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

Introduction  
interfaces provide frames filtered, frames forwarded, and all Spanning Tree  
Protocol parameters. The 9F310-02 and 9F315-02 modules support the IETF FDDI  
MIB (RFC-1512), IETF MIB ll (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a  
host of Cabletron enterprise MIBs. In addition, the front panel provides LEDs for  
FDDI link status per port as well as transmit and receive activity.  
Connectivity  
The 9F310-02 and 9F315-02 modules have one interface to the INB-1, two front  
panel FDDI interfaces, or two FNB interfaces to the MMAC-Plus FNB backplane.  
The front panel A/B port connections are via standard fiber FDDI MIC  
connectors. The INB-1 interface is fixed, however, and the two FDDI interfaces  
can attach to one or both of the front panel connectors, one or both of the FNB  
interfaces (FDDI-1 or FDDI-2), or one of each.  
Management Information Base (MIB) Support  
Both 9F310-02 and 9F315-02 provide MIB support including:  
IETF FDDI MIB  
IETF MIB II  
IETF Bridge MIB  
a host of Cabletron Enterprise MIBs.  
NOTE  
For a complete list of supported MIBs, refer to the release notes provided in  
the 9F310-02 and 9F315-02 package.  
LANVIEW LEDs  
The 9F310-02 and 9F315-02 use LANVIEW – the Cabletron Systems built-in visual  
diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly  
identify the device, port, and physical layer status at a glance.

Operation  
The 9F310-02 and 9F315-02 modules are capable of bridging/switching any three,  
of five possible interfaces, depending on how it is configured. The INB-1  
connection is always fixed. When configuring the module, the decision is made to  
connect both front panel ports, both FNB ports, or one front panel and one FNB  
port to the bridge.  
As shown in Figure 3-1, packets may be received at the front panel FDDI ports,  
the FNB rings (FNB-1 and/or FNB-2), and/or the INB-1 bus, according to the user  
configuration. These packets are converted into canonical format. The Fast Packet  
Switching circuitry decides from header information where the packets should be  
sent. They are then converted from canonial format to the proper format for that  
interface.

Operation  
System Management Buses  
There are two management channels within the MMAC-Plus system: the SMB-1  
and the SMB-10. These buses provide out-of-band management and inter-module  
management communication.  
SMB-1 Bus  
The SMB-1 is a 1Mbs management bus located within the MMAC-Plus. This bus  
is utilized by all diagnostic controllers in the system including connectivity  
modules, power supply modules and the environmental module. The SMB-1  
transports inter-chassis information between system components, such as power  
and environmental information, as well as diagnostic messages. Periodic  
loop-back test are preformed by all modules which share this bus to ensure the  
validity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may be  
used as an alternate communication channel.  
SMB-10 Bus  
The SMB-10 is a 10Mbs management bus located within the MMAC-Plus which is  
also used for inter-chassis communication of modules as well as serving as an  
out-of-band management channel into the MMAC-Plus. The SMB-10 is  
externalized from the chassis via an optional Ethernet Port Interface Module  
(EPIM) located on the front of the Environmental Module. Through an EPIM  
connection, full SNMP management of the MMAC-Plus is available out-of-band  
from user data. Modules which share the SMB-10 bus periodically send out loop-  
back packets to ensure the validity of SMB-10. In the event a fault is detected on  
the SMB-10, the SMB-1 can be used as an alternate communication channel by the  
modules.  
System Diagnostic Controller  
This diagnostic controller is composed of a Z-80 microprocessor and it’s  
supporting logic. The diagnostic controller is designed to control the power-up  
sequencing of modules, monitor the 9F310-02 and 9F315-02 input and output  
power parameters, keep watch over the main host processor, as well as monitor  
the temperature and control the SMB LANVIEW diagnostic LED. Although the  
diagnostic controller and the main host processor can operate independent of  
each other if needed, they exchange information about each others status and  
overall module condition. The information gathered by the diagnostic controller  
is available to the network manager via local/remote management and the LCD  
located on the environment module. The 9F310-02 and 9F315-02 have been  
designed so that in the event of a diagnostic controller fault, the 9F310-02 and  
9F315-02 will continue to function.  
3-2  
 
DC/DC Converter  
DC/DC Converter  
The DC/DC converter converts the 48 VDC on the system power bus to the  
necessary operating voltages for its host network services module. The diagnostic  
controller monitors and controls the operation of the DC/DC converter.  
INB Interface  
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 Fast Packet Switch (FPS) then from the FPS to the front panel  
ports.  
Fast Packet Switch  
The Fast Packet Switch (FPS) is a hardware based switch design that is the key  
building block of the MMAC-Plus. All filtering/forwarding decisions are made in  
hardware as opposed to software as in traditional bridges. This custom hardware  
allows the FPS to process over 150K frames per second. The FPS is designed to  
support up to 64 ports that are shared between the host processor, the INB  
backplane, and LAN/WAN interfaces on the front panel of MMAC-Plus  
modules. The FPS can operate in two modes; as a traditional bridge or as a  
SecureFast Packet Switch (SFPS). When operating in bridge mode, it makes  
filtering /forwarding decisions based on Destination Address (DA), with  
standard IEEE 802.1d learning. When operating in SFPS mode, all  
filtering/forwarding decisions are made based on a DA-SA pair and its receive  
port. These DA-SA pairs with the associated receive port are programmed into  
the switch using Cabletron’s Automated Connection Management System  
(ACMS). This provides the network administrator with the ultimate network  
security without the performance degradation found when using routers or  
bridges with special filtering capabilities. The MMAC-Plus hub can support  
modules operating in bridge mode and SFPS mode simultaneously providing  
security when/where needed and ease of configuration where security is not  
required.  
i960 Core  
The i960 core provides the SNMP protocol stacks, to support industry standard  
MIBs. Additionally, Cabletron enterprise extension MIBs are supported for each  
media type. Advanced management services, such as the Distributed LAN  
Monitor, telnet and network address to MAC address mapping, are also provided  
by the i960 core.  
3-3  
 
Operation  
The Host engine sends and receives packets via the CPU FPS Interface. This  
allows the bridge to perform spanning tree protocol and other bridging functions.  
The SMB Interfaces provide communication to the Host Engine for management  
functions and communication with other modules in the chassis.
