Using the TRMMIM User’s Guide

Your SPECTRUM Portable Management Application (SPMA) for the TRMMIM consists of a number of different applications, each of which provides a portion of the overall management functionality. Each of these applications can be accessed from the icon menu (if you are using a management platform), from the Hub View (which is a graphical display of the TRMMIM-managed hub), and from the command line (if you are running in stand-alone mode).

The TRMMIM User’s Guide describes how to use many of the applications included with the module; note that the instructions provided in this guide apply to the TRMMIM module regardless of the operating system or management platform you are using. Instructions for launching each individual function from the command line (stand-alone mode) are also included in each chapter.

™

or the

Following are descriptions of the applications detailed in this guide; while we provide as much background information as we can, we do assume that you’re familiar with Token Ring networks and general network management concepts.

1-1

Introduction to SPMA for the TRMMIM

• Chapter 1, Introduction , describes the TRMMIM User’s Guide and the conventions used in this and other SPMA manuals, explains where to ﬁnd information about the TRMMIM, and tells you how to contact Cabletron Systems Technical Support.

• Chapter 2, Using the TRMMIM Hub View , describes the visual display of the Hub and explains how to use the mouse within the Hub View. Also described are some basic functions available only from within the Hub View (changing the Hub View display, opening menus and windows, enabling and disabling ports, checking device and module status, and so on).

• Chapter 3, Ring Map , describes how to graphically display all stations inserted into your TRMMIM-managed Token Ring network. Using the Ring Map application, you can display stations and perform station searches according to various parameters, view and compare errors detected on the ring, conﬁgure the ring management station, set station drops or station names, view summary information about station conﬁguration and ring performance, view ring history information, and launch other SPMA Token Ring applications.

• Chapter 4, Alarm Conﬁguration , describes how to set thresholds and enable or disable alarms at the ring and station levels.

• Chapter 5, Statistics , describes how to use the statistics windows to view ring and station-speciﬁc information, including trafﬁc counts, total error counts, and error type breakdowns.

• Chapter 6, Ring Security Conﬁguration , describes how to remotely conﬁgure security for the TRMMIM. The Ring Security application allows you to control access to your TRMMIM-managed Token Ring network, and specify a security mode for stations illegally attempting to enter the ring.

• Appendix A, TRMMIM MIB Structure , lists the individual components that collectively compose the TRMMIM’s MIB.

What’s NOT in the TRMMIM Guide...

The following standard SPMA tools are available through the TRMMIM module and are explained in the SPECTRUM Portable Management Application Tools

Guide :

• Charts, Graphs, and Meters

• Community Names

• Global Find MAC Address Tool

• MIBTree

• MIB I, II

• Telnet

NOTE

Introduction to SPMA for the TRMMIM

• TFTP Download

• Trap Table

The Charts, Graphs, and Meters application is accessible from the Hub View and the command line; the Global Find MAC Address Tool is accessible from the platform console window Tools menu; the MIBTree application is accessible from the platform console window Tools menu, the Stand-alone Launcher window, and the command line; the Telnet application is available from the command line; the rest of the tool applications are available only from the icon menu or the command line.

Graphing capabilities are provided by an application that is included in HP Network Node Manager and IBM NetView; therefore, graphs are only available when SPMA is run in conjunction with one of these network management platforms. If you are running SPMA in a stand-alone mode or in conjunction with SunNet Manager, no graphing capabilities are available and no graph-related options will be displayed on buttons or menus. Note that the screens displayed in this guide will include the graph-related options where they are available; please disregard these references if they do not apply.

Instructions on discovering Cabletron devices, creating icons, and accessing the icon menus within your management platform are included in your Installing

and Using SPECTRUM for... guide. If you are using SPMA for the TRMMIM in

stand-alone mode (without beneﬁt of a speciﬁc network management system), instructions for starting each application from the command line are included in each chapter, both in this guide and in the SPMA Tools Guide .

Conventions

The family of SPECTRUM Portable Management Applications can work with a number of different network management systems running on several different operating systems and graphical user interfaces. This versatility presents two documentation problems: ﬁrst, there is no standard terminology; and second, the appearance of the windows will differ based on the graphical interface in use. For the sake of consistency, the following conventions will be followed throughout this and other SPMA guides.

Screen Displays

SPMA runs under a variety of different operating systems and graphical user interfaces. To maintain a consistent presentation, screen displays in this and other SPMA guides show an OSF/Motif environment. If you’re used to a different GUI, don’t worry; the differences are minor. Buttons, boxes, borders, and menus displayed on your screen may look a bit different from what you see in the guide, but they’re organized and labelled the same, located in the same places, and perform the same functions in all screen environments.

