The remainder of the window displays the counts for the error type or types you selected when you launched the window.
Ring Map AC Errors The count of frames containing errors in the ARI (Address Recognized Indicator) or FCI (Frame Copied Indicator) bits.
Ring Map buffers. Note that this counter reports the number of times frames were dropped for lack of buffering, not the number of frames dropped. Although this is considered a non-isolating error, you can assume that the adapter reporting the error is at fault. If the error occurs frequently, you may want to consider replacing the reporting station’s NIC card.
Ring Map If the inserted station is connected to another hub (via the monitored hub’s Ring-in/Ring-out ports), the board and port are unknown and will display as zeroes (0,0). The station’s physical drop is an administratively assigned string that you can use to identify a station’s physical location.
Ring Map Figure 3-9. The Device Information Window Setting the Map Poll Interval You can set the poll interval that controls how often the monitored hub is queried for changes in the selected ring’s station list.

Chapter 4 Alarm Configuration Setting Alarms at the Ring and Station levels; Alarm Types defined Alarms work in conjunction with your network management system to let you know when certain defined thresholds have been reached. Using this tool, you define the condition that will trigger an alarm; the device monitors traffic and, when defined thresholds are reached, reports to the network management station in the form of a trap.
Alarm Configuration from the Hub View: 1. Click on the Device button to display the Device menu. 2. Drag down to Alarm Configuration and release. from the command line (stand-alone mode): 1. From the appropriate directory, type spmarun e5alarms NOTES The spmarun script invoked first in the above command temporarily sets the environment variables SPMA needs to operate; be sure to use this command any time you launch an application from the command line.
Alarm Configuration Setting and Viewing Ring Alarms To view or set ring-level alarms, highlight the appropriate interface (network), then click mouse button 1 on ; the Ring Alarms window, Figure 4-2, will appear. Figure 4-2. The Ring Alarms Window The alarm Timebase entered here applies to all enabled alarms at both the ring and station levels; this is the interval (in seconds) over which the selected variable(s) will be counted for comparison to the threshold values.
Alarm Configuration The Alarm Type list displays the variables available for alarms, the current status of each alarm, and the current threshold setting. To change the status or threshold for an alarm, you must first select it in this list. You can set an alarm threshold for the following variables: 4-4 Ring Purges The number of times the active monitor has purged the ring since the network was created, or since the TRMMIM was last reset.
Alarm Configuration The Threshold field allows you to configure a new threshold for the alarm highlighted in the Alarm Type list. NOTE When setting thresholds for ring-level alarms, keep in mind that the TRMMIM is counting all occurrences of the selected variable on the whole ring, not just those occurrences on a single station. Note, too, that ring-level alarms can only be set for nonisolating errors — that is, those that do not pinpoint a specific trouble spot on the ring.
Alarm Configuration NOTE You need not close the Ring Alarms window before launching the Station Alarms window; just move the Ring Alarms window out of the way, if necessary, to reach the main Ring/Stn Alarms window. Figure 4-3.
Alarm Configuration NOTE Alarm conditions which occur over the span of two timebase intervals will not be detected, even if the threshold is crossed within a period of time that is less than or equal to the defined timebase interval. For example, if you set your timebase to 10 seconds and an alarm threshold to 50, an alarm will be generated if 50 of the specified events are detected within a specific 10-second interval defined by the device.
Alarm Configuration AC Errors Also known as ARI/FCI errors, AC errors occur during the Ring Poll or Neighbor Notification process when one station fails to correctly set the ARI (address recognized) and FCI (frame copied) indicator bits on the current AMP (active monitor present) or SMP (standby monitor present) frame intended for it, thus leaving its downstream neighbor without an accurate upstream neighbor’s address.
Alarm Configuration The Status field allows you to enable or disable the selected alarm; this alarm status will be applied as indicated by the current selection in the Set Alarm For field. The Set Alarm For field features a menu button which allows you to apply new alarm status and threshold settings to selected stations only, to all stations on a module, or to all stations on the ring.

Chapter 5 Statistics Using Statistics; Viewing the Ring Station List; Monitoring Ring and Station Statistics, Ring Variables; Station Variables Using Statistics The statistics windows provide you with a variety of information about the ring as a whole and each station inserted into the ring, including traffic counts, total error counts, and error type breakdowns.
Statistics from the command line (stand-alone mode): 1. From the appropriate directory, type: spmarun e5stats NOTES The spmarun script invoked first in the above command temporarily sets the environment 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.
Statistics Figure 5-2. Ring and Station Statistics Window The Ring and Station Statistics window lists each active station on the ring; the following information is provided for each station: MAC Address Displays the station’s MAC or hardware address. MAC addresses are usually factory set and cannot be changed. (The MAC address will be displayed in Token Ring format.) Module and Port Provides the station’s location in the MMAC chassis by module and port number.
Statistics Using the Reverse MAC Button The Reverse MAC button, available in the Ring and Station Statistics window, enables you to toggle between Token Ring and Ethernet MAC address formats. Token Ring MAC addresses (the default address format in this window) are displayed in the reverse bit order of Ethernet MAC addresses. The Ethernet MAC format is the more recognizable format; therefore, the Reverse MAC button can be used to enable the network manager to recognize the MAC addresses more easily.
Statistics If you are running SPMA in conjunction with HP Network Node Manager or IBM NetView you can also customize ring-specific or station-specific graphs using the same variables as are available for the meters. You can graph up to 25 variables in a single graph. NOTE 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.

