Well, the first thing I would do is edit the format in trapd.conf (using
xnmtrap) and just change it to say something like
"Trap $G $S received: $*" so that what you get in the event window is the
generic and specific id and all the variables listed. That will tell you
whether or not the variables you were trying to format were really there or
not.
If you still think there is a problem, then you will have to call Support. But
first I would get a hex trace of the incoming trap. Use the Tivoli desktop (or
SMIT) to set the "hex dump of all packets" option on the trapd daemon. This
will cause him to write those to the trapd.trace log. Once trapd is running
with this option ( -x) you can control when he traces by issuing the command
"trapd -T " from the command line to toggle the tracing on and off. Support
will need the hex dump of the incoming trap , as well as your trapd.conf to
figure things out.

Subject: Re: trap daemon: can it receive SNMPv2 and SNMPv1 traps?
James,
First of all, when I talk about SNMPv1 and SNMPv2, I use the phrases used in
Dave Perkins book understanding MIB's.
A v2 trap there has the SNMP type a7.
That type we saw coming from a UCD agent. We try to set it(the agent) to
SNMPv1 traps(should be possible according the man page) but that didn't
work, no traps at all were sent then.
So we're forced to v2 by the UCD agent.
In the event window(control desk) we see: "FMT ERROR: accessing element #2,
only 1 available" and "FMT ERROR: accessing element #4, only 1 available"
for a trap(type a7).
Because we're not quite sure about the values in the var binds I raised this
question.
Hope this clarifies the question.
THanks.