Conventions 1-3

Introduction to SPMA for the TRMMIM

Some windows within SPMA applications can be re-sized; those windows will display the standard window resizing handles employed by your windowing system. Re-sizing a window doesn’t re-size the information in the window; it just changes the amount of information that can be displayed (see Figure 1-1). When you shrink a window, scroll bars will appear as necessary so that you can scroll to view all the information that is available.

Use the scroll bars provided to choose what to display in a window that’s been resized

Click here to display footer message history

Figure 1-1. Window Conventions

Some windows will also contain a button; selecting this button launches a History window (Figure 1-2) which lists all footer messages that have been displayed since the window was ﬁrst invoked. This window can help you keep track of management actions you have taken since launching a management application.

1-4 Conventions

Introduction to SPMA for the TRMMIM

Using the Mouse

The UNIX mouse has three buttons. Procedures within the SPMA document set refer to these buttons as follows:

Figure 1-2. The History Window

Button 1

Button 2

Button 3

Figure 1-3. Mouse Buttons

If you’re using a two-button mouse, don’t worry. SPMA doesn’t make use of mouse button 2. Just click the left button for button 1 and the right mouse button when instructed to use mouse button 3.

Conventions 1-5

Introduction to SPMA for the TRMMIM

Whenever possible, we will instruct you on which mouse button to employ; however, menu buttons within SPMA applications will operate according to the convention employed by the active windowing system. By convention, menu buttons under the Motif windowing environment are activated by clicking the left mouse button (referred to as mouse button 1 in SPMA documentation), and there is no response to clicking the right button (mouse button 3). Under OpenWindows, menu buttons can be activated by clicking the right button, and convention dictates that the left button activates a default menu option; within SPMA, that default option will also display the entire menu. Because of this difference, references to activating a menu button will not include instructions about which mouse button to use. All other panels from which menus can be accessed, and all buttons which do not provide access to menus, will operate according to SPMA convention, as documented.

Using the TRMMIM Hub View

Navigating through the Hub View, monitoring hub activity; managing the hub at the device, module, and port levels

The heart of the SPECTRUM Portable Management Application (SPMA) for the TRMMIM is the Hub View, a graphical interface that gives you access to many of the functions that provide control over the TRMMIM-managed hub.

Note that the Hub View application only allows you to control boards and ports in the

NOTE

domain of a single management module. If you have another management module installed in the chassis to the left of the monitored TRMMIM, boards that are under the domain of that module (i.e., Media Interface Modules – or MIMs – to its left) will still display in the Hub View of the monitored TRMMIM; however, only boards within the domain of the monitored TRMMIM can be correctly controlled. Flexible Network Bus (FNB) connections across the MMAC chassis will be displayed regardless of modules installed; however, only FNB connections within the domain of the monitored module can be controlled. For example, if you had a TRMMIM and a TRBMIM installed in the same chassis with the TRBMIM to the left of the TRMMIM, and you were modeling the TRMMIM in a Hub View, you would have to create a separate Hub View for the TRBMIM to control the FNB connections and manage MIMs to the left of the TRBMIM. However, even while modeling the TRMMIM, you would still be able to view the boards and FNB connections across the entire MMAC.

Using the Hub View

There are two ways to open the Hub View: if you are working within a network management system, you can select the Hub View option from the icon menu; speciﬁc directions for creating a TRMMIM icon and accessing the icon menu can be found in the appropriate Installing and Using SPECTRUM for... guide. If you are running the TRMMIM module in a stand-alone mode, type the following at the command line:

spmarun e5hub <IP address> <community name>

2-1

Using the TRMMIM Hub View

The community name you use to start the module must have at least Read access; for full management functionality, you should use a community name that provides Read/Write or Superuser access. For more information on community names, consult the appropriate Installing and Using SPECTRUM for... guide, and/or the Community Names chapter in the SPMA Tools Guide.

The spmarun script invoked ﬁrst in the above command temporarily sets the environment

NOTES

variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line. This script is automatically invoked when you launch an application from the icon menu or from within the Hub View.

If you wish to conﬁgure your Token Ring hub in any way, be sure to use a community name with at least Read/Write access. If you only wish to view current settings, a community name with Read access will be sufﬁcient.

If there is a hostname mapped to your TRMMIM’s IP address, you can use <hostname> in place of <IP address> to launch this application. Please note, however, that the hostname is not the same as the device name which can be assigned via Local Management and/or SPMA; you cannot use the device name in place of the IP address.

