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.

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).
