The IP Manager uses proprietary MIBs in addition to standard MIBs because standard MIBs do not always contain the information that is needed by the IP Manager to discover and manage certain objects. Standard MIBs, for example, do not represent the processor or memory objects that are necessary for performance analysis. In these cases, proprietary MIBs offer more detailed information.
Proprietary MIBs are also known as enterprise, vendor-specific, or private MIBs. Standard MIBs are also known as generic MIBs.
