Chapter 1 Introduction How to use this guide; related guides; software conventions; getting help; MicroMMAC-T firmware versions Welcome to the NetSight Element Manager for the MicroMMAC-T User’s Guide. We have designed this guide to serve as a simple reference for using NetSight Element Manager for the MicroMMAC-22T/24T and MicroMMAC-42T/44T.
Introduction NetSight Element Manager provides remote management for the MicroMMAC-T, including: • Front panel status display with administrative state, network load, and error percentages available for each port. • Management Station Configuration. • Station List and Map Windows. • Full statistics display for the hub and individual stations (with both numerical and graphical display options). • Alarm Limits based on frame counts, frame errors, or beacon frames.
Introduction We assume that you have a general working knowledge of Token Ring IEEE 802.5 type data communications networks and their physical layer components. Related Manuals The MicroMMAC-T user’s guide is only part of a complete document set designed to provide comprehensive information about the features available to you through NetSight Element Manager.
Introduction Left Mouse Button Right Mouse Button Figure 1-1. Mouse Buttons For many mouse operations, this document assumes that the left (primary) mouse button is to be used, and references to activating a menu or button will not include instructions about which mouse button to use. However, in instances in which right (secondary) mouse button functionality is available, instructions will explicitly refer to right mouse button usage.
Introduction Using Window Buttons The button that appears at the bottom of most windows allows you to exit a window and terminate any unsaved changes you have made. You may also have to use this button to close a window after you have made any necessary changes and set them by clicking on an , , or button. An , , or button appears in windows that have configurable values; it allows you to confirm and SET changes you have made to those values.

Chapter 3 Token Ring Statistics Using Statistics window features; monitoring ring-level statistics, timer statistics, and performance graphs; monitoring management station statistics; monitoring port-level statistics, timer statistics, and performance graphs NetSight Element Manager provides valuable performance statistics from the Network, Management Station, and Port levels.
Token Ring Statistics Using these radio buttons, you can choose whether to view the statistics gathered since the MicroMMAC-T was last restarted or (if you are monitoring port-level statistics) since the station was first inserted (Total), during the last polling interval (Delta), or accumulated from zero at a user-defined point (Cumulative).
Token Ring Statistics • Peak (Magenta) — Indicates the maximum level of activity over all time intervals since the window was invoked. Statistics displayed in the color-coded strip charts will automatically update within the time interval you have set using the clock symbol at the bottom of the window (See Setting the Statistics Poll Interval, below, for details on using the clock symbol).
Token Ring Statistics 4. Click on OK. The new Time Interval will take effect for the current instance of the window in which you have set it. Remember, the poll interval returns to its default value each time you close, and then re-open a statistics window. Network Level Statistics Using the Network pull-down menu, you can view performance statistics for the MicroMMAC-T-managed ring. The MicroMMAC-T-managed ring is represented by the Network 1 entry in the Network pull-down menu.
Token Ring Statistics Ring Speed The operating speed (4 Mbit/sec or 16 Mbit/sec) of the current ring. Figure 3-4. The Network Statistics Window By using the radio buttons located at the bottom of the Network Statistics window, you can choose whether to view the statistics gathered since the MicroMMAC-T was last started up (Total), counted during the last polling interval (Delta), or accumulated from zero at a user-defined point (Cumulative).
Token Ring Statistics Ring Purges Displays the number of times the active monitor has purged the ring since the network was created, or since the MicroMMAC-T was last reset. This includes the purge at the end of the active monitor selection process. The count is not reset when the active monitor changes. Total Frames Displays the number of frames that have been transmitted on the ring. Total KBytes Displays the total number of kilobytes that have been transmitted on the ring.
Token Ring Statistics The first station detecting the data corruption sets the E bit to 1 in the ending delimiter of the frame and logs the error. This prevents other stations from logging the error and isolates the portion of the line which is causing the data corruption. Burst Errors Displays the total number of burst errors detected on the ring. These errors occur when a station does not clock an incoming data signal correctly.
Token Ring Statistics Lost Frames Displays the number of lost frame errors detected on the ring. These occur when a station is transmitting and its TRR (Timer, Return to Repeat) timer expires. This timer ensures that the station returns to the data repeat state. Lost frames are usually caused by a station entering or leaving the ring as the frame is circulating – since this often throws the ring temporarily out of synchronization.
