Chapter 1 Introduction; Features - Cabletron Systems MMAC-Plus 9F116-01 User Manual

Introduction
The 9F116-01 MicroLAN™ Module (shown in Figure 1-1) is a two port FDDI
bridge/router used to connect an external FDDI network to one of the two FNB
networks, FNB-1 or FNB-2, on the SmartSwitch 9000 FNB backplane. Another
configuration option allows the module to bridge/route between FNB-1 and
FNB-2 on the FNB backplane. The external FDDI network connects to the 9F116-
01 using a Dual Attached Station (DAS) interface on the module's front panel. The
9F116-01 is ANSI X3T9.5-compliant with two instances of Station Management
(SMT), two instances of MAC, and four instances of PHY and PMD (two per
interface).

Features

Processor
The 9F116-01 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides a platform for all management functions within a
scalable RISC-based architecture.
System Management
The 9F116-01 interfaces to the two System Management Buses (SMB-1 and
SMB-10) for intermodule management. Management features include the
following:
•
•
•
•
Hardware Bridging Logic
Hardware frame filter/forward logic increases the bridging performance of the
9F116-01, allowing the module to achieve higher throughputs (up to 50,000
packets per second).