Statistics If a station receives an AMP or SMP MAC frame with the ARI and FCI bits set to 0 without first receiving an intervening AMP frame it recognizes that its upstream station failed to set the ARI/FCI bits. The receiving station will increment an ARI/FCI set error counter, and end the ring poll process by not transmitting an SMP MAC frame. Since it has not received a valid SMP frame, it does not have a correct NAUN address.
Statistics Lost frames are usually caused by a station entering or leaving the ring as the frame is circulating. Lost frames will cause the active monitor to initiate the ring purge process and issue a new token. Congest A congestion error occurs when a station recognizes a frame addressed to it, but is unable to copy the frame because it has no available buffer space.

Chapter 6 Ring Security Configuration Selecting a ring for which to set security; configuring the Allowed and Disallowed Station Lists; selecting ring security levels About Ring Security The Ring Security application allows you to control access to the Token Ring networks being managed by the TRMMIM by specifying an “Allowed List” of stations permitted to enter the ring, a “Disallowed List” of stations removed from the Allowed List, and a security mode which controls the ring’s response to stations illega
Ring Security Configuration manually (by entering the address of a disallowed station), or by moving an entry from the Allowed List. You can also restore a station from the Disallowed List to the Allowed List, if desired. Once Security has been configured and enabled, the TRMMIM acts as the Ring Security Monitor and provides security for the entire ring. ! CAUTION The Token Ring Security application is intended to be used by a knowledgeable network administrator.
Ring Security Configuration NOTES The spmarun script invoked first in the above command temporarily sets the environment 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 change any Security settings, be sure to use a community name with at least Read/Write access.
Ring Security Configuration Figure 6-2. The Security Config Window The Security Config window is where you actually configure security for the selected ring; it contains the following information: Allowed Station List This list box displays the MAC address of each station in the ring security Allowed List database — that is, those that have security authorization to enter the selected ring. This database is maintained in the TRMMIM itself.
Ring Security Configuration Vendor This field, visible in both list boxes, displays the vendor associated with each list entry, as determined by the first three bytes in its MAC address. Security Mode Options The Security Mode options at the top of the Security Config window display the current security configuration, and allow you to reconfigure security.
Ring Security Configuration Allowed/Disallowed List Configuration Buttons The following buttons are used to manipulate the Allowed and Disallowed Lists and to set the security mode at the device: This button moves a selected address(es) from the Allowed List to the Disallowed List.
Ring Security Configuration duplication exist between the lists, the duplicate entries will be removed from the Disallowed List. There will not be any alert if this occurs. Selecting this button closes the Security Config window. Any sets you have made in the window before closing will have taken effect. Configuring Security Before configuring security, be sure that your network meets the requirements and conditions specified in your TRMMIM’s hardware Installation and User’s Guide.
Ring Security Configuration Figure 6-3. The Station Addition Window 2. Enter the MAC address of the station you want to add to the Allowed or Disallowed Stations List, as follows: a. In the MAC Address field, type the address in XX-XX-XX-XX-XX-XX hexadecimal format. b. Using the buttons at the bottom of the window, select the Allowed or Disallowed List option, as appropriate. c. Click on to enter the new stations in the appropriate list, then to exit the window.
Ring Security Configuration Moving a Station Between the Allowed and Disallowed Stations List You can move an individual station or a range of stations between the Allowed and Disallowed Stations Lists, as follows: 1. Click mouse button 1 on an individual station in the appropriate list, or click and drag to select a range of stations you want to switch to the opposite list. A station will be highlighted to show it is selected. 2.
Ring Security Configuration Changing the Ring Security Mode Use the Enable Security and Disable Security options at the top of the Security Config window turn security on and off; use the Security Mode options to select the level of security you wish to activate: Disable Security Selecting this option disables ring security so that any station can attempt to enter the ring.
Appendix A TRMMIM MIB Structure TRMMIM management information base configuration IETF MIB Support In addition to its proprietary features, the TRMMIM currently supports the following IETF MIBs: • RFC 1213 MIB for Network Management of TCP/IP-based Internets: MIB-II • RFC 1271 Remote Network Monitoring MIB • RFC 1757 Token Ring Extensions to RMON TRMMIM MIB Structure Cabletron’s newer intelligent devices — like the TRMMIM — organize MIB data into a series of “components.
TRMMIM MIB Structure The TRMMIM MIB consists of the following components: Chassis MGR The Chassis MGR MIB component contains most of the basic information about the TRMMIM, the chassis it is controlling, and the other modules installed in that chassis, including: chassis type, backplane type, number of slots, which module types and names are installed in which slots, the TRMMIM’s MIB component information (in the chCompTable), device and module names, hardware revision numbers, MAC and IP addresses, the cu
TRMMIM MIB Structure RMON The RMON, or Remote Network Monitoring, MIB component contains the statistics, history, alarm, event, and Token Ring groups from the RMON MIB (RFC 1271 and 1757). Telnet The Telnet component provides a means by which you can remotely access the TRMMIM’s Local Management screens, including MIB Navigator — a command set from which you can configure and manage your TRMMIM by viewing and modifying the objects in the device’s MIB.
TRMMIM MIB Structure the original component-based MIB architecture, this means you must use the exact community name you have assigned to a specific component to access that component’s MIB information. (Again, note that the TRMMIM’s Network components always have unique community names.
