I don't see how you would generate a trap without a script which issues some
command like snmptrap. If all you want to do is to send that event to TEC
(Tivoli Event Console -- which is what I take you to mean by TEK -- if not,
please explain) then I think the TEC wpostemsg command would do that for you.
Perhaps some other user has done something like this and can provide you a
sample. I have none.
I also think that you will need a script to do the other processing you want.
Since the four IP addresses are completely independent, there is nothing to tie
them together except your knowledge of what they are. And since one of them
could be down for days before the others fail, I don't see how you could do
anything with a Pass-On-Match or a Reset-On-Match, which require you to specify
a maximum time period to hold the "down" event.
So I think that your ruleset will have to block everything except a NetView
Interface Down trap, and use the Event Attribute Node to determine if they come
from the right box, and then kick off a script in an Action node which will ping
each of the 4 addresses in succession and if all the pings fail, issue the
wpostemsg.
I don't see any other solution. Perhaps someone else does.

James Shanks--
I should be more explicit. NIC is a network interface card, and it is in
a SUN server, and the NIC card has 4 interfaces, each interface connects to
a separate LAN segment, mostly just for high availabality. If one segment
goes
down, the server can still be reached via three different addresses, across
three
different segments/nic interfaces. I only want to generate a node down to
TEK
from Netview if I detect that all four ip addresses are down.
thanks

Jim -
You can generate any trap you like using snmptrap, and you can use a ruleset
to
kick off snmptrap using an Action node. It is the rest of your note which
confuses me .
What's a NIC? Does netmon poll it now? Because there is no way you can
stop
netmon from sending a Node down or Interface down, if it is down, unless
you
unmanage it. What trap are you thinking will drive this ruleset?

I only want to generate a node down if NIC1 AND NIC2 AND NIC3 AND NIC4 are
all
down. Can someone tell me if this do-able with a ruleset ? Each NIC
interface will have
a different ip address.
