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

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-backedNon-VolatileRAM (NVRAM) forpreservingdata 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.
BridgingToken Rings InThe 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.

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 TRBMIM/TRBMIM-T Local Management

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.

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 InThe 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.

INTRODUCTION

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.
