Overriding SNMP Client Behavior

By default, the SNMP subsystem in Meridian does not treat any RFC 3416 error-status as fatal. Instead, it will attempt to continue the request, if possible. However, only a subset of errors will cause Meridian’s SNMP client to attempt retries. The default SNMP error-status handling behavior is as follows:

Table 1. Default SNMP Error Status Behavior
error-status Fatal? Retry?

noError(0)

false

false

tooBig(1)

false

true

noSuchName(2)

false

true

badValue(3)

false

false

readOnly(4)

false

false

genErr(5)

false

true

noAccess(6)

false

true

wrongType(7)

false

false

wrongLength(8)

false

false

wrongEncoding(9)

false

false

wrongValue(10)

false

false

noCreation(11)

false

false

inconsistentValue(12)

false

false

resourceUnavailable(13)

false

false

commitFailed(14)

false

false

undoFailed(15)

false

false

authorizationError(16)

false

true

notWritable(17)

false

false

inconsistentName(18)

false

false

You can override this behavior by setting a property inside ${OPENNMS_HOME}/etc/opennms.properties in the form:

org.opennms.netmgt.snmp.errorStatus.[statusCode].[type]

For example, to make authorizationError(16) abort and not retry, you would set:

org.opennms.netmgt.snmp.errorStatus.16.fatal=true
org.opennms.netmgt.snmp.errorStatus.16.retry=false
