Device View

This section describes the Device view and subviews available for models of Cabletron Ethernet Hubs in

SPECTRUM.

Access: From the Icon Subviews menu for the Device icon, select Device > Logical or Device > Physical.

This view 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 view provides dynamic configuration and performance information for each of the device’s serial and network I/O ports, which are represented by

Interface icons in the bottom panel of the view.

Performance Views

This section provides brief descriptions of the Performance views available for the Cabletron ethernet hubs in

SPECTRUM.

Performance views display performance statistics in terms of a set of transmission attributes, e.g., cell rates, frame rates, % error, etc. A typical view is shown in

Figure 8 . The instantaneous

condition of each transmission attribute is recorded in a graph. The statistical information for each attribute is presented in the adjacent table.

Generally, you determine performance at the device level through Performance views accessed from the Device and Application icons. You determine performance at the port/interface level through Performance views accessed from

Interface icons.

For more information on Performance views, refer to the SPECTRUM Views documentation.

The following paragraphs list the performance attributes displayed for each Performance view supported by this management module.

Hub Redundancy Management

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

• IRM2

• IRM3

C a b l e t r o n E t h e r n e t H u b s

C o n f i g u r a t i o n V i e w s

• MRXI

• MiniMMAC

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

H u b R e d u n d a n c y M a n a g e m e n t

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 10 (Page 65) for an illustration of a typical

redundant cable circuit connection between two redundant hub devices.

Primary Active Circuit

Page 65

S e t t i n g R e d u n d a n t C i r c u i t s

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 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

C a b l e t r o n E t h e r n e t H u b s

C o n f i g u r a t i o n V i e w s 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.

S P E C T R U M E n t e r p r i s e M a n a g e r Page 66

S e t t i n g R e d u n d a n t C i r c u i t s

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.

C a b l e t r o n E t h e r n e t H u b s

C o n f i g u r a t i o n V i e w s

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

Click on the icon to select it.

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

From the Configuration View menu, click on

5

Choose any circuit from the Circuit Name list that appears by double-clicking on it. A

Redundancy Information View window appears.

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

S e t t i n g R e d u n d a n t C i r c u i t s

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.)

This will save the circuit configuration you entered.

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