Question

What is the error message that occurs when the manager sends Set_Request to a read-only object? Also, list out any three error messages in SNMP v1.

Answer 1

The error status and error index field should indicate the initial variable that could not be restored due to the error indicated by the error status. To determine if any of the remaining variables cannot be retrieved, the displayed error needs to be corrected (e.g. Variables removed from request, modified OID, etc.) and the request re-submitted. At that point, the error status and the response problem index will indicate the next variable and error (if any).
