Ray, you know more than you think you
do.
But I'm still confused, so maybe you
should posts a couple of concrete examples.
But for the sake of argument let's say
you have a trap coming into NetView with OID .1.3.6.1.4.1.9.9.224 and it
has three variables. The first is threshold, the second rogue app,
and the third is clients associated. Presumably these variables
go over to TEC as different slots, along with hostname, and the usual stuff.
So if your device sends a trap A, which says P1=500, P2=agent1, and
P3=client1, client2, client3; and then it sends trap B, which says P1=600,
P2=agent3, and P3=client4, client5, client6; how are these not different
slot values?
Also, I have the dup-detect thing backwards.
You say dup_detect= yes for some field so that TEC doesn't
trash events which are otherwise duplicates except for that field.
We use dup-detect for hostnames for example, so that a Node Up for
host A is not tossed because we get one for host B. So I'm
having a hard time seeing how that would not do the same thing for these
events.
If it truly is the case that all the
fields are the same, then my question is, "how do you tell the events
apart in NetView?" By timestamp? In that case,
you could always have ovactiond kick off a script which adds that, and
forwards to TEC with postemsg, or uses snmptrap to send an event of your
own design, which you then froward to TEC instead of the original.

yep that one came up.
The dup detect rules are based on slot values and these are based on the
varbind arguments that are forwarded. Since the subtree 224.1.x.x.x
does not parse into slots the dup does not see them as separate events.

I'm not certain but I think the solution to your problem is in TEC. Now
my TEC skills are not hot, but they have a duplicate detection thing going
on over there, which is configurable. Have you asked them about turning
it off? If memory serves me, then somewhere in your TEC rules you
can say dup_detect = no and then the events are treated as individual just
like they were sent.
Anyone else?

go easy I have only been using NV for 6 months.
I am attempting to Configure the Cisco's Wireless LAN Solution Engine to
forward traps to NetView and then have NetView forward Events to the TEC
Console.
NV 7.1.3 fp02 on Solaris, TEC 3.7, WLSE release 2.5fcs which
manages the 1150 and 1200 series access points.
I searched the archives and found entries for monitoring access points
dated 2001. These entries referenced the 350 ap's and spoke of 802.11
mibs. This unfortunately did not shed light on my problem.
The wlse refers to cisco-device-exception-reporting-mib.my. This
creates the oid .1.3.6.1.4.1.9.9.224 ciscoMgmt. I was having trouble
running mib2trap and opened a pmr. Support guided me thru extracting
the 224. trap from the mib and enlightened me on how wonderful cisco mibs
are.
The Problem is;
wlse appliance options allow you to identify and forward events of interest
to a north-bound trap receiver. Everything from rogue ap detection
to RF thresholds. These can be setup with a P1, P2, P3 and so on.
When these event traps are forwarded they all come under the ciscoMgmt
224 oid. (This is where I am learning, be kind) The ?varbind? arguments?
for the additional 224.1.x.x.whatever that allow one to parse the ?varbind?
trap ? arguments ? for the different P1 threshold, P1 rogue ap detect,
P1 clients associated. All come under the top level 224. trap.
This is fine if the staff were only looking at the NV event browser. Since
I am forwarding these events to TEC what happens is the duplicate arguments
do not work since all the messages come from wlse and the 224ciscoMgmt
oid. So every event that comes after the first one overwrites the
previous.
Is there another way to do this? Or shall I take Cisco TAC up on
there offer to work with NetView Support and identify and then creating
a more complete mib that parses the varbind arguments for the WLSE Appliance?
Any Ideas? Or am I totally off base here and someone is about to
take me to school? (which I probably need)
