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

The SIRM and the IRBM hub devices do not have redundant circuit

NOTE

compatibility available in their device ﬁrmware.

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

9030367 E7 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

9030367 E7 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.

Conﬁguration Views Cabletron Ethernet Hubs 4-24 Management Module Guide

Hub Redundancy Management

Setting Redundant Circuits

4. Choose any circuit from the Circuit Name list that appears by double-

clicking 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.
