Peter,
If the problem is... we use NetView for paging/e-mail, and don't want
a couple of hundred pages/mails once an MLM boots... then here is
a proposed (i.e. you do the programming) solution...

Have the MLM send a coldstart or warmstart trap to NetView when it
reboots.  This trap then could be used as a flag.

Logic play-code... for automatic-action:

if ($mlm_warmstart < 15_minutes_old && $trap_agent eq $A)
  {
  exit;
  }
else
  {
  send_page_and_mail;
  }

This would then suppress any pages/email from that system for
15 minutes.  By that time... you'd hope the MLM was back to a
steady-state.  Of course you have to fill-in the code a little
(whehter perl or rule-set), but that's the gist of the idea.

Regards,

Gary Boyles

As far as I know, what you are describing is normal behavior.  When an MLM
is
rebooted, it starts from ground zero and sends status traps on all the nodes
it
monitors to NetView.  That's what it is supposed to do.  It doesn't have a
topology database like netmon does to store this information in, so it sends
a
level-set to netmon.  It has no idea what happened to the nodes it monitor
when
it is down, whether netmon was able to take over the polling successfully or
not, so it has to start somewhere.  Are you rebooting all your MLMs at once
or
something?  If not, then the question becomes, why have MLMs monitor status
in
the first place if you don't want them to send the traps?

Hello,

Using NT MLMs with AIX NetView 5.12.  When our MLM's are
rebooted, it floods NetView with hundreds of interface up traps.

Don't want to filter the trap as our network people want to see it.
Does anyone have a work around?  Is there a ruleset to handle this?

Thanks,

Peter
