How to use this guide; getting help; special features of MMAC-Plus Remote Management; related
reading

Welcome to the Cabletron Systems Using MMAC-Plus¨ Remote Management
Guide. We have designed this manual to serve as a simple reference tool for

remotely managing a Cabletron Systems MMAC-Plus Chassis with an installed
9C300-1 Environmental Modulesª and MMAC-Plus Client Modules (including
the 9E132 and 9E133 series Ethernet MicroLAN Moduleª, the 9T122 Series Token
Ring MicroLAN Moduleª, the 9F120 series FDDI Concentrator Moduleª, and
the 9F116 series FDDI Bridge/Router Moduleª).

The MMAC-Plus is Cabletron Systems latest generation network hub - a fourteen
slot chassis with an integrated backplane that supports LAN, WAN, SNA, and
ATM connectivity. There are four components to the backplane. Two components
are currently implemented: the Flexible Network Bus (FNB) Ñ composed of two
dual-FDDI networks that provide up to 400 Mbps of data bandwidth, and a two­channel System Management Bus (SMB) that is used by all components to
exchange status and environmental information, issue diagnostic messages,
provide intermodule communication, and synchronize chassis management.
There are two more components to be implemented in the near future: an Internal
Network Bus (INB), designed to support packet and ATM cell transport, and a
Cell Transfer Matrix (CTM), which will enable the MMAC-Plus to act as a
backbone ATM switch.

The MMAC-Plus is equipped with an Environmental Module that controls
system cooling, environmental monitoring, and provides out-of-band
management capability. Individual client modules provide management and
connectivity options for any network media or technology. No dedicated
management module is required for the hub as a whole.

1-1

Introduction

MMAC-Plus Remote Management capability for the chassis includes:

¥ A Chassis View, which allows you to see at a glance the connection status of

any installed MMAC-Plus client modules, as well as basic information about
the Environmental Module, including the status of its communication ports,
Ethernet EPIM port, and LCD read-out, and environmental conditions for the
chassis as a whole.

¥ An Environment View, which displays environmental information for the

individual client modules (including power consumption and operating
temperature), as well as fan speed and power supply management.

¥ A Backplane ConÞguration View, which shows how the installed client

modules are currently conÞgured with regard to the FNB backplane
component of the MMAC-Plus chassis, and allows you to change that
conÞguration.

¥ Access to Client Module-speciÞc management applications.

You should read this manual thoroughly to understand MMAC-Plus Remote
Management.

Using This Manual

This manual covers management operations directly related to the monitoring
and control of the chassis (including the conÞguration of client modules with
respect to the chassis). It also describes management functions that are shared by
most client modules, such as alarm and event monitoring.

This manual does not describe management operations that are inherent to
individual client modules. These operations are covered in separate management
module guides; refer to these guides for more information on managing an
individual module.

Chapter 1, Introduction, discusses the capabilities of Cabletron Systems MMAC­Plus Remote Management. It also lists related user manuals.

Chapter 2, Getting Started, discusses how to initially conÞgure MMAC-Plus
Remote Management through the Chassis Setup view.

Chapter 3, MMAC-Plus Management Views, describes viewing and using the
Chassis, Environment, and Backplane ConÞg views of MMAC-Plus Management.

We assume that you have a general working knowledge of data communications
networks and their physical layer components.

Getting Started

Configuring the Chassis Setup window to run MMAC-Plus Remote Management

This chapter describes setting up the Chassis View to run remote management.

Initiating MMAC-Plus Remote Management

For this release of MMAC-Plus Remote Management, Þrmware limitations of the
MMAC-PlusÕs on-board System Management Bus components do not allow an
individual IP address to be assigned to the chassis as a whole. This affects remote
management of an MMAC-Plus chassis in two ways:

Chapter 2

TIP

¥ First, as there is no IP address for the chassis as a whole, discovery from your

Cabletron management platform (e.g., Remote LANVIEW/Windows) is

incapable of automatically creating an icon (and associated Hub View) to model

a conÞgured chassis (individual modules are discovered and created as SNMP

devices).

