NerveCenter's Compiled MIB

NerveCenter enables you to control which types of devices are managed based on their SNMP management information base (MIB) definitions. The following diagram shows the NerveCenter MIB files along with the other NerveCenter components.

NerveCenter MIB Files

The compiled MIB file shipped with NerveCenter, NerveCtr.mib, contains definitions for Internet Standard RFC SNMP Versions 1 and 2 agents as well as many vendor specific MIBs. NerveCtr.mib defines the management information available from an SNMP agent based on the MIBs the agent supports. This support information is contained in the .ASN1 file for each managed device. NerveCenter's MIB file enables you to construct SNMP requests for particular devices and to decode data received in SNMP traps.

NerveCtr.mib is compiled from definitions referenced in a text file, which by default is named MibComp.txt. MibComp.txt, in turn, points to the *.ASN1 files you are using. To add support for new devices, modify MibComp.txt to include the new *.ASN1 files, located within the installation/Mib directory. You must have the proper .ASN1 file for each device that is defined.

After modifying the text file, you recompile the MIB file. NerveCenter's MIB compiler, MibComp, verifies each respective .ASN1 file, compiles the definitions in the text file, and creates a new version of NerveCtr.mib that can then be loaded into the NerveCenter Server.
