Chapter 1
Introduction
The 9F310-02 and 9F315-02 are three port switch modules with two front panel FDDI interfaces and one INB-1 backplane interface. The external FDDI networks are connected to the modules using standard FDDI A/B ports on the front panel. The 9F310-02 uses multi mode fiber, and the 9F315-02 uses single mode fiber optic cables for this connection. The 9F310-02 and 9F315-02 modules employs the Fast Packet Switch (FPS), a high performance switch design, and the Intel i960 micro- processor. The modules can redirect one or both of its front panel FDDI Interfaces to the FNB backplane, creating an INB-1 to FNB bridge/switch product that allows a migration from FNB modules to INB-1 modules.
Features
Processor
The 9F310-02 and 9F315-02 are equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.
Packet Switch Engine
The 9F310-02 and 9F315-02 module incorporates the Fast Packet Switch (FPS), a collection of custom ASlCs designed specifically for high speed switching. The FPS bus is 64 bits wide with a bandwidth of 320 Mbps. Since all frame translation, address lookups, and forwarding decisions are performed in hardware, the
9F310-02 and 9F315-02 can obtain a throughput performance of greater than 150K pps.
Management
The 9F310-02 and 9F315-02 modules have two full implementations of SMT (Version 7.3), one per interface, and SNMP for local and remote management. Local management is provided through the RS-232 Com ports on the MMAC-Plus Environmental Module using a standard VT-220 terminal or emulator. Remote management is possible through Cabletron’s SPECTRUM or any SNMP compliant management tool as well as telneting to the module. Management features including module insert/bypass control, MAC placement, front panel/FNB configuration, and SMT statistics. Bridging statistics on both FDDI
