Normally, I would recommend you look at polling intervals and timeouts,
since that controls what when netmon decides that an interface is down and
sends the traps. I would suggest a separate entry in the SNMP
Configuration for these entries with a longer timeout. If that's not
working, perhaps you might try a netmon trace to see what is happening
here. If you need help with that, I'd call Support and ask for it.
The ruleset issue is more puzzling to me, because in principle, this is
just the sort of thing Pass/Reset-On-Match should do well. The problem may
be your timing however. Ten seconds is way too fine an increment for the
daemon to handle. The heartbeat mechanism for checking the threshold is
set at 15 seconds, so it would be impossible to get good results lower than
that. Why not have him hold it for a minute or two? Then if there is
going to be an UP event, you are sure not to miss it.

Subject: Node/interface UP/Down Reset on Match
Sometimes we receiving a Node/Interface Down event and a second or two
later he Node/Interface Up event is received, especially on our
International links. I have tried to adjust the timeout and retry
intervals for these nodes but this problem still occurs. I would like to
hold the down messages for about ten seconds to see if the up message is
received, if not then forward the down event on to our T/EC console. A
ruleset using the Reset on Match might be the way to go, but I'm having
trouble getting that to work. Any suggestions on dealing with the rule
or this situation is greatly appreciated.
We are running NetView V4.1 on AIX 4.1.5
