MLM on NT (Win2k) not forwarding traps

["Andy Mindnich1" <MINDNICH@de.ibm.com>]

Hi,
maybe someone can help me with the following problem. I have an attended
MLM setup on a Windows 2000 Server. In Netview (v 6.0.2) the trapfwd 
daemon is
registred to forward all traps to the local machine on port 1662. This 
works fine.
The MLM is now supposed to filter on specific traps and forward only these 
to
a central Netview server running on AIX.

The MLM is configured to listen to port 1662, which seems to work because 
all traps
can be seen in the trap log file of the MLM. The default action is set to 
block traps.
Several filters have been implemented to match on about 8 specific Cisco 
traps
and one filter for all Netview traps. This has worked fine for a while 
now. The matched
traps have been forwarded and displayed correctly in the central Netview 
server.

In a final week of testing and collecting the number of received events 
prior to 
production move we recognized in the middle of the week, that the MLM 
doesn´t send
any traps any more.
We investigated the problem and came to the following conclusion. The MLM 
receives
still all traps from the local Netview, because you can see them in the 
trap log file of the MLM
and the received counter is increased. Even the filter matching seems to 
be working,
because the counters for each filter are updated correctly. 
But no trap packet leaves the box towards the netview server. The trap 
destination
is set correctly and the network interface is running. We had a look at 
the traffic with
the Windows Network Monitor (a kind of sniffer). Polling traffic can still 
be seen, traps
are received and so on. But the MLM doesn´t send any traps to the netview 
server.

Any ideas on this??

The only change happened during this week was, that somebody activated the 
APM
daemon by accident on the AIX box. We disabled it again and deleted the 
trap destination
entry that the APM had configured in the MLM (only the one for APM, not 
the one for the
Netview server).



Mit freundlichen Grüßen / Best Regards
