2 About the Cartridge Components

This chapter provides information about the components of the Oracle Communications Network Integrity MIB-II SNMP cartridge.

The MIB-II SNMP cartridge contains the following actions:

Discover MIB-II SNMP Action

The Discover MIB-II SNMP action discovers a device and creates its hierarchical model.

The MIB-II SNMP cartridge is designed to be used on a standalone basis to display the logical device hierarchy in Network Integrity. The SNMP cartridge provides no integration with other products but can be extended.

The Discover MIB-II SNMP action contains the following processors run in the following order:

  1. MIB-II Properties Initializer Processor

  2. MIB-II SNMP Collector Processor

  3. MIB-II SNMP Modeler Processor

Figure 2-1 illustrates the processor workflow of the Discover MIB-II SNMP action.

MIB-II Properties Initializer Processor

The MIB-II Properties Initializer processor produces the following data sets:

  • snmpVendorNameMap: Contains a snapshot of industry enterprise numbers to help identify devices in the network.

  • snmpIfTypeMap: Contains a snapshot of ifTypes to help identify interface types in the network.

Table 2-1 shows a fragment of each data set output from the MIB-II Properties Initializer.

The content of these files may change from time to time, so they are maintained as part of cartridge revisions. SDK extensions to this cartridge can update the content of the property files. See "About Design Studio Extensions" for more information.

MIB-II SNMP Collector Processor

The MIB-II SNMP Collector processor collects SNMP variables from a device. See "About Poll Lists" for more information.

MIB-II SNMP Modeler Processor

The MIB-II SNMP Modeler processor models the data that is collected by the MIB-II SNMP Collector processor. Modeling includes building the hierarchical relationship of logical device and child interfaces.