Navigating Through the Hub View

Within the Hub View (Figure 2-1), you can click mouse buttons in different areas of the window to access various menus and initiate certain management tasks. The following describes the information displayed in the Hub View and shows you how to use the mouse to display the Device, Module, and Port menus.

2-2 Using the Hub View

Using the TRMMIM Hub View

Hub View Front Panel

In addition to the graphical display of the Media Interface Modules (MIMs), the Hub View gives you device-level summary information. The following Front Panel information appears to the right of the module display in the Hub View:

Contact Status is a color code that shows the status of the connection between SPMA and the device:

• Green indicates a valid connection.

• Blue means that SPMA is trying to reach the device but doesn’t know yet if the

connection will be successful.

• Red means that SPMA is unable to contact or has lost contact with the device.

Using the TRMMIM Hub View

Graphing capabilities are provided by an application that is included in HP Network

NOTE

Node Manager and IBM NetView; therefore, graphs are only available when SPMA is run in conjunction with one of these network management platforms. If you are running SPMA in a stand-alone mode or in conjunction with SunNet Manager, no graphing capabilities are available and no graph-related options will be displayed on buttons or menus. Note that the screens displayed in this guide will include the graph-related options where they are available; please disregard these references if they do not apply.

• Launch the Security application, so that you can establish safeguards against unauthorized stations attempting to insert into the ring. This application is described thoroughly in the Ring Security Conﬁguration chapter.

The IP Address Table option in the Device menu (shown in Figure 2-2, grayed out) is not supported for the TRMMIM.

Using the TRMMIM Hub View

Hub View Port Color Codes

The Port Status boxes on each MIM in the Hub View are color-coded to indicate the port’s connection status. There are two color-coding schemes: one which is associated with port Admin/Link status, and another associated with port Admin status (these modes are described in the Port Display Form section, following). The default color scheme is the one which indicates port Admin/Link status; that is, for any Port Display Form except port Admin status, the colors will indicate the status conditions described below.

• Green indicates that the port is active; that is, the port has been enabled by management, has a valid Link signal (if applicable), and is able to communicate with the station at the other end of the port’s cable segment.

• Blue indicates that the port has been disabled or bypassed through management.

• Yellow indicates that the port is enabled but does not have a valid connection. This usually indicates that the device at the other end of the segment is turned off, or that there is no cable attached to that port; stations which remove themselves from the ring for self-testing will also display as yellow.

When Admin is the selected Port Display Form, there are only two status conditions and colors:

• Green indicates that the port is enabled. This does not indicate whether or not there is any cable connected to the port, or whether communication has been established with the device at the other end of an attached cable.

• Blue indicates the port has been disabled or bypassed through management.

If an intelligent MIM (e.g., the TRBMIM) is inserted in the MMAC chassis to the left of

NOTE

the TRMMIM, its module status box will be colored purple and labeled “Special” for clear identiﬁcation. To manage another intelligent MIM (and any boards in its domain), a separate Hub View must be created for it. For example, if you had a TRMMIM and a TRBMIM installed in the same chassis, with the TRBMIM to the left of the TRMMIM, and you were modeling the TRMMIM in a Hub View (the TRBMIM would bear the “Special” module status box mentioned above), you would have to create a separate Hub View for the TRBMIM in order to control the FNB connections and manage MIM ports to its left. However, even while modeling the TRMMIM, you would still be able to view the boards and FNB connections across the entire MMAC.

Port Display Form

You can change the type of information displayed for each port in the hub by using the Port Display Form option on the Device menu. Changing the port display form via the Device menu will affect all manageable ports in the hub.

To change the port display form:

Port display form options are:

Frames

Shows the total number of frames transmitted by the port, in a frames/second format.

Total Bytes

Shows the total number of bytes transmitted by the port, in a bytes/second format.

Errors

Shows port trafﬁc errors as a rate (errors/second). You can display any one of the following types of errors:

• Total errors

• Isolating errors

• Non-isolating errors

• Line errors

• Burst errors

• AC errors

• Abort Sequence errors

• Internal errors

• Lost Frame errors

• Rx Congestion errors

• Frame Copied errors

• Token errors

• Frequency errors

For error type descriptions, see Checking Statistics, page 2-22.

When a device is reset, statistics windows and/or statistics displays in the Hub View may

display very large numbers for one polling interval. This is due to the resetting of the counters.

Port T ype

Provides the following administrative information about the port:

• Admin/Link Status indicates the Administrative and Link connection status

of the ports:

- ENB (Enabled) indicates that the port has been enabled by management, but there is no station linked to the port.

