Description: The following two variables are provided as a way of reporting SNMP errors to the management station. The SNMP agent keeps track two variables for each set request (last oid and last error message that was caused by setting the value for last oid). This information is based on the incoming ipaddress and port, so there is only one instance available for each source. The management station will only see errors that is the result of its own set request. If there is no errors available for this source, no value is returned.