Token Ring Statistics Total Errors The sum of all errors currently recorded. Network Timer Statistics You can use the Network Timer Statistics window (Figure 3-5) to view the number of frames, errors, and bytes processed by the ring over a user-defined time interval (allowable time settings are 1 second to 23 hours, 59 minutes, 59 seconds). This allows you to quickly scan the display to obtain information concerning the network activity. Figure 3-5.
Token Ring Statistics Frames Displays the elapsed, average, and peak levels of good frames transmitted on the network. Errors Displays the elapsed, average, and peak levels of errors received by the network. KBytes Displays the elapsed, average, and peak levels of kilobytes processed by the network. Network Performance Graphs The Network Performance Graphs (Figure 3-6) provide real-time statistics reporting. The color-coded strip charts allow you to visually track the performance of the entire network.
Token Ring Statistics Network Performance Graph Statistics The Network Performance Graph contains the following statistics: Network Events (Red) Total Errors The total number of soft errors of any kind processed by the network. Ring Purges The total number of times the ring’s active monitor has issued a ring purge command. Beacon States The number of beacon states on the ring which have been corrected by the automatic beacon recovery process (ABRP).
Token Ring Statistics The Frame Size Window At the Frame Size window, Figure 3-7, you can see the actual sizes of the frames on the ring network controlled by your MicroMMAC-T. The frame sizes and corresponding colors are: • • • • • • • • <<64 (Red) 64-127 (Green) 128-255 (Rose) 256-511 (Yellow) 512-1023 (Gray) 1024-2047 (Cyan) 2048-4095 (Magenta) >>4095 (Orange) Figure 3-7. The Device Frame Sizes Window These frame size statistics are presented in numerical, bar graph, and pie chart form.
Token Ring Statistics • Click on the Total radio button. The numbers to the left of the selected graph (in the color-coded boxes) display the total count of frame sizes processed since the most recent start-up of the MicroMMAC-T. The dynamic bar graph or pie chart to the right of the numbers reflects counts processed since the last start-up.
Token Ring Statistics The Protocol Statistics Window At the Protocol Statistics window (Figure 3-9) you can see how many frames are received by the MicroMMAC-T for a given protocol. Figure 3-9.
Token Ring Statistics • Click on the Total radio button. The window will now display the total count of protocol types processed since the most recent start-up of the MicroMMAC-T. The dynamic bar graph or pie chart to the right of the numbers reflects counts processed since the last start-up. Using the Pie and Bar Radio Buttons You can use the Pie and Bar radio buttons to switch from bar graph to pie chart.
Token Ring Statistics Figure 3-10. The TR Management Station Statistics Window This window also lists both soft and hard error conditions detected by the MicroMMAC-T’s management station, as explained in the following sections. The Total Errors field indicates the sum of both soft and hard errors that the management station has detected.
Token Ring Statistics A.C. Errors The count detected by the management station of frames (Protocol Data Units or PDUs) containing errors in the A or C bits. Abort Sequences The management station’s count of abort sequences detected on the ring, which were issued by ring stations during transmission. Internal Errors The number of recoverable internal errors detected by the management station, indicating a ring station in marginal operating condition.
Token Ring Statistics Transmitted Beacons Beacon frames are transmitted by ring stations when certain error conditions are detected. These frames notify all ring stations that there is a problem, and causes the stations in the fault domain (the beaconing station and its NAUN) to remove themselves from the ring and perform a loopback test. If either station fails the test, its removal should allow the ring to recover. Recoveries Indicates that claim tokens have been detected on the ring.
Token Ring Statistics Port Level Statistics Through the Station Port pull-down menu, you can view statistics for a station inserted into a ring, and graphically monitor the selected station via Timer Statistics and the Performance Graph. The following sections detail how to access the Station Port pull-down menu, and how to use the menu to view numerical and graphical statistics for a station port.
Token Ring Statistics Figure 3-11. The Station Statistics Window The Station Statistics Window General Fields The Station Statistics window contains the following fields: Station Name Use this editable field to assign a name to the station attached to the selected port.
