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
