16 Traps, Events, and Alarms This section describes standard and device-specific events and alarms supported by the (SM-NTL1005) management module. Standard Trap Support Device-Specific Trap Support Standard Trap Support The following standard traps are supported. Standard Trap Name OID coldstart 0.0 warmstart 1.0 linkdown 2.0 linkup 3.0 authenticationfailure 4.0 Device-Specific Trap Support The Nortel Passport 7400 series management module supports the devicespecific traps listed in Table 13 [page 17]. All of these traps contain the variable bindings listed in Table 14 [page 17]. Alarms generated by Nortel Passport traps are discriminated by the variable bindings shown as Alarm Discriminators in Table 14 [page 17]. This means that when successive Nortel Passport 7400 traps of the same type are received by SPECTRUM with the same discriminators as the initial trap, no new alarms will be generated for those traps. Additionally, alarms will be cleared when the alarm-clearing trap contains the same variable bindings as the initial trap that set the alarm. Page 16

18 Application Support This section describes the applications supported by the Nortel Passport 7400 series management module. In This Section RFC and IEEE Standard Applications [page 18] Passport ATM Client Application [page 18] RFC and IEEE Standard Applications The Nortel Passport 7400 series management module has the ability to support various RFC and IEEE standard applications. The applications are created and associated with the device model based on the specific device s capabilities. The following guides contain complete documentation for each of the standard applications supported by SPECTRUM: Bridging Applications (2562) MIB II Applications (2561) Routing Applications (3080) Technology Applications (5065) Transmission Applications (5064) Passport ATM Client Application The Passport ATM Client Application supports Nortel s ATM MIBs (see Table 4: Nortel ATM MIBs [page 11]) and is modeled using the PpATMClientApp application model type. Views available from this application allow you to examine various MIB objects that will assist you in managing the ATM connectivity of the Nortel Passport 7400 series switch. Additional ATM support is available if SPECTRUM s ATM Circuit Manager is installed. See Advanced Application Integrations [page 21] for more information. Page 18

19 Virtual Channel Link View Note: From the PpATMClientApp, select VCL Table. This view displays the status of the VCL links operating on the switch. The data in this view is retrieved from the Nortel ATM MIBs supported by the device. Figure 2: Virtual Channel Link View Page 19

20 Views This section describes device-specific MIB views for the that are accessible from the Icon Subviews menu of the Device icon. In This Section Shelf Card Table View [page 20] Shelf Card Table View Note: From the icon subviews menu for the device icon, select Shelf Card. This view shows objects from the mscshelfcardrowstatustable of Nortel s PpBaseShelfMIB. These objects describe the card components present in each physical card slot within the card shelf. Figure 3: Shelf Card Table View Page 20

21 Advanced Application Integrations This section describes the ATM and Frame Relay integrations that are available for this management module. In This Section ATM Integration [page 21] Frame Relay Integration [page 23] ATM Integration The Nortel Passport 7400 series ATM integration is available when a SPECTRUM installation includes the Nortel Passport 7400 series management module and SPECTRUM s ATM Circuit Manager. This integration uses Nortel-specific model types to effectively model and manage Nortel Passport 7400 Switches that operate in an ATM environment. These model types are used to represent ATM virtual connection endpoints. The interfaces are shown in SPECTRUM stacked in the following order: PpATMIFPort PpATMVCLLink or PpATMVPLLink PpATMMpeAcPort PpATMMpeIfPort The views available from the model types are standard, but the MIB objects displayed are from the proprietary Nortel ATM MIBs (see Table 4: Nortel ATM MIBs [page 11]). Details about each model type are outlined in the sections below: PpATMIFPort Model Type This is the model type that represents a physical ATM port on the Nortel switch. Page 21

22 PpATMVCLLink and PpATMVPLLink Model Types PpATMVCLLink and PpATMVPLLink are sub-interface model types which represent the endpoint of an ATM virtual connection on a Nortel Passport 7400 switch. Below is a description of the ATM-specific subviews available from the Icon Subviews menu for this model type. Model Information This option opens the ATM Link Information view, which allows you to set polling and logging information for the ATM link model. It is possible to configure SPECTRUM to poll link models at regular intervals. When SPECTRUM polls these links it captures the values of various external MIB objects. You can choose to log these values and use them for monitoring and analyzing performance. ATM Circuit View This option brings up a graphical representation of the circuit that connects to the current link. It shows: The path of all of the VCLs that make up a particular ATM PVC. The relationship between the VCL and the sub-interface, the subinterface and interface, and the interface and the device. The condition of most elements that participate in a circuit, including the VCL, the sub-interface, the interface, and the device. Service Information This options brings up the ATM Link Service Information view, which provides information about service providers associated with the ATM network. All service information is entered manually and is provided for reference purposes only. PpATMMpeAcPort and PpATMMpeIfPort Model Types Nortel s multi-protocol encapsulation (MPE) is run over a VCL/VPL link. The MPE has an AC component that represents a virtual channel through which internetworking frames will be transported using rfc1483 encapsulation. The AtmConnection (AC) component contains OSI state information, frame based statistics, and the linkage to an ATM virtual channel connection. This component's instance value is used by higher-layer protocols when referring to a specific ATM connection that oversees each MPE interface. Page 22

23 The sub-interface model type that represents this AC is the PpATMMpeAcPort model type. The PpATMMpeAcPort model type may have one or more MPE subinterfaces represented by the PpATMMpeIfPort model type. This subinterface represents a logical interface between the Virtual Router and an ATM media (AtmIf). Multi-protocol encapsulation as specified in RFC1483 is used to transfer higher-layer protocol data across virtual channels in an ATM network. AtmMpes provide a means to associate multiple ATM virtual channel connections with a single VirtualRouter ProtocolPort. The AtmMpe component is associated with a ProtocolPort via a linkage attribute and virtual channel connections via a linkage attribute in each AC subcomponent. The views available for each of these sub-interface model types show the Nortel ATM MIB objects that support this functionality. For more information on MPE, AC and the Nortel ATM MIBs, see the Nortel Passport 7400 Switch documentation at Interface Reconfiguration When an interface reconfiguration takes place, all ATM sub-interface models will also be reconfigured. An interface reconfiguration can be initiated via the Redundancy and Reconfiguration Model Options in the Device Configuration view, via the Automatically Reconfigure Interfaces option in the Global Attribute Editor, or it may be triggered by changes in the iftable. See the SPECTRUM Views (2517) guide and the Search Manager (2383) guide for more information. Frame Relay Integration The Nortel Passport 7400 Frame Relay integration is available when a SPECTRUM installation includes the Nortel Passport 7400 series management module and SPECTRUM s Frame Relay Manager. To manage Nortel Passport 7400 switches that operate in a Frame Relay environment, the management module supports the standards application RCF1315. When Frame Relay Manager is not installed, RFC1315 is represented by the rfc1315app. See the Transmissions Applications (5064) guide for complete information about this application and its views. When Frame Relay Manager is installed, fr1315app is the application used to represent RFC1315. This application model type has additional Page 23

24 functionality to help you manage your Frame Relay environment. The fr1315app application model type is fully documented in the Frame Relay Manager User Guide (2102). Page 24
