Introduction
The 9E423-36 (Figure 1-1) is a 36-port switching module. Three RJ-21 Telco
connectors support 36 10BASE-T ports with a port connecting to the Internal
Network Bus (INB) backplane interface. This module uses a SmartSwitch ASIC
design and an advanced Intel i960
a platform for all management functions within a scalable RISC-Based
architecture.

®
microprocessor. This microprocessor provides
The module can operate in two modes: as a 36-port Ethernet traditional switch
(using 802.1d standards) with a high speed backbone connection or as a Secure
Fast Switch (SFS) with 36 Ethernet connections. Each port of the 9E423-36 can be
configured to operate in the Full Duplex mode. This configuration allows each
port to provide a full 20 Mbps of bandwidth for file servers or high end user
intensive workstations.
Network management information is available through a variety of methods. All
information based on Simple Network Management Protocol (SNMP) is
accessible either via an in-band (Front Panel port), Side Band (SMB-10), or via the
Environmental Module’s COM ports. Serial Line Internet Protocol (SLIP) or
Point-to-Point Protocol (PPP) is supported by the Environmental Module’s COM
ports. For more information on the SMB-10, SLIP or PPP, refer to the SmartSwitch
9000 Local Management User’s Guide.
The 9E423-36 also features front panel LANVIEW™ Diagnostic LEDs to offer at-a-
glance status information about each front panel port, as well as the operation of
the overall module.
Ethernet networks are connected to the 9E423-36 module through three standard
RJ-21 Telco connectors built in the front of the module. Each connector provides
12 Ethernet 10BASE-T connections for UTP and STP links up to 100 meters long.

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 SNMPcompliant 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.
1-2
Page 11
NOTE
chaptitle
Management Information Base (MIB) Support
The 9E423-36 provides MIB support including:
• RMON (RFC-1757)
• IETF MIB II (RFC-1213)
• IETF Bridge MIB (RFC-1493)
and a host of other Cabletron Enterprise MIBs.
For a complete list of supported MIBs, refer to the release notes provided in the
9E423-36 package.
INB
The 9E423-36 attaches to INB2 of the SmartSwitch 9000 Backplane. The INB has a
capacity of 2.5 Gbps to interconnect SmartSwitch 9000 modules supporting
Ethernet, FDDI, Token Ring, WAN and ATM networks. The INB transports fixed
length data blocks between modules in the SmartSwitch 9000 hub using a Time
Division Multiplexing (TDM) design. Within the INB there is a 64-bit wide data
bus and an eight-bit control management bus. Each module that attaches to the
INB has an INB Network Interface Block (NIB). The INB NIB converts canonical
frames to fixed length data blocks for transmission onto the INB. For data blocks
received from the INB, the INB NIB reassembles the data blocks received from the
INB back into canonical frames for transmission to the SmartSwitch ASIC and
ultimately to the front panel port. The INB can time slice its bandwidth using one
of three methods:
• The default method is standard TDM round-robin bandwidth arbitration.
• The second method is for modules to reserve a specific amount of bandwidth
using MONARCH, Cabletron’s INB Bandwidth Arbitrator.
• The third method permits the lowest slot number to use any bandwidth not
used by the previous two methods.
LANVIEW LEDs
The 9E423-36 uses LANVIEW – the Cabletron Systems built-in visual diagnostic
and status monitoring system. With LANVIEW LEDs, you can quickly identify, at
a glance, system status as well as the device, port, and physical layer status. Two
LEDs indicate the transmission and reception of data from the INB SmartSwitch
9000 backplane connection. Each of the 12 Ethernet front panel ports features two
LEDs per port to indicate the port’s Administrative status (enabled/disabled),
LINK status (Link/Nolink), and Data Activity (receiving and transmitting data).

Operation
The 9E423-36 module is a 37-port device. Three front panel RJ-21 Telco connectors
support 36 10BASE-T ports, each port being a separate collision domain with the
37th port connecting to INB-2.
As shown in Table 3-1, Ethernet Network Interface Blocks (ENIBs) convert data
packets received from any of the 10BASE-T ports into a canonical frame format
before forwarding to the SmartSwitch ASIC, while the Internal Network Bus
Network Interface Block (INB NIB) converts data packets received from the INB
into a canonical format before forwarding to the SmartSwitch ASIC.