¥ Second, when you initialize a Chassis View for MMAC-Plus management,

you must conÞgure it with a hub name, along with the IP address and type

of each module installed in the chassis. This information is stored in a

conÞguration Þle in your Cabletron management application database (e.g.,

C:/RLW/BIN/CHASSIS1.MMP).

Prior to installing a new version of your Cabletron Management Application, be sure that
your *.MMP conÞguration Þles are backed up to a directory other than the default data
directory; otherwise they will be overwritten on the new install.

When you initialize the MMAC-Plus Remote Management, you must either

conÞgure a new MMAC-Plus chassis, or select a previously conÞgured

MMAC-Plus chassis to monitor and manage. Once a chassis has been

conÞgured (and its *.MMP conÞguration Þle subsequently created), you will

be able to monitor and manage it via the management views described in the

following chapter.

2-1

Getting Started

To initiate an MMAC-Plus Remote Management session:

1. Select Utilities —> MMAC-Plus from your Cabletron management
application’s main menu.

2. The Chassis Entry window (Figure 2-1) will appear, with a drop-down menu
list of configured chassis that are available for management. When you
initially launch MMAC-Plus Remote Management, only the default entry of
“Chassis” will display in the list, as no other devices have been configured.

3. To configure an MMAC-Plus Chassis for remote management:
a. In the Enter chassis name: field, type in a unique descriptive name (up

to eight characters) to represent the chassis. This name is only used to
identify the chassis by name (and to identify the *.MMP configuration file);
it is not set at the device.

Figure 2-1. Chassis Entry Window

b. Click OK. The Chassis Setup window will appear (see the example in

Figure 2-2 — this window displays a configured chassis; a new chassis
would be blank, with no fields configured).

c. For you to successfully model your MMAC-Plus chassis and its client

modules, you must match its precise configuration in the Chassis Setup
window. In the row corresponding to the appropriate chassis slot (labelled
1 to 14 at the left of the window), do the following:

2-2 Initiating MMAC-Plus Remote Management

Getting Started

Figure 2-2. Sample Chassis Setup Window

- Click on the Module Type drop down list box, and drag to select the
appropriate module type for the device installed in the corresponding
slot (currently the 9E132 and 9E133 series Ethernet MicroLAN
Module, 9F120 series FDDI Concentrator Module, 9F116 series
FDDI Bridge/Router Module, and 9T -122 series Token Ring MicroLAN
Module. Bridge and FDDI support is also available for the 9A128
series ATM Module; although this module has not been documented,
its current functionality is identical to the 9F116 module. Other
modules are not yet supported via Remote Management).

Note that when you select a module, its community name field will
automatically default to public.

- In the IP Address field, type in the network address assigned
to the client module installed in the corresponding slot. Make
sure the address is in valid dotted decimal notation format (i.e.,
XXX.XXX.XXX.XXX, where XXX ranges from 1 to 254).

- The Community Name field will be used in future releases of MMAC­Plus Remote management. The SNMP Community Name acts as
both the local and remote password with which you can manage the
device. For information on setting your client module’s community

!

CAUTION

Each module must be correctly set up in the Chassis Setup window with the correct slot
number, type, IP address, and community string.

If you do not conÞgure these parameters correctly for a module, and then exit the Chassis
Setup window, the module will not be displayed in the Chassis window. The Chassis
Setup window will reappear automatically to inform you of a conÞguration problem. Any
incorrectly described module will appear highlighted in red, and will have a button to
its right.

Clicking on will display one of four status messages at the bottom of the window, (as
shown in the example below):

Device is actually in slot X indicates that the device IP has been detected in the chassis,
but the device is installed in a different slot than the one which was conÞgured.

IP address or Community Name is invalid indicates that the device IP address given
was not found in the MMAC-Plus chassis (community names are not used at this time).

Device is not a MMACPlus module indicates that the device that you have identiÞed
in the chassis is not an MMAC-Plus architecture device.

Wrong device type indicates that you have selected the wrong type for the conÞgured
device from the Module Type pull-down menu.

