That's certainly where the problem was - fixed it now (well, it works
anyway!).
I found initially it was my test trap from nvsnmptrap that wasn't right
and the variables didn't match the constants in the ATTR statements
which themselves came from the .oid file.

But then I found while my test trap was working, the actual application
event still wasn't.  I did start to see a mapping to "VB_1", "VB_2" etc
variables for my data (not sure why I didn't see that before).  

I changed the ATTR statements to refer to these VB_x variables rather
that the constants I had put in the .oid file (the VB_x has the same
number of the variable in the trap definition so they must be related -
i.e. 1.3.6.1.4.1.11.2.17.2.0 was mapped to VB_2).  And that made it
work....

I'm happy it works, but I think I'll look at this again in the morning
to see if I can see some doc's on it.

Oh for a FMT file for this adapter!!!

Thanks anyway.

Karl

I'm not deep into CDS file but based on what you've posted and as you
pointed out, the trap fails the SELECT statements. I met a couple of
similar situations and the experiences tell me if all other traps get
processed fine except this several, , then probably it means this
several traps received have missing bound variables or mismatch variable
names.

I solved the problems by examining the trap PDU data (through sniffer
program) and/or manually generate the trap
by snmptrap command from NetView server.

Subject:    [nv-l] tecad_nv6k CDS file


Hi,

(apologies in advance if you sub to the tme10 list as well - I've cross
posted because this one sits pretty much in the middle of the two
subjects).

I'm having a little bit of trouble editing up a CDS file for the
tecad_nv6k adapter.

>From the trace I've got (below) I think the event is being discarded 
>all
the time, but I can't see how/why it is doing that.  I should be able to
get the omnibackEvt event processed properly....  The adapter is working
ok for other events and the trap looks ok in the netview event list.

Anyone got a view where I'm going wrong.....or if anyone has found some
good documentation on this yet, that would be useful...

trace file:
