1.4 TRBMIM-T OVERVIEW

The TRBMIM-T is two-port source-route bridge with management

capabilities. The two TRBMIM-T bridge ports are described as follows:

• The FNB backplane connector on the TRBMIM-T component board

interfaces with the FNB ring in the MMAC.

• The media-conﬁgurable Station port on the front panel interfaces with

another ring

via cable connection

to any lobe port on another ring,

regardless of whether the other ring is conﬁgured in the same MMAC

where the TRBMIM-T is installed or supported by another MMAC or

standalone hub. See Chapter 4 for information on how to set up the

bridge Station port and establish the physical bridge connection

between rings.

You can conﬁgure the TRBMIM-T to operate either as a dedicated

source-route bridge for linking Token Ring networks or as a combination

bridge and ring management module for both bridging and ring

management. It installs into any of the Media Interface Module (MIM)

slots of the following Cabletron Systems line of Multi Media Access

Centers:

• MMAC-M3FNB/-3FNB

• MMAC-M5FNB/-5FNB

• MMAC-M8FNB/-8FNB

See Chapter 2 for more information about MMAC requirements.

TRBMIM-T Features

TRBMIM-T features include:

• IBM Token Ring Network and source-route bridge compatibility

• IBM LAN NET Manager support

• SNMP-compliant in-band management support for remote

management applications

TRBMIM-T BOOK Page 4 Tuesday, July 2, 1996 10:35 AM

INTRODUCTION

1-5

• Local Management (LM) applications, accessible via:

- Out-of-band connection to the front-panel RS-232 Console port to

a VT-series terminal or a PC running a VT-series emulation

program

- In-band Telnet connection from any TCP/IP - based node linked to

the TRBMIM-T

• Selectable operating modes:

- Bridge/Management for bridging and ring management

- Bridge-Only for dedicated high-performance source-route

bridging

• Selectable Token Ring operating speeds of 4 Mbps and 16 Mbps for

the FNB port and the bridge Station port

• Media-ﬂexibility for the front-panel bridge Station port provided by

interchangeable, hot-swappable Cabletron Systems Token Ring Port

Interface Modules (TPIMs)

• Flash EPROM ﬁrmware enhancement capability via Trivial File

Transfer Protocol (TFTP)

• LANVIEW LED system monitoring and diagnostics system

• Boot PROM support for IP Auto-Conﬁguration from a BootP server

• Automatic Beacon Recovery Process (ABRP) restores network

functioning from beaconing conditions caused by hard errors detected

on the ring

• 24-MHz, 32-bit Intel i960 processor

• Battery-backed Non-Volatile RAM (NVRAM) for preserving data and

system conﬁguration settings

• Thermal sensors that detect overheating in the MMAC

1.4.1 Describing Bridge-Only Mode Capabilities

The Bridge-Only mode is the default operational mode for the

TRBMIM-T. When in the Bridge-Only mode, the TRBMIM-T serves

exclusively as a source-route bridge in the MMAC for linking separate

Token Rings. It neither automatically segments the FNB backplane nor

performs any of the ring-management functions available when operating

in the optional dual-function Bridge/Management mode.

Bridging Token Rings In The Same MMAC

Figure 1-2 illustrates how the TRBMIM-T can be used to bridge Ring 1

and Ring 2 in the same MMAC. In this conﬁguration the TRBMIM-T’s

FNB port is connected to Ring 2. Its front-panel bridge Station port is

connected to Ring 1 via cable to any lobe port on any MIM on Ring 1.

The TRMMIM is managing Ring 2.

NOTE

The ring identiﬁers, Ring 1 and Ring 2, in the following

examples are used for illustrative purposes only. They are not

intended to reﬂect or recommend an actual ring numbering

scheme. See the

Collapsed Backbone Conﬁguration

Figure 1-4 illustrates how multiple TRBMIM-Ts can be used in the

MMAC to constitute a single collapsed backbone ring to provide network

connectivity for multiple rings, running at either 4 Mbps or 16 Mbps ring

speeds and linked to the backbone via either twisted pair copper or ﬁber

media. In this conﬁguration each TRBMIM-T’s FNB port is connected to

a common FNB ring in the MMAC. Each TRBMIM-T’s front-panel

bridge Station port is connected to a separate ring via cable to any lobe

port on any MIM on each ring.

Figure 1-4 Collapsed Backbone Ring

1.4.2 Describing Bridge/Management Mode Capabilities

This section describes the optional functionality provided by the

TRBMIM-T when conﬁgured to operate in the combination

Bridge/Management mode. You can use the TRBMIM-T in the

Bridge/Management mode when you want to establish an additional

Token Ring in the MMAC that already supports either an Ethernet or a

Token Ring LAN. See Section 2.3 for Bridge/Management mode

requirements.

Management Functionality In The MMAC

When conﬁgured for operation as a combination Bridge/Management

module and installed in any MIM slot in the MMAC, the TRBMIM-T

automatically bisects the FNB backplane. This creates a new FNB ring,

supporting Token Ring stations connected to the media interface modules

inserted to the left of the TRBMIM-T.

The TRBMIM-T manages the new ring in conjunction with the

master-management module (Ethernet or Token Ring) installed in the

MMAC management slot. Token Ring management module functions

include:

• Collecting ring statistics

• Supporting in-band and out-of-band network management

• Sending traps and alarms to Network Management Stations

• Recovering from beaconing conditions

• Controlling modules and ports on the ring

• Maintaining ring and management security

See Section 2.5.1 for information about using dip switches on the

TRBMIM-T component board to specify the Bridge/Management mode

and other operational settings for the TRBMIM-T. See the

TRBMIM/TRBMIM-T Local Management User’s Guide

for

information on managing Token Ring MIMs under TRBMIM-T control.

Figure 1-5 illustrates how the TRBMIM-T in the Bridge/Management

mode can be used to bisect the MMAC FNB backplane and create an

additional FNB ring. The TRMM, installed in the management slot,

manages Ring 1 and the TRBMIM-T, installed in a MIM slot, manages

Ring 2.

TRBMIM-T BOOK Page 9 Tuesday, July 2, 1996 10:35 AM

INTRODUCTION

1-10

Figure 1-5 Ring Management in the MMAC

Bridging Functionality In Bridge/Management Mode

The TRBMIM-T performs the same source-route bridging functions

when in the Bridge/Management operational mode as it does when it is in

the Bridge-Only operational mode. The TRBMIM-T must simultaneously

perform both ring-management functions and bridging functions when in

the Bridge/Management mode. Consequently, its bridging performance

(data-transmission rate) does not equal the rate achieved when it is in the

Bridge-Only mode.

1.4.3 Monitoring And Troubleshooting Systems

LANVIEW LEDs, located on the TRBMIM-T front panel, provide an

at-a-glance method of monitoring the module’s operational status. LEDs

indicate, for example, whether the module is operating correctly and the

ring operating speed.

NOTE

For optimal bridging performance as required by your

bridged-ring installation, operation of the TRBMIM-T in the

Bridge-Only mode is recommended.
