Re: Notification log mib issues

I really need an opinion about my questions to fix it in the right way.
I have fixed it for v5.4.3 and plan to do it for 5.6 too.

Claus

I have some question about  the code at the end of this function:
1.) Why is the send_trap_to_sess() called for each entry at sinks without check the snmpNotifyFilter? 2.) And why is the snmpNotifyFilter called via callback 2 times (with v1 and v2 trap pdu)? 3.) Why is the callback called too if the NETSNMP_DISABLE_SNMPV1 is set? 4.) The standard traps like coldStart is not right logged in this way if send as v1 trap only, how can this fixed? 

The background to my questions is the following scenario:

I have configured 3 trap receiver:
1 trapsink
1 trap2sink
1 informsink

Than each trap is send 3 times and logged 2 times at the nlmLogTable.
That seems for me to be wrong!

It would be nice to get an answer,

Hallo experts,

What is the status of the notification log mib?

The README.agent-mibs is not clear about this mib.
I found that the nlmLogTable and the nlmLogVariableTable is only partly filled for V1 traps. 
I opened a BUG tracker for this, but there is no response?

The different is the v1/v2c trap configuration!

Is this a BUG or not?

Hello
I'm working with net-snmp 5.6 and I checked all with the notification- 
log-mib.
How can it be that the nlmLogNotificationID  is missing while walk?
I can see the initialisation and the adding of a trap at the logfile, 
but the nlmlogVariableTable and tha nlmLogNotificationID is always
missing while walk:

Do someone work with snmptrapd or with notificationLogMib enabled on
snmpd?
