Hi,
I'm using the following code to setup and then send notifications both
to a defined V1 and V3 target. It seems that the V1 notification goes
out but for V3 it fails with VACM access denied. Please help me, I'm
hopeless.
protected void addNotificationTargets(SnmpTargetMIB targetMIB,
SnmpNotificationMIB notificationMIB) {
log("Adding notification targets");
targetMIB.addDefaultTDomains();
targetMIB.addTargetAddress(new OctetString("notificationV2c"),
TransportDomains.transportDomainUdpIpv4,
new OctetString(
new UdpAddress("127.0.0.1/162").getValue()),
200, 1,
new OctetString("notify"),
new OctetString("v2c"),
StorageType.permanent);
targetMIB.addTargetAddress(new OctetString("notificationV3"),
TransportDomains.transportDomainUdpIpv4,
new OctetString(
new UdpAddress("127.0.0.1/1162").getValue()),
200, 1,
new OctetString("notify"),
new OctetString("v3notify"),
StorageType.permanent);
targetMIB.addTargetParams(new OctetString("v2c"),
MessageProcessingModel.MPv2c,
SecurityModel.SECURITY_MODEL_SNMPv2c,

new OctetString("v3notify"),
SecurityLevel.NOAUTH_NOPRIV,
