"Notification filters are associated with targets. Did you setup that
relationship properly?"
I believe so. Here is the relevant code:
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.addTargetParams(new OctetString("v2c"),
MessageProcessingModel.MPv2c,
SecurityModel.SECURITY_MODEL_SNMPv2c,
new OctetString("cpublic"),
SecurityLevel.NOAUTH_NOPRIV,
StorageType.permanent);
notificationMIB.addNotifyEntry(new OctetString("default"),
new OctetString("notify"),
SnmpNotificationMIB.SnmpNotifyTypeEnum.trap,
StorageType.permanent);
Without trap filtering, I can receive the coldstart fine this way. The
notificationFilterProfile is connected to the target address only by the "v2c"
targetParamsName (implied), and I *think* I got that right.
"Second, there is no VACM access to the coldStart OID. This will block
the notification too."
Right, I agree. But I don't know what change I need to make in order to add the
VACM access to the coldStart OID. If possible, I'm wondering if you could tell
me how to change the
code I've given to allow that access. I'd like to give free access to any
notification that starts with "1.3.6" (which I'm failing at, as you can see).
After that, I'd like to add exclusion filters to
specify a few individual traps I don't want.
To be clear, I'm only looking for the specific change to the filter to allow
all traps (1.3.6...), for now. If I messed up the appending or implied portions
somewhere, the mask, etc, it would
be great if you might kindly point that out as well.
Thanks again for the help