These errors will also be reßected in the Chassis Setup window if a chassis that you had
previously modelled has been physically re-conÞgured between management sessions, so
that the modelled chassis is inaccurate.

Reset the Chassis Setup window so that the correct conÞguration of your MMAC-Plus
chassis is modelled.

names, refer to its

is the only community name supported by remote management.

d. Click OK to save configuration changes to the device database, and to

begin modelling the defined MMAC-Plus chassis.
Note that the next time you initialize MMAC-Plus Remote Management,

the name of the configured chassis will appear in the Enter chassis
name drop-down list menu at the introductory screen.

The Chassis Setup window will disappear, and a new management view will
appear for the MMAC-Plus Chassis. Refer to Chapter 3, MMAC-Plus
Management Views, for more information on managing your MMAC-Plus
chassis.

MMAC-Plus Management Views

An overview of MMAC-Plus Management views; changing the current view; changing the default start­up view; the Chassis View; the Environmental View — the Module Power View, the Module
Temperature View; the BackPlane Configuration View; initializing individual module management
applications.

With MMAC-Plus Remote Management, you can switch between three different
views of your hub to retrieve information:

¥ A Chassis View allows you to scan the connection status of any installed

MMAC-Plus client modules, and view basic information about the
Environmental Module (including the status of its communication ports,
Ethernet EPIM port, and LCD read-out) and environmental conditions for the
chassis as a whole.

¥ An Environment View displays environmental information for the individual

client modules (including power consumption and operating temperature),
and lets you view and manage the fan speed and power supplies.

¥ A BackPlane ConÞguration View displays, and lets you change, how the

installed client modules are currently conÞgured in respect to the dual ring
FDDI backplane of the MMAC-Plus chassis. It also lets you wrap the FNB
rings by switching the backplane multiplexers of each module installed in the
chassis.

An Overview of Management Views

Each MMAC-Plus Management view is divided into four sections (as shown in
Figure 3-1): General Information, Environmental Module Status, Client Module
Status, and System Status. This section discusses the general information at the
top of each window that is common to all three management views. It also
discusses how to change the current management view, and how to change the
default view when MMAC-Plus Management is initialized.

General View Information

The following Þelds appear in the general section of each management view. The
other three sections of the window vary with each management view and are
described in the individual view sections.

For this release of MMAC-Plus Remote Management, Þrmware limitations of the
MMAC-PlusÕs on-board System Management Bus components do not allow an
individual IP address to be assigned to the chassis as a whole; therefore, some
system information that would normally be reßected in these Þelds is unavailable
to remote management.

Other information is read from the Þrst module that MMAC-Plus Remote
Management detects in the chassis upon initializing.

Fields in the general information section of each view include:

Name

This Þeld displays the Þrst detected moduleÕs System Description Ñ a read-only
hardware/Þrmware device description (MIB II Ñ> System Ñ> sysDescr).

If no module is detected in the chassis, this displays the name that you assigned to
the conÞgured MMAC-Plus via the Enter chassis name Þeld (see page 2-2).

Net Address

This Þeld is currently unused. It will read 0.0.0.0.

3-2 An Overview of Management Views

Location

An administratively assigned description of the Þrst detected client moduleÕs
location (set via the MIBIIÑ>SystemÑ>sysLocation object). Refer to your client
moduleÕs MMAC-Plus Guide for information on changing the moduleÕs location
name.

Up Time

The duration, in a days hh:ss:mm format, that the Þrst module detected in the
MMAC-Plus chassis has been powered up.

You will also notice a Status Bar at the bottom of the Chassis View. This status bar
will provide contact status information for the modules conÞgured in the chassis.

Changing the Current View

You can change the view between the Chassis, Environmental, and BackPlane
ConÞguration Views, as well as re-open the Chassis Setup View, as follows:

1. Click on the View drop-down list box in the lower right of the MMAC-Plus
window , and drag down to select Chassis , En vironment, Bac kplane Config,
or Chassis Setup. The selected view will immediately appear.

