Introduction

The 9E428-12/36 and 9E429-12/36 (Figure 1-1) are switching modules that provide either 12 or 36 ports, depending on the module. The 9E428-12/36 provide Ethernet ﬁber-optic 10Base-FL connectivity via multimode ST (straight through) connectors, while the 9E429-12/36 modules use single mode ST connectors. There are two ST connectors for each port, one for transmit and one for receive. Each module also provides an additional port that connects directly to the Internal Network Bus (INB) backplane interface. These modules use 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

These modules can operate in two modes: either as a 12/36 port Ethernet traditional switch (using 802.1d standards) with a high speed backbone connection, or as a Secure Fast Switch (SFS) with 12/36 Ethernet connections. Each port 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 work stations.

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 9E428-12/36 and 9E429-12/36 also feature front panel LANVIEW™ Diagnostic LED’s to offer at-a-glance status information about each front panel port, as well as the operation of the overall module.

Introduction

Features

Processor

The 9E428-12/36 and 9E429-12/36 modules are 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 9E428-12/36 and 9E429-12/36 modules incorporate 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, these modules can obtain a throughput performance of greater than 750K pps.

Management

The 9E428-12/36 and 9E429-12/36 feature 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. These modules also offer you a wide variety of statistical network management information to enhance network planning and troubleshooting. The 9E428-12/36 and 9E429-12/36 provide information for each front panel Ethernet 10BASE-FL 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 9E428-12/36 and 9E429-12/36 modules have one interface to the INB and either 12 or 36 front port ST connectors. The INB interface is a ﬁxed connection to INB-B that allows the 9E428 and 9E429 modules to communicate with other SmartSwitch 9000 modules supporting various LAN technologies including: Token Ring, FDDI, Ethernet, WAN and ATM. The 9E428-12/36 multimode ST connectors provide 12 or 36 Ethernet 10BASE-FL connections, with links up to 2000 meters in length, when operating in half duplex. The 9E429-12/36 single mode ST connectors provide 12 or 36 Ethernet 10BASE-FL connections, with links up to 5000 meters in length, when operating in half duplex.

Standard Ethernet/Full Duplex Operation

The 9E428-12/36 and 9E429-12/36 modules support 10BASE-FL. The use of 10BASE-FL allows each port on the modules to be conﬁgured, through local and or remote management (SNMP), to operate in standard Ethernet mode (simplex)

NOTE

Introduction

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 9E428-12/36 and 9E429-12/36 modules provide MIB support including:

• RMON (RFC-1271)

• 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 9E428-12/36 and 9E429-12/36 modules package.

INB

The 9E428-12/36 and 9E429-12/36 modules attach to INB-B of the SmartSwitch 9000 Backplane. The INB Backplane is designed to transport ﬁxed length data blocks between modules in the SmartSwitch 9000 using an INB Time Division Multiplexing (ITDM) design. The SmartSwitch 9000 INB bus delivers 2.0 Gbps of true data bandwidth with all control and management communication being serviced on the 8 bit out-of-band bus. The time slices of the INB manager operates in all three modes at once, without user intervention.

Arbitration for the backplane is accomplished in the INB Time Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensures that no one can get the backplane for more than one time slice at a time.

The ITDM RAM contains 256 4-bit locations. This RAM is used to hold slot numbers of modules participating in INB backplane arbitration. The arbitration engine accesses this RAM once every time slice to get a slot number. That slot number will be granted access on the next time slice if it is requesting. The arbitration engine is always one time slice ahead, meaning that the value read from the RAM is for the next time slice, not the current time slice.

LANVIEW LEDs

The 9E428-12/36 and 9E429-12/36 modules use 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).
