Chapter 1

Introduction

What is in this ChapterThis 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 ModuleThe 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.

SNMP Bridge Management Module

Introduction1-2


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.

9030368 E9 Device View2-1

Chapter 2

Device View

What is in this ChapterThis 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 ViewYou 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.

Figure 2-1. Accessing the SNMP NB20E/NB25E/NB30 Device View

SNMP NB20E and NB25E Device ViewsThis 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 ViewThe 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 orDevice -> Physical from the Icon Subviews menu.

7. A Pop-Up Window appears and prompts you whether to save the updated configuration information. Click OK.

8. Select Go Back from the View menu in the EFDMIM Configuration View to close this view.

Current EFDMIM gauge and port information in the IRM or IRBM Device View logical representation will now be provided. The EFDMIM LEDs in the IRM or IRBM Device View physical representation will now appear active.

Configuring the EFDMIM in an IRM2 or IRM3

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.

NOTE

Once the EFDMIM has been configured in the Topology View, the stand alone EFDMIM icon and the IRM2 or IRM3 icon containing the EFDMIM can be copied into a Location View.

Changing MIM Representations

You can change the MIM representation of the entire hub or the MIM representation of the EFDMIM installed in the hub. This section describes several ways to change the representation of MIMs in a hub.

Changing MIM Representations on the Entire Hub

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.

3. The EFDMIM changes its MIM representation. A selected single MIM appears to extend from the hub chassis.

NOTE

You must start in physical representation to use this toggle feature.


EFDMIM Device View

Clearing Duplicate EFDMIM Address Alarms

Changing MIM Representations Using the Mouse

To change the MIM representation of the EFDMIM, using the mouse, follow these steps:

1. Move the mouse pointer onto the EFDMIM.

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

You must start in physical representation to use this toggle feature.

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.

NOTE

Although yellow alarm conditions are minor alerts, Cabletron Systems recommends clearing these alarms when they occur.

EFDMIM Device ViewClearing Duplicate EFDMIM Address Alarms

Device View2-30


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.


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.

Chapter 3

Application Views

What is in this ChapterThis 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 for that port and all frames received through that port are automatically forwarded to port 1 (the local port).

Accessing the Application ViewYou can access the Application View using one of the following methods (refer to Figure 3-1):

• Double-click on the Application View label of the bridge icon.

• Highlight the bridge icon and select Application from the Icon Subviews menu.

9030368 E9 Event and Alarm Messages7-1

Chapter 7

Event and Alarm Messages

What is in this ChapterThis 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

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.