MMAC-Plus Management Views

or

1. Click on View in the menu bar at the top of the MMA C-Plus window , and dr ag
down to select the desired view: Chassis, Environment, Bac kplane Config,
or Chassis Setup. A check will appear next to the selected view.

Changing the Default View

When you Þrst install MMAC-Plus Remote Management, the Chassis View is
selected as the default view when the application is initialized. You can select
another view to come up as the default view when MMAC-Plus Remote
Management is initialized. To do so:

1. Click on Options in the menu bar at the top of the MMAC-Plus window, drag
down to select Default View and to the right to select the desired view:
Chassis, Environment, or BackPlane Config. A check will appear next to
the selected default view.

Note that selecting a default view will not switch the currently active view; it
will take effect the next time you initiate an MMAC-Plus management session.

An Overview of Management Views 3-3

MMAC-Plus Management Views

The Chassis View

The Chassis View (Figure 3-2) provides you with an overview of the
environmental module status, backplane status, and operating status of any

Client Modules

When Chassis View is selected, the Client Module portion of the window will
display the operational status of each installed module and its supported ports.

Chassis slots are indexed from 1 to 14 in the middle of the Chassis window. If a
module is installed, its slot index will be color-coded to reßect operational status,
a module description will appear above the index, and a color-coded port display
will appear (the color-coding will vary, depending on which type of module is
installed).

Note that modules are polled at an interval of 10 seconds for operational status
and conÞguration. At each interval, MMAC-Plus Remote Management attempts
to contact the chassis modules three times before indicating a failed connection.

Module Index Color Codes

If a module is installed, its index Þeld will be color-coded to reßect the operational
status of the installed module:

Green The installed module is operational.

Red The module is not operating, or has not responded to a management

poll within the number of retries.

Yellow The module has experienced an alarm or trap condition, or it has

failed its power-up diagnostics test.

Ethernet, FDDI, and Token Ring Bridging Modules Port Display Color Codes

Port color-coding for Ethernet, FDDI, or Token Ring bridging modules indicates
the state of bridging across each interface supported by the module. Refer to the
individual MMAC-Plus Remote Management module manual for more
information on bridge operations.

Green The port is on-line and forwarding packets across the module from

one network segment to another.

Red The port has been disabled by management; no trafÞc can be received

or forwarded on this port.

Yellow The Forwarding database is being created, or the Spanning Tree

Algorithm is being executed because of a network topology change.
The port is monitoring network trafÞc, and learning network
addresses.

Fan Status/Speed

The Environmental Module adjusts the speed of the four system cooling fans
based on the external ambient temperature. Fan speed increases to ensure
adequate system cooling as ambient temperature rises; conversely, it decreases as
ambient temperature falls. If the ambient temperature sensor Ñ or the
Environmental Module itself Ñ fails, a switch increases the fan system to full
speed.

The Fan Status/Speed Þeld displays the current operating speed of each fan as a
percentage of maximum operating speed. The current operating speed and status
is color-coded as shown in the table below.

It also allows you to administratively set the fans to full operating speed or auto
speed (controlled by ambient temperature level sensor). To do so:

Priority Number

The Priority Number component of the module power system lets you assign the
moduleÕs priority in terms of the total MMAC-Plus power subsystem.

When the MMAC-Plus Chassis is powered-up, each DC-to-DC power converter
on its installed modules will request permission to initialize according to their
assigned priority (by default, modules initialize in slot order, 1 through 14). When
full system power consumption is reached, no more modules will be allowed to
initialize their DC-to-DC converters.

Priority also affects the use of back-up system power. When battery back-up takes
effect (either UPS or BBU), modules can be disabled in priority order to conserve
total system power.

The BackPlane Configuration View

The BackPlane ConÞguration View (Figure 3-6) allows you to view and conÞgure
how individual modules connect to the MMAC-Plus Flexible Network Bus (FNB).
From this window, you can also view and conÞgure the FNB as a whole Ñ
segmenting it across the backplane to form one or more smaller FDDI rings.

