Resumen del manual
-On a module without selectable ring ports, the ring ports will display “UNS”. - 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. FNB Display NOTE 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. Monitoring Hub Performance 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 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.) Monitoring Hub Performance Using the TRMMIM Hub View NOTE Graph...
