Description: This table keeps track of the errors that happened when a NMS node tried to a SET operation. Since standard error codes returned by the SNMP response PDU was not comprehensive enough to indicate the actual problem, this table evolved. The NMS node has to keep the request-id field and the UDP port of the SET PDU that is being sent to the Orion SNMP agent. If the response-PDU corresponding to that SET returns an error, NMS node can browse this table with the saved request-id of the failed SET-PDU to get more information about the error.