The Flexible Network Bus consists of two dual FDDI networks (FNB-1 and
FNB-2). Each network consists of primary and secondary counter-rotating rings
which can be used as separate networks (unless data-wraps occur, in which case
primary and secondary combine to form a ring). Modules connected to the FNB
can access any of the four available rings (primary and secondary rings for both
FNB-1 and FNB-2), so full aggregate bandwidth across the FNB is 400 Mbps
(4 x 100 Mbps).

All client modules Ñ regardless of their front panel media or LAN type Ñ either
bridge or route onto the FNB, or attach directly to the FNB. Depending on their
conÞguration, MMAC-Plus client modules can either attach to one or both of the
FNB channels, or bypass the bus entirely. This allows the FNB to traverse multiple
MMAC-Plus hubs, or inexpensively connect to any ANSI FDDI-compliant device.

Configuring the 9E133-36 Module

The 9E133-36 Ethernet MicroLAN module provides three 12 port ÒMicroLANsÓ
which are bridge routed between each other and onto one of the two backplane
FNB networks via a dual-attached bridging/routing interface. This interface
attaches simultaneously to both the primary and secondary FDDI ring of FNB-1
or FNB-2. The interface is also encoded with MAC (Media Access Control)
protocol information. The primary function of the MAC layer is to deliver frames
for stations attached to the 9E133-36. This involves inserting frames into the ring,
removing frames from the ring, and repeating frames. The MAC provides
attached stations access to the FDDI ring in a fair and structured manner;
provides address recognition for incoming frames; and generates and veriÞes
frame check sequences.

chapter for more information). If the slot is empty, its index will remain gray. Note
that a moduleÕs operational status does not effect your ability to conÞgure the
FNB multiplexers associated with its particular slot.

The Flexible Network Bus itself is represented by two sets of concentric rings; the
top set representing FNB-1(blue ring is primary; green is secondary) and the
bottom set FNB-2 (magenta ring is primary; yellow is secondary).

Figure 3-11. Sample FNB ConÞguration Window

Each moduleÕs MAC encoding is also indicated on the display. In the example
window on the previous page, module 1 is a 9E133-36 with MAC encoding
associated with FNB-2 primary, module 4 is a 9F120-08 with MAC encoding
associated with FNB-1 secondary (hidden by the menu), and module 7 is a dual­attached 9F116-01 (two interfaces connected to the FNB) with its two MACs
associated with FNB-1 primary and FNB-2 primary.

To segment the backplane FNB:

1. Click the left mouse button on the interface index where you want to segment
the ring, and drag to select the segmentation option of choice: Wrap FNB 1
Right, Wrap FNB 1 Left, FNB 1 Thru, Wrap FNB 2 Right, Wrap FNB 2 Left,
or FNB 2 Thru.

The example window below displays the consequence of wrapping the
left FNB multiplexer on board 1 (as shown in the menu of Figure 3-11). At
module 1’s FNB multiplexer, Primary In has wrapped to Secondary Out,
causing the primary and secondary rings to consolidate into a single ring
(essentially doubling the length of the initial primary ring). Any network
communications that were isolated on separate rings are now integrated into
a single ring (notice that both MACs are now associated with the same ring).

2. If you want, you can continue configuring FNB multiplexers, as shown in

Figure 3-13 (FNB-1 Right multiplexer wrapped at slot 1) and Figure 3-14
(FNB-1 Right multiplexer wrapped at slot 4). By wrapping multiplexers, you
can create two or more individual rings on each FNB (note that the rings will
not have redundancy, however).

3. When you have finished configuring the ring, click on Apply at the bottom of

the FNB Ring Configuration window . If you ha v e selected a legal configuration
of the ring, the FNB will be reconfigured as designed.

Accessing Module-specific Management Windows

You can access module-speciÞc management windows from any MMAC-Plus
Chassis view:

1. Click the left mouse button on a module index. You can be sure that it is the

module of interest by checking the Slot IP field in the low er right corner of the
view. A pull-down menu will appear.

2. Drag to select Device View . The main management window will appear for

the selected module.

For further information on managing an individual client module, refer to your
individual MMAC-Plus Remote Management Guide for that module.
