NMP-00002:

no such SNMP variable name
Cause: An SNMP request was not processed because the one or more of the variable names in the request does not exist. This error is not normally visible to the user except in a trace file, where it is usually part of a "soft" error condition which is normal.
Action: The error may indicate that a managed server does not support an operation requested by its control program, perhaps because of version incompatibility. For further details, turn on tracing and re-execute the failing operation. If the error persists, and does not occur as part of a "soft" error condition as noted in the trace file, contact Worldwide Customer Support.
