Hi,

My opennms version is 1.5.93. However, I found this minor bug might exist on all releases of opennms, even chunk.

Problem Description:
When performs a SNMP SET operation on a device, the SET response PDU contain errors (errorStatus is not 0), and return value is correct (return value = set value). In this case, system (OpenNMS) treats it as a successful SET operation. Actually, it fails.

Additional Info:
It is reproducible, and only happened when devices under management had something wrong in their SNMP implementation. And unfortunately, I met that case.

Resolution:
Update processResponse() method of opennms-snmp/opennms-snmp-snmp4j/src/main/java/org/opennms/netmgt/snmp/snmp4j/Snmp4JStrategy.java to check error status code. Here is the diff result of my change proposal:

334d333
< int errorStatusCode = responseEvent.getResponse().getErrorStatus();
346,350c345
< }
< else if (errorStatusCode!=0) {
< log().warn("TTT send: PDU error status code is not 0: " + a);
< }
< else {
—
> } else {

Regards,
