This chapter describes the SPECTRUM Management Module for the
Cabletron Ethernet Hub family of devices. It also provides the Model Type
Names assigned to the hubs in SPECTRUM. The Model Type Name refers to
the template used to specify device attributes, actions, and associations for
device models in SPECTRUM.
Chapter 1
Cabletron Ethernet Hubs Management Module
The SPECTRUM Ethernet Hubs Management Module manages the
Cabletron Ethernet Hub family of devices by using the SNMP network
management agent and the Management Information Bases (MIBs), included
with the management module.
Table 1-1 provides the Model Type Names for the Cabletron Ethernet hubs
and a brief description of the intelligent hub module devices supported by the
Cabletron Ethernet Hubs Management Module.
(IRBM) managed through the Simple Network
Management Protocol (SNMP) only. This
module includes bridging functionality that is
similar to a Cabletron SNMP NB25.

If you have installed both the Hub_CSI_MRXi (Cabletron Ethernet Hubs
NOTE
Management Module) and the HubCSIMRXi (MRXI-24 Management
Module), and are going to model an MRXI or MRXI-2, make sure you select
the Hub_CSI_MRXi (MRXI/MRXI-2) model type from the Select Model Type
menu, NOT the HubCSIMRXi (MRXI-22 or 24) model type.
If you are running a previous version of SPECTRUM, the following user
NOTE
interface aspects may differ from those in SPECTRUM version 4.0:
• Order and names of menu selections
• Navigational features (mouse button functionality)
For information about menu selections and navigating within previous
versions of SPECTRUM, refer to the SPECTRUM System User’s Guide. For
information about menu selections and navigating within SPECTRUM
version 4.0, refer to the SPECTRUM Operator’s Reference.
Terminology
This section defines several terms used in this guide to describe Cabletron
The software model representation of an MMAC with no boards installed in
its slots. An MMAC chassis can have three, five, or eight slots.
Media Interface Modules (MIMs)
The software model representations of boards installed in an MMAC hub
chassis. For the purposes of this guide, the term MIM will represent all MIMs
that can be installed in a Cabletron hub.
Intelligent MIMs
MIMs that provide network management functions and network media
interfacing.
Non-intelligent MIMs
MIMs that provide interfaces to different kinds of network media, but have no
network management capabilities.
Single-Port Interface Modules (SPIMs)
For the MRXI and MiniMMAC hubs, this term is used to represent the nonintelligent MIMs that can be installed in these hub chassis types.
This chapter provides a description of the Device View for the Cabletron
Ethernet Hubs Management Module. This description includes an
explanation of the menu bar access to the various views used to control and
monitor the hub devices, and how to use the Device View to view the logical
and physical representations of Cabletron hubs, access SPECTRUM generic
views, and monitor hub performance. It also points out differences in the
Device Views of various Cabletron hubs.
Chapter 2
Accessing the Device View
You can access the Device View using one of the following methods (refer to
Figure ):
• Double-click on the Device View button of the icon. This opens the Device
View last accessed (i.e., Logical or Physical Device View) for this device.
• Highlight the icon and select Device -> Logical or Device -> Physical
from the Icon Subviews menu. The Hub_CSI_MRXi and Hub_CSI_ MiniM
model types do not support the Logical/Physical submenu, and provide
access to the Logical Device View through the Device menu item.

Ethernet Hubs Device View Description
The Device View for a hub allows you to view a logical or physical
representation of the Media Interface Modules (MIMs) installed in a hub. The
logical MIM representation shows a port status label and a logical gauge,
while the physical MIM representation shows the actual physical appearance
of the module and its LEDs. The Device View also provides you with menu bar
access to the views that monitor and control the hub, the hub modules and
each module port.
The Device View shows an actual representation of the hub configuration. The
representation is updated after each SPECTRUM polling cycle to show any
changes in the hub configuration. For example, if a module is pulled from or
added to the hub, the device view displays the new configuration. Figure
displays one example of a Cabletron Ethernet Hub Device View.

The colored rectangle that appears around these fields displays the device
contact status. For a list of device contact status colors, refer to Table 3-2.
The MMAC Device Panel also provides a Logical Gauges button and a
Gauge Mode button. These buttons allow you to change the type of statistical
information presented in the Logical MIM horizontal bar gauges. The Logical
MIM bar gauges appear under the name of the module (e.g., IRM2) and under
each module port. The following sections describe how these buttons work.
Logical Gauges
The Logical Gauges button lets you change the statistics represented in the
horizontal gauges for the entire MMAC. The horizontal gauges can display a
given statistic as either a percentage or a rate, depending on the setting of the
Gauge Mode button. When you single-click on the Logical Gauges button, a
menu appears. Table 2-1 provides a list of the Logical Gauge menu options.
Gauge Mode
The Gauge Mode button allows you to change the gauge representation of the
selected statistic. Table 2-2 provides a list of the Gauge Mode menu options.

Logical MIM Representation
The logical MIM representation provides information about the individual
modules. For information on the Device View physical MIM representation,
see the section titled “Physical MIM Representation.”
The logical MIM representation provides port status labels and double-click
zones that provide access to information on each module installed in the hub.
The logical MIM representation also provides several double-click zones that
function as follows:
Port Number
Indicates the port number. You can double-click on the port number to bring
up a notes window.
Port Status
Indicates the status of the port. You can double-click on this zone to bring up
the Port Performance view, which is described in Chapter 6. When you have
accessed the Logical MIM representation through the Physical MIM
representation, double-clicking the Port Status Label opens the Port
Administration Status dialog box. If you have write privileges, you can doubleclick on this zone to change the port administration status from ON to OFF or
from OFF to ON. Table 2-3 provides the port status values.
Indicates the frame rate for the port. You can change this display using the
Gauge Control Panel, which is described later in this chapter. When you have
accessed the Logical MIM representation through the Physical MIM
representation, the Port Performance label displays a gauge. The rates or
percentages measured by this gauge depend on the setting of the Logical
Gauges and Gauge Mode buttons. You can double-click on the Port
Performance Gauge to bring up the port performance view, which is described
in Chapter6.
