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.
Chapter 2

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.

Logical MIM Representation

Logical Gauges
This button allows you to change the statistics represented in the horizontal gauges for the entire MMAC. When you single-click on the Logical Gauges button, a menu appears. The horizontal bar gauge changes color depending on the statistic being represented. The following table provides a list of the menu options and their corresponding gauge color definitions.
Menu Option Gauge Color Definition
Frame Light blue Indicates the number of frames received or
Collisions Yellow Indicates the total number of collisions
transmitted by the module or port.
detected by the module or port.
Gauge Mode
The Gauge Mode button allows you to change the gauge representation of the selected statistic. Refer to Table 4-2 for the statistic gauge representations.
Logical MIM Representation
The logical MIM representation provides information about the individual modules. For information on the Device View physical MIM representation, see the section titled “Physical MIM Representation.”
The logical MIM representation provides port status labels and double-click zones that provide access to information on each module installed in the hub. The logical MIM representation also provides several double-click zones that function as follows:
Port Number
Indicates the port number. You can double-click on the port number to bring up a notes window.
Port Status
Indicates the status of the port. You can double-click on this zone to bring up the Port Performance view, which is described in Chapter 6. When you have accessed the Logical MIM representation through the Physical MIM representation, double-clicking the Port Status Label opens the Port Administration Status dialog box. If you have write privileges, you can double­click on this zone to change the port administration status from ON to OFF or from OFF to ON. Table 2-3 provides the port status values.

Port Performance
Indicates the frame rate for the port. You can change this display using the Gauge Control Panel, which is described later in this chapter. When you have accessed the Logical MIM representation through the Physical MIM representation, the Port Performance label displays a gauge. The rates or percentages measured by this gauge depend on the setting of the Logical Gauges and Gauge Mode buttons. You can double-click on the Port Performance Gauge to bring up the port performance view, which is described in Chapter6.

NOTE
You can also access several generic views from the View and Device Menu pulldown menus. These generic views include:
• Configuration View
• Performance View
• Diagnostic View
• Application View
• Display Logical/Physical MIMs
The procedures for displaying these generic views are given in the section titled “Changing MIM Representations” later in this chapter.
Figures 2-4 through 2-6 show some examples of Device Views for Cabletron hubs. The examples show one or more modules displayed in a Logical Representation.
Some modules may not support logical MIM representations. Refer to the specific module’s hardware documentation.
