Just a couple of things - I don't know if they will help -- and if not, you
may want to take the issue up with Support so that someone can separate the
important facts from the rest. If you are truly having a problem, you will have
to investigate it one interface and node at a time.
First, you must distinguish between Node Up/ Node Down events and Interface Up/
Interface Down events. These are not the same and will not be issued under the
same conditions. Interfaces will be Up or Down depending on whether they
respond to pings, but Nodes will be Up or Down depending on the status of all
their interfaces. So if you have a node with more than one interface, and a
particular one goes down, but the others remain up, you get an Interface Down
event for that interface but a Node Marginal, not a Node Down event, for the
node. The Interface Down/Node Down, Interface Up/Node Up is only synonymous when
there is only one interface on the box. So there first thing is to make sure
you are looking at the right set of events.
Second, NetView basically sends an event every time a status in the database
changes. He does not discard any. You could build a ruleset to do that, but
that is not a default function for the product.

Subject: multiple netview mlm up traps
Hello
On Aug 1 router "X" went down i received a down event, 3 hrs later when
the router
came up I received a up event. On Aug 2,3,4,6 I also received up events,
no downs.
On Aug 9 router "X" went down again, i received a down and a up event
On Aug 14,14,16,17,19,20,23,24 I also received up events, no downs.
This is just a example of 1 router. The problem is wide spread.
The router/interface only went down twice down. Why am I getting all of
these up events ?
The up events are for every interface on the router. The down event is
for only one interface.
The traps are all netview traps from a AIX MLM.
Should netview be discarding all of these traps since the are no
corresponding
down traps ?
why is netview generating all of these traps ?
If the problem was a missed poll/ping one would expect to see down
events not up.
Any ideas
thanks Rob
