Hi James,
We are using 7.1.3 as well, I assume that the 512-byte limit is the problem.
The sendtrap works fine until I send it with the full
length string for .1.3.6.1.4.1.9.9.311.1.1.2.1.16

Subject: Re: [NV-L] Netview truncating trap variables at 249
chars
I had some time while awaiting a build to run, so I took a closer look at
your snmptrap. I found a number of issues with it, assuming that it was a
cut-and paste of what you actually tried to send.
/usr/OV/bin/snmptrap -d dev109.cs.ctc .1.3.6.1.4.1.9.9.311 42.116.24.30 6
2 '' .1.3.6.1.4.1.9.9.311.1.1.2.1.2 octetstring "1.0"
(1) there is a period or dot missing after the 311 and before the 42
(2) I'm not sure whether dev109.cs.ctc is the source or the destination,
but you must specify both.
(3) timeticks will default, but the syntax is back-to-back double quotes
not single ones
I find it easier to put this kind of thing in a script and get it working
piecemeal, staring with the basic command and then expanding one varbind
at
a time, so that's what I did.
I modified yours to work in my environment, The destination was the AIX
box I ran this one, hence the command hostname enclosed in back-ticks. The
source I spoofed as a box called jshanks2. If you use a hostname it has
to
resolve to a real address in your network; other wise you can use a dummy
IP address.

That's as far as I went. I issued that and got an invalid trap message in
trapd.log, because the last varbind is 532 characters long and trapd has a
512-byte limit in this version
The next version will see that limit raised to 1024, but there is nothing
to be done about it in 7.1.4.
Hope this helps

Send an event command. Just "event" will do, and look again.
If dev109.cs.ctc is your NetView box, and you send the snmptrap, and then
immediately go look for it in trapd.log, then you may not see it because
trapd.log uses buffered I/O. It writes out the last record only on
receipt
of the new one.
But it should show in the trapd trace if you turned on the hex packet
capture as I instructed

This is an example of what Netview is receiving.
.1.3.6.1.4.1.9.9.311.1.1.2.1.16 octetstring
"Unresponsive::Component=42.248.30.201

When I run the following sendtrap having only changed
.1.3.6.1.4.1.9.9.311.1.1.2.1.16 field to the full length string, I get no
indication in Netview that the trap was sent. Nothing in the logs, nothing
in the console. This sendtrap command works fine with the shorter string.

Depends on where this occurs. NetView for UNIX or Windows?
Truncating it where? In the Event display? In trapd.log? In TEC?
249 is an odd number. The maximum length of a varbind that trapd will
support in this version is 512 characters, and I have tested this many
times. But it makes a difference where and how the results are displayed.

I am implementing the CISCO-EPM-NOTIFICATION-MIB and field
cenAlarmDescription (1.3.6.1.4.1.9.9.311.1.1.2.1.16249) contains for than
249 characters. Netview is truncating this field. Is there a setting I can
change to prevent this?
