Cabletron SNMP Bridges
Management Module Guide
Chapter 1
Introduction
What is in this Chapter
This chapter describes the SPECTRUM Management Module for the
Cabletron SNMP Bridge family of devices. It also provides the Model Type
Names assigned to the SNMP Bridges in SPECTRUM. The Model Type Name
refers to the template used to specify device attributes, actions, and
associations for device models in SPECTRUM.
SNMP Bridge Management Module
The SPECTRUM SNMP Bridge Management Module manages the Cabletron
SNMP Bridge family of devices by using the SNMP network management
agent and the Management Information Bases (MIBs), included with the
management module.
There are four SPECTRUM model type names for the Cabletron SNMP
Bridge Devices, three for the standalone models (Bdg_CSI_SNB20,
Bdg_CSI_SNB25, BdgCSINB30), and one for the MMAC chassis module
(Bdg_CSI_EFDMIM).
Bdg_CSI_SNB20: An NB20E bridge managed through the Simple Network
Management Protocol (SNMP).
Bdg_CSI_SNB25: An NB25E bridge managed through SNMP.
BdgCSINB30: An NB30 T1 Remote Bridge managed through SNMP. Most
functions are like the NB25E but there are some differences noted throughout
the manual. NB30 bridges work in pairs.
9030368 E9
Introduction
1-1
SNMP Bridge Management Module
Bdg_CSI_EFDMIM: An EFDMIM Ethernet to FDDI bridging MIM designed
for installation in a Cabletron MMAC hub device and managed through
SNMP.
If you are running a previous version of SPECTRUM, the following user
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 SPECTRUM Views and SPECTRUM Menus.

Device View
What is in this Chapter
This chapter provides a description of the Device View for the SNMP Bridges
Management Module. This description includes an explanation of the menu
bar access to the various views used to control and monitor the bridge, and
how to use the Device View to view EFDMIMs, access SPECTRUM generic
views, and monitor the performance of the bridges.
The Device View shows an actual representation of the bridge configuration.
The representation is updated after each SPECTRUM polling cycle to show
any changes in the bridge configuration.
Accessing the Device View
You can access the Device View using one of the following methods (refer to
Figure 2-1 ):
• Double-click on the Device View button of the bridge icon.
• Highlight the bridge icon and select Device from the Icon Subviews
menu.

SNMP NB20E and NB25E Device Views
This view represents the physical status of the SNMP Bridge device and
provides menu access to the generic views. These generic views allow you to
access network configuration information as well as traffic flow and error data
for your bridge. The Device View creates an icon manager that represents
each of the ports associated with the bridge model.
The Device View periodically polls the bridge model in the SpectroSERVER
database to determine if any configuration changes have occurred. If a
configuration change has occurred, the configuration is changed within the
Device View to match the model in the SpectroSERVER database. Figure 2-2
provides and example of an SNMP Bridge NB-20E Device View.

EFDMIM Device View
EFDMIM Device View
The EFDMIM is displayed in the Device View for a Cabletron hub. The hub
Device View shows an actual representation of the hub with an EFDMIM
installed in one of the slots. If the configuration changes (e.g., if an EFDMIM
board is pulled or added to the hub), you see the corresponding change within
this view. This change in the view occurs after the model’s next poll cycle.
This view represents the physical status of the EFDMIM installed in a
Cabletron hub chassis and provides menu access to the EFDMIM generic
views. These generic views allow you to access network configuration
information, as well as traffic flow and error data for your EFDMIM.
Depending on the type of Cabletron hub containing the EFDMIM, the Device
View appears slightly different. The Cabletron hub categories are as follows:
•
•
IRM2, IRBM, or IRM3
IRM
The Device View periodically polls the hub model in the SpectroSERVER
database to determine if any configuration changes have occurred. If a
configuration change has occurred, the Device View changes as well to match
the model in the SpectroSERVER database.
Accessing the Hub Logical/Physical Device View
You can access the Hub Logical or Physical Device View using one of the
following methods (refer to Figure 2-4):
• Double-click on the Device View button of the hub icon. This opens the last
device view accessed.
• Highlight the hub icon and select Device -> Logical or
Device -> Physical from the Icon Subviews menu.

To receive EFDMIM gauge and port information in the IRM2 or IRM3 Device
View logical representation and for the EFDMIM LEDs to appear “live” in the
IRM2 or IRM3 Device View physical representation, you must configure the
EFDMIM installed in the hub chassis. The EFDMIM can only be configured in
a Topology View. To configure the EFDMIM, execute the following procedures:
1. In the same Topology View level as the IRM2 or IRM3 with the installed
EFDMIM, create a stand alone icon representing the EFDMIM.
2. In Edit mode, create a logical connection pipe between the stand alone
EFDMIM icon and the IRM2 or IRM3 icon representing the hub with the
installed EFDMIM. SPECTRUM automatically connects the EFDMIM to
the hub’s internal port (CSIRptr Port).
3. In the EFDMIM DevTop view, connect the Off-Page Reference Icon
representing the IRM2 or IRM3 containing the EFDMIM to the EFDMIM
Ethernet port.
This completes the configuration procedure. Current EFDMIM gauge and port
information in the IRM2 or IRM3 Device View logical representation is now
provided. The EFDMIM LEDs in the IRM2 or IRM3 Device View physical
representation will now appear active.