- BYP (Bypassed) indicates the port has been disabled by management.

- ACT indicates a ring port is active and passing data.

- WRAP indicates data communications have been terminated at the ring

• Admin Status displays either ON or OFF, an indication of whether management has the port enabled or disabled. A port can be ON but not operational. Under the Admin display, ports that are enabled but not linked are shown as ON.

• Media Type applies only to selectable-media ring ports and indicates the type of cabling supported by the port:

NOTE

- Ring ports that do not have media selection will display “---”.

- Station ports will display “---”.

• Active Ports displays the following information about statistics for the port:

-Yes if a linked (green with INS Admin/Link status) port on the

TRMMIM-managed ring has recorded statistics since the statistical counters were last reset.

-No if a linked (green with INS Admin/Link status) port on the

TRMMIM-managed ring has not recorded statistics since the statistical counters were last reset.

- “---” for non-TRMMIM-managed ports (i.e., ports that are not

on the managed ring), regardless of their status.

The FNB Display option is meant for use with multi-Token Ring management modules (e.g., the TRMM-2 and TRMM-4) and port switching MIMs (e.g., the TRXMIM and TDRMIM) in order to view the FNB connection status of the port switching MIMs. Since the TRMMIM is a single-Token Ring management module, only the FNB 1 display selection (which is the default display for your Hub View) is applicable.

2-10 Using the Hub View

Using the TRMMIM Hub View

Using the FNB Display option from the Device menu, you can change the FNB index (see Figure 2-4 ) for all boards in the Hub View. By default, all boards in the Hub View initially display FNB 1. When you change the FNB Display, the Hub View will change to show each board’s relationship with the selected FNB. Hub View features that will change include:

• The FNB index, which will display the index for the selected FNB.

• The FNB Bypass State, which will change to show the bypass state (INS, BYP,

or ---) for each module with respect to the selected FNB. If FNB 2, 3, or 4 are selected, non-port switching modules in the chassis will display ---, indicating that no connection is possible with the selected FNB. To change the FNB Bypass State, see Controlling Token Ring FNB Multiplexer Connections, on

page 2-28.

• The FNB Status/Control symbols, which will display each module’s

relationship with its neighbors with respect to the selected FNB. If FNB 2, 3, or 4 are selected, no FNB Status/Control symbols will be present for non-port switching modules in the chassis. For information on manipulating the FNB Status/Control symbols, see Controlling Token Ring FNB

Multiplexer Connections, on page 2-28.

To change the FNB display for all boards in the Hub View:

1. Click on to display the Device menu.

2. Drag down to FNB Display, then right to select FNB 1, 2, 3, or 4.

Monitoring Hub Performance

The information displayed in the Hub View can give you a quick summary of a device’s activity, status, and conﬁguration. SPMA can also provide further details via its four-level menu structure. The Device, Module, Station Port, and Ring Port menus (Figure 2-5, below) give you control over the hub at these four levels and give you access to the tools, menus, and windows which let you monitor speciﬁc aspects of hub performance, change hub display options, and set TRMMIM operating and notiﬁcation parameters. Some of the same functions are available at all four levels; keep in mind, however, that functions accessed from the device menu will provide information about and control all the modules in a hub or in the ﬁrst ring detected by the management board, while the functions accessed from the module or port menus provide information about and control a single module or port.

Using the TRMMIM Hub View

Figure 2-5. The Device, Module, Station Port, and Ring Port Menus

NOTE

Note that the Hub View application only allows you to control boards in the domain of a single management module. If you have another management module installed in the chassis to the left of the monitored TRMMIM, boards that are under the domain of that module (i.e., Media Interface Modules – or MIMs – to its left) will still display in the Hub View of the monitored TRMMIM; however, only boards within the domain of the monitored TRMMIM can be correctly controlled. Although you can display Module menus for MIMs outside of the domain of the monitored TRMMIM, you cannot use these menus to correctly control those MIMs.

Hub performance data available through these menus includes:

• Device, Module, Port, Station, and Ring Port Status windows.

Note that information displayed in the Status windows is static; that is, it is only gathered at the instant the Device, Module, Port, Station, or Ring Port Status window is opened. To receive updated information in one of these windows, you must exit the window and re-open it.

• Device and Station statistics, which provide a complete breakdown of ring activity.

• Device pie-charts, graphs, and meters, as graphic representations of the types and levels of trafﬁc passing through the hub. (For more information about pie charts, graphs, and meters, see the Charts, Graphs, and Meters chapter in the SPMA Tools Guide.)