Operation
ENIB
All data packets destined for a front panel port, the INB, or the i960 are converted
into the canonical format before forwarding to the SmartSwitch ASIC. Network
Interface Blocks (NIBS) check for valid data packets entering the system. If an
errored data packet is found, the SmartSwitch ASIC flags the error and does not
forward the errored data packet to any outbound ports. Once in this common
format, the SmartSwitch ASIC decides (from header information) the port
destination of data packets. Data packets are then converted from the canonical
format to the proper format for the interface destination, whether it is a front
panel port or connection to the INB.
The Ethernet Network Interface Block (ENIB) converts Ethernet data packets
received through front panel ports into a common canonical format that allows
the SmartSwitch ASIC Engine to determine the proper destination port. The ENIB
also converts data packets from the common canonical format back to Ethernet
data packets for transmission out front panel ports.
SmartSwitch ASIC
The SmartSwitch ASIC is a hardware-based switch design that is the key building
block of the SmartSwitch 9000 hub. The SmartSwitch ASIC makes all filtering/
forwarding decisions in custom hardware, as opposed to software like in
traditional bridges. This custom hardware enables the SmartSwitch ASIC to
process over 750K frames per second. The SmartSwitch ASIC is designed to
support up to 64 ports, shared between the host processor, the INB backplane,
and LAN/WAN interfaces on the front panel of SmartSwitch 9000 modules. The
SmartSwitch ASIC can operate in two modes:
• Traditional Switch - When operating as a traditional switch, the SmartSwitch
ASIC makes filtering/ forwarding decisions based on Destination Address
(DA), with standard IEEE 802.1d learning.
• SecureFast Switch (SFS) - When operating as a SecureFast Switch switch, all
filtering/forwarding decisions are made based on a Destination AddressSource Address (DA-SA) pair and the associated receive/transmit port to
deliver virtual circuit capabilities using traditional packet technologies
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 address to MAC address mapping, are also provided
by the i960 core.
3-2
Page 25
The Host engine sends and receives packets via the CPU’s SmartSwitch ASIC
Interface. This allows the bridge to perform spanning tree protocol and other
bridging functions. The SMB Interfaces provide communication to the Host
Engine for management functions.
INB NIB
Each module that attaches to the Internal Network Bus (INB) has an INB Network
Interface Block (NIB). The INB NIB converts canonical frames to fixed length data
blocks for transmission onto the INB. For data blocks received from the INB, the
INB NIB reassembles the data blocks back into canonical frames for transmission
to the SmartSwitch ASIC.
Operation
System Management Buses
There are two management channels within the SmartSwitch 9000 system: the
SMB-1 and the SMB-10. These buses provide side-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
loop-back tests are performed by all modules that 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.
SMB-10 Bus
The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000.
This bus is used for inter-chassis communication of modules as well as serving as
an side-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 side-band from user data. Modules that share the SMB-10 bus
periodically send out loop-back packets to ensure the validity of SMB-10. If a fault
is detected on the SMB-10, the SMB-1 can be used as an alternate communication
channel by the modules.
3-3
Page 26
Operation
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 9E423-36 input and output power
parameters, keep watch over the main host processor, monitor the temperature,
and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic
controller and the main host processor can operate independently of each other if
needed, they exchange information about each others 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 9E423-36 is designed to continue functioning in the
event of a diagnostic controller fault.
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 Interface
The INB Backplane is designed to transport fixed length data blocks between
modules in the SmartSwitch 9000 using a Time Division Multiplexing (TDM)
design. The SmartSwitch 9000 INB bus delivers 2.5 Gbps of true data bandwidth
with all control and management communication being serviced on the 8-bit outof-band bus. The INB can time slice its bandwidth using one of three methods:
• The default method is standard TDM round-robin bandwidth arbitration.
• The second method is for modules to reserve a specific amount of bandwidth
using MONARCH, Cabletron’s INB Bandwidth Arbitrator.
• The third method permits the lowest slot number to use any bandwidth not
used by the previous two methods.
