch ASIC core.

Chapter 3

In addition to fixed interface connections, the module offers a user-configurable
FNB interface. Through Local Management or SNMP, you can connect the
module’s SmartSwitch ASIC core to one (or none) of the two FNB interfaces (FNB­1 or FNB-2). Keep in mind that connecting the module’s SmartSwitch ASIC core
to an FNB interface also connects the selected FNB to the module’s three fixed
interface connections (the two front panel ATM ports and the INB interface).

As shown in Figure 3-1, packets can be received simultaneously at the front panel
ATM ports, the INB interface and, if configured by the user, one of the FNB
interfaces (FNB-1 or FNB-2). All packets that enter the module are converted into
a common format known as a canonical frame. The SmartSwitch ASIC core’s
circuitry determines the ports to which the frames are forwarded.

LAN Emulation

The 9A426-02 Module interconnects LANs over an ATM network through a
method known as LAN Emulation. LAN Emulation, or LANE, is a
method that makes a connection-orientated ATM network look and behave like a
shared connectionless Ethernet or Token Ring LAN Segment. Unlike other
methods of interconnecting LANs over ATM, LANE can handle routable
protocols such as TCP/IP, IPX and DECnet, as well as non-routable protocols
such as NetBlOS and SNA.

LANE is an ATM Forum standard that is implemented by a variety of vendors
and ensures the interoperability between vendors to allow connectivity from
legacy LANs over an ATM backbone.

While LANE allows users to utilize ATM as a backbone between legacy LANs, it
also allows legacy LAN users to communicate with native ATM devices such as
file servers.

LANE allows you to retain equipment that is currently installed on your desktop,
while providing the capability of a high-speed uplink to an ATM network. As
such, it enhances your current equipment, as well as the equipment’s operating
system software. LANE provides high-speed ATM performance, without a
wholesale swap of hardware.

Operation

System Management Buses

There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide out-of-band management and
intermodule management communication.

SMB-1 Bus

The SMB-1 is a 1Mbs management bus located within the SmartSwitch 9000. This
bus is utilized by all diagnostic controllers in the system including connectivity
modules, power supply modules and the environmental module. The SMB-1
transports inter-chassis information between system components, such as power
and environmental information, as well as diagnostic messages. Periodic loop­back tests are performed by all modules which share this bus to ensure the
validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be
used as an alternate communication channel.

3-3

Operation

SMB-10 Bus

The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000
which is also used for inter-chassis communication of modules as well as serving
as an out-of-band management channel into the SmartSwitch 9000. The SMB-10 is
externalized from the chassis via an optional Ethernet Port Interface Module
(EPIM) located on the front of the Environmental Module. Through an EPIM
connection, full SNMP management of the SmartSwitch 9000 is available out-of­band from user data. Modules which share the SMB-10 bus periodically send out
loop-back packets to ensure the validity of SMB-10. In the event a fault is detected
on the SMB-10, the SMB-1 can be used as an alternate communication channel by
the modules.

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its
supporting logic. The diagnostic controller is designed to control the power-up
sequencing of modules, monitor the 9A426-02 Module input and output power
parameters, keep watch over the main host processor, as well as monitor the
temperature and control the SMB LANVIEW diagnostic LED. Although the
diagnostic controller and the main host processor can operate independent of
each other if needed, they exchange information about each other’s status and
overall module condition. The information gathered by the diagnostic controller
is available to the network manager via local/remote management and the LCD
located on the environment module. The 9A426-02 Module has been designed so
that in the event of a diagnostic controller fault, the 9A426-02 Module will
continue to function.

DC/DC Converter

The DC/DC converter converts the 48 VDC on the system power bus to the
necessary operating voltages for its host network services module. The diagnostic
controller monitors and controls the operation of the DC/DC converter.

INB Network Interface Block

The 9A426-02 Module’s INB interface includes a Network Interface Block
(INB NIB). Canonical frames processed by the module’s SmartSwitch ASIC core
that are destined for the INB on the SmartSwitch 9000’s backplane are converted
by the INB NIB into fixed length data blocks and then transmitted on the INB.
Conversely, data blocks received by the module from the INB are converted by
the INB NIB into canonical frames and forwarded to the SmartSwitch ASIC core
for processing.

3-4

FDDI Network Interface Block

The 9A426-02 Module’s FNB Interface includes an FDDI Network Interface Block
(FNIB). Canonical frames processed by the module’s SmartSwitch ASIC core that
are destined for one of the two FNBs on the SmartSwitch 9000’s backplane are
first converted by the FNIB into FDDI packets and then transmitted onto the
selected FNB. Conversely, FDDI packets received by the module from an FNB are
converted by the FNIB into canonical frames and forwarded to the SmartSwitch
ASIC core for processing.

ATM Network Interface Block

The 9A426-02 Module’s ATM Interface includes an ATM Network Interface Block
(ANIB). ATM cells that enter the module’s front panel port(s) are converted by the
module’s ANIB into canonical frames. The ANIB uses hardware (ASICs) to
perform its conversions. The canonical frames are then forwarded to the
SmartSwitch ASIC core (a separate set of ASICs on the module) for processing.
Conversely, canonical frames processed by the module’s SmartSwitch ASIC core
that are destined for front panel ATM ports are converted via ASICs in the ANIB
into fixed length (53 byte) ATM cells and then transmitted to the ports. The ANIB
uses encapsulation techniques in accordance with the ATM Forum LAN
Emulation Specification. These techniques include the capability to encapsulate
ATM data in either Ethernet or Token Ring frame formats.

Operation

SecureFast Virtual Networking

Secure Fast Virtual Networking combines the best elements of bridging and
routing technologies with connection-oriented switching. Essential to Cabletron's
SecureFast architecture is the ability to embed layer-three virtual routing services
directly into its high-performance switches. Through a simple firmware upgrade,
customers can add "intranet management" software to a broad line of Cabletron
switches, including an installed base of over one million ports.

With Cabletron's "connection-oriented" architecture, users avoid latency and
performance problems and can build intranetworks that more closely mirror the
organizational structure of their business.

Since SecureFast Virtual Networking implements the same connection-oriented
concepts as ATM, customers are guaranteed a smooth migration from packet­based LANs to cell-based technologies. SecureFast Switching allows customers to
receive many of the benefits of ATM such as security and accountability within
LAN infrastructures.

3-5

Operation

An equally important SecureFast Virtual Networking feature is a broadcast
interception service which resolves issues such as security, broadcasts, multi-casts
and network flooding. Broadcast interception allows customers to cost-effectively
control broadcast traffic in a switched network without requiring a router.

i960 Core

The i960 core provides the SNMP protocol stacks, to support industry standard
MIBs. Additionally, Cabletron enterprise extension MIBs are supported for each
media type. Advanced management services, such as the Distributed LAN
Monitor , telnet and network addr ess to MAC address mapping, ar e also pr ovided
by the i960 core.

The host engine sends and receives packets via the CPU SmartSwitch ASIC
Interface. This method allows the traditional switch to perform spanning tree
protocol and other traditional switching functions. The SMB Interfaces provide
communication to the Host Engine for management functions and
communication with other modules in the chassis.