To change the MIM representation of the entire hub Device View, follow these
steps:
1. In the hub’s Physical Device View, select the Device Menu menu option.
2. Click on either the Display Physical MIMs or Display Logical MIMs
menu option. The entire hub changes to the selected MIM representation.
Changing MIM Representations Using the Menu Bar
To change the MIM representation of the EFDMIM using the menu bar, follow
these steps:
1. In the hub’s Physical Device View, move the mouse pointer onto the
EFDMIM. Single-click the left mouse button to highlight the EFDMIM.
2. Select the View menu, and select the Icon Subviews submenu. Select the
Go Logical menu options from this submenu.

Changing MIM Representations Using the Mouse
To change the MIM representation of the EFDMIM, using the mouse, follow
these steps:
You must start in physical representation to use this toggle feature.
NOTE
1. Move the mouse pointer onto the EFDMIM.
NOTE
Make sure that the mouse pointer is not on top of or next to a gauge or port
connector, otherwise a Port Performance View will open.
2. Double-click the left mouse button.
3. The EFDMIM changes its representation. A selected single MIM appears
to extend from the hub chassis.
Clearing Duplicate EFDMIM Address Alarms
If you have previously created a stand alone EFDMIM icon and have created
an IRM or IRBM hub icon and configured the EFDMIM installed in that hub
through the hub Device View, a duplicate address alarm condition (yellow
alarm) now exists in the hub icon containing the EFDMIM or the stand alone
EFDMIM icon. This occurs because SPECTRUM views the independent
EFDMIM icon and the EFDMIM installed in the hub icon as separate devices
with the same assigned IP address. To alleviate this alarm condition, you
must clear the duplicate alarm.
NOTE
9030368 E9
Although yellow alarm conditions are minor alerts, Cabletron Systems
recommends clearing these alarms when they occur.
Device View
2-29
EFDMIM Device View
Clearing Duplicate EFDMIM Address Alarms
Two methods exist for clearing this yellow alarm condition, depending on the
procedural order in which you created the independent EFDMIM icon and
configured the EFDMIM in the IRM or IRBM hub Device View. The particular
EFDMIM showing the duplicate IP address yellow alarm condition depends
on which EFDMIM was created or configured first. The following sections
describe the two possible ways of creating EFDMIMs and how to clear the
resulting duplicate alarms.
Case #1
1. Create the independent EFDMIM (Bdg_CSI _EFDMIM) icon.
2. Create the IRM or IRBM hub icon that contains the EFDMIM.
3. Configure the EFDMIM in the hub Device View.
If you followed the previous procedure, you can clear the duplicate address
alarm as follows:
1. Navigate to the hub Device View containing the EFDMIM.
2. Click on the EFDMIM to highlight it.
3. Select Icon Subviews from the View menu.
4. Select MIM Diagnostic View to access the EFDMIM Diagnostic View.
5. Select Alarms from the EFDMIM Diagnostic View. The Alarm View
displays an alarm icon for the EFDMIM installed in the hub with a yellow
alarm contact status color. The Symptom/Probable Cause box displays a
DUPLICATE IP ADDRESS message.
6. Choose the Clear option from the Tools menu to clear the alarm. You can
now exit from this view.
Case #2
1. Create the IRM or IRBM hub icon that contains the EFDMIM.
2. Configure the EFDMIM in the hub’s Device View.
3. Create the independent EFDMIM (Bdg_CSI_EFDMIM) icon.
4. If you followed the previous procedure, the EFDMIM (Bdg_CSI_EFDMIM)
icon appears with a yellow alarm contact status in the Topology View. You
can clear the duplicate address alarm as follows:
5. Click on the stand alone EFDMIM (Bdg_CSI_EFDMIM) icon.
6. Select Icon Subviews from the View menu.

Chapter 3
Application Views
What is in this Chapter
This chapter describes the Application Views available for all Cabletron
SNMP Bridges. The Application View contains network protocol traffic and
database information for the Cabletron bridge device. Some of these attributes
are external to SPECTRUM, since they are entered when the bridge device is
configured. Other attributes are internal, since they are entered when the
bridge device’s icon is created in the SpectroSERVER database. In the NB30 a
filtering database is not maintained by the device on frames received through
port 2 (the remote port). Consequently, filtering cannot be enabled or disabled

Event and Alarm Messages
What is in this Chapter
This chapter describes the events and alarms that Cabletron SNMP Bridge
devices generate. Additionally, this appendix notes if an event is mapped to an
identical alarm message, and provides any probable cause messages
corresponding to these alarms.
The events and alarms generated by the model type designations listed below
are described in the sections that follow:
• SNMP NB20E
• SNMP NB25E
• NB30
Events and alarms originate as generic Simple Network Management
Protocol (SNMP) traps sent from the physical bridge device. SPECTRUM
translates these traps, or unsolicited messages, as events and displays them
in the Event Log. The EFDMIMdoes not support traps. For more information
on specific traps generated by each device, refer to RFC 1213 available
through the Internet system. Also refer to the Management Information Base
(MIB) documentation for each specific bridge device.
NOTE
9030368 E9
Each event/alarm listed below includes: the event code, the event/alarm
message, followed by a brief description of the event/alarm, an alarm
mapping indicator, and any probable cause message for the mapped alarm.
When variable data is inserted in a message, it is indicated by a {v}. Data in
parenthesis will be replaced by the named variable followed by a specific
value, without the parenthesis.
