Hi Jochen,
Objective : On getting Report from NE side saying usmStatsNotInTimeWindow
...call my own ReportHandler and set Engine Boot and Engine Time for that
particular NE as 0 , 0 on manager side. So communication wont stop between
manager and agent.
I have written my own ReportHandler to handle usmStatsNotInTimeWindow.
Scenario :
1) First Manager and Agent both r not in sync
-> On that time manager will send msg to NE and NE will reply back with Report
(usmStatsNotInTimeWindow) and manager will set that (Engne Boot and Engine
Time).
-> On getting this Report my handler gets invoke for Each NE.
Problem :
2) Now communication is going smoothely as both r in sync. But if I change the
time of NESIM (Decrease system time), so both wont be in sync.
-> now when manager sends SET or GET request to NE, NE will reply back with
Report (usmStatsNotInTimeWindow), bcz manager has higher value of NE Boot or
time diff is more than 150.
-> here m facing problem...On getting this Report my handler doesn't get invoke.
question :
1) if I don't override my own ReportHandler then should Default ReportHandler
of SNMP4J gets invoke on getting report from NE??
pls give me some guidance to solve this problem
Thanks
Jigar Shah

Hi,
with the following changes I can see that the default ReportHandler of
Snmp class can be overridden. Maybe you are setting your report handler
on one Snmp object and use another one (with default handler) to send
the request.
