Management Module Guide

Chapter 1

Introduction

What is in this Chapter

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.

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.

Device Views

What is in this Chapter

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.

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.

Hub Redundancy Management

The hub redundancy management features described in this section include information specific to the following Cabletron hub devices:

• IRM2

• IRM3

• MRXI

• MiniMMAC

NOTE

The SIRM and the IRBM hub devices do not have redundant circuit compatibility available in their device firmware.

9030367 E8

SPECTRUM allows redundant “circuit” connections between any two or more hub devices that have redundant capability in their firmware. A circuit is represented by a cable connection from one module port on a primary hub device to one or more module ports on secondary hub devices. The cable connections can use any valid cable type, including thin-net, coaxial, fiber optic, or AUI. The terminating connectors used depend on the type of cable connecting the module ports.

Any two or more cable connections create a complete circular “circuit” pathway between the two devices. One pathway is always set up as primary and the others as secondary. The secondary circuit becomes active if the

Configuration Views

4-21

Hub Redundancy Management primary pathway fails. This allows the primary hub device to repeat data packet information on an alternative module port if a problem exists on the primary port.

Although circuit connections typically occur between devices in the same room, the circuit connections can also occur over longer distances between floors or buildings (with the proper FDDI cables and associated modules).

Refer to Figure 4-2 for an illustration of a typical redundant cable circuit

connection between two redundant hub devices.

Secondary Hub Device

The following example illustrates redundancy between hubs.

Say that you have used redundant circuit management to create a connection between the Accounting Department and the Payroll Department of your company. These departments are on the same floor and have two repeaters between them on an Ethernet network. Suppose a system overload occurred

Configuration Views

4-23

Hub Redundancy Management

Setting Redundant Circuits when you were sending direct deposit payroll information from the Payroll

Department to the Accounting Department the night before payday. This could be a disastrous situation.

Redundant circuit management would prevent this situation by allowing the primary hub device to automatically switch from the primary circuit to the secondary circuit. The backup circuit would become active and continue sending data over its cable connection. Redundancy becomes especially important for unattended night time batch jobs, or for jobs where a communications problem could seriously interfere with normal business operations.

Setting Redundant Circuits

The following procedure uses an IRM2 hub device as an example. However, this procedure can also be used with MRXI and MiniMMAC hubs as primary devices. The secondary device can be any hub device with redundancy capability (e.g., MRXI, MiniMMAC, IRM2, IRM3). This procedure may also be used to configure multiple secondary hub devices.

NOTE

These instructions assume that you have a primary MMAC hub module port physically attached to a secondary MMAC hub module port. Both these modules must have redundant circuit capability. The backup port connection cannot be completed until you have set up the active connection in

SPECTRUM. For convenience, you should also prepare a list of secondary hub

Ethernet addresses before beginning this procedure.

Also, SNMP devices require the use of the Community Name attribute. The

SPECTRUM default of “public” grants read-only privileges, which allow you to view device attributes, but not modify them. Since setting up redundancy requires modifying the device attributes, you should set the Community Name to “ctron,” which grants read/write privileges. You can set the Community

Name when you create the device or change it in the Device Configuration

View.

To set redundant circuits for the devices modeled in SPECTRUM, follow these steps:

1.

Click on the icon to select it.

2.

If contact has been established and the icon is green, bring up the

Configuration View.

3.

From the Configuration View menu, click on the Redundancy button. In the Redundancy View window, click on Redundancy Table.

4.

Choose any circuit from the Circuit Name list that appears by doubleclicking on it. A Redundancy Information View window appears.

5.

Set the Retry Count to any value between 1 and 10, inclusive.

6.

For any of the devices other than the IRM-3 enter the Ethernet address of the secondary hub device, which will be polled, in the MAC Address Add field. This field should allow you to enter the address in any of the following formats (where X is any hexadecimal value from 0 to F):

XX.XX.XX.XX.XX.XX

XX:XX:XX:XX:XX:XX

XX-XX-XX-XX-XX-XX

For the IRM-3, enter the IP address of the secondary hub device, which will be polled, in the IP Address Add field. You should enter this address in the format NNN.NNN.NNN.NNN (where NNN is a decimal number from 0 to

255).

7.

Enter the Board Port Instance for the primary connection. For example, if the primary connection is on port 4 of a module in the device’s fifth slot, the Board Port Instance would be 5.4. (Modules on these devices start from 1 and can go up to 8 depending on the MMAC type.)

8.

Change the Port Circuit Status to Active and the Port Circuit Type to

Primary.

9.

Choose Save All Changes from the File menu. This will save the circuit configuration you entered.

10. Now change the Board Port Instance to represent the backup connection.

Change the Port Circuit Status to Inactive and the Port Circuit Type to

Backup.

11. Choose Save All Changes from the File menu. This will save the circuit configuration you entered for the backup connection.

12. Close this Redundancy Information View and then bring it up again.

Verify that the redundancy setup information is present and correct.

13. Click on the Circuit Enable field and choose Enable. This enables the circuit that was created on the primary hub device. Choose Save All

Changes from the File menu.

14. Now physically connect the secondary circuit between the two hub devices. To test the redundancy, disconnect the primary circuit and make sure the backup circuit becomes active.

Event and Alarm Messages

What is in this Chapter

This chapter describes the events and alarms that the Cabletron Ethernet

Hubs Management Module supports. It also notes if an event is mapped to an identical alarm message, and if it provides any corresponding probable cause message.

Events and alarms originate as generic Simple Network Management

Protocol (SNMP) traps sent from the physical hub devices. These traps, or unsolicited messages, are translated as SPECTRUM events and displayed in the Event Log. For more information on specific SNMP traps, refer to RFC

1213 available through the Internet system. Also refer to the Management

Information Base (MIB) documentation for each specific hub 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 braces will be replaced by the named variable followed by a specific value, without the braces.
