Thanks James,
So to use "Log Only" I will have to load or build the trap entries in the
trapd.conf?
The <> was meant to imply the "not equal to" option.

Subject: Re: [NV-L] Ruleset Editing Questions
If you use xnmtrap and set the trap to "Log Only" It will not be sent to
TEC nor display in your event windows but it will be kept in trapd.log so
that you can gauge how many you are getting. You can also set the trapd to
"Don't Log or Display" and this will keep it from the log as well, but
then you'll have no way of knowing what's going on if start having a
performance problem because too many of these traps are arriving.
Cisco devices are highly configurable. You usually can configure just the
traps you want and even the frequency that they are sent. Perhaps you
should talk to your network guys about that and solve the problem at the
source. Remember that getting a lot of unwanted traps isn't just a
nuisance. It's a performance issue, not just for NetView, but for everyone
else on the same subnet. That's their potential bandwidth you are eating
and throwing away.
As for your ruleset, I'm not sure what it is supposed to say. Greater than
or less than the OID? Why not just "not equal to" ?
But in any case you can tell exactly what ruleset you are running in two
ways. If you are keeping an nvserverd.log, then the name will be in there,
as will evidence of the reload. But whether you are or are not keeping the
nvserverd.log, you can issue "nvcdebug -n" which will cause nvcorrd to
write out in detail to his log what rulesets he is running. You can see
the contents of the ruleset there. You can also debug this way by sending
"nvcdebug -d all" and then observing what happens to each event as it is
evaluated. Everything between the eyecatcher "Received a trap" and
"Finished with the event" is nvcorrd processing that event.

[NV-L] Ruleset Editing Questions
I am trying to set up some rules to filter out traps coming for
Ciscoworks. We are getting way to many now that the network guys have
turned it on.
Is there a way to simply drop traps that have not been defined in the
trapd.conf? I do not want to keep them in Netview or forward them to TEC.
On a side note I am having trouble setting up simple rules.
I am receiving a trap from Ciscoworks with the OID of 1.3.6.1.4.1.9.1.502
I do not want this forwarded to TEC
In the ruleset defined in tecint.conf I created an Event Attributes rule.
It looks like this:
Event Stream -> (EnterpriseOID <> 1.3.6.1.4.1.9.1.502) -> Forward
I ran the nvtecia -reload command to reload the ruleset and I am still
getting these forwarded. Is there something else required to load modified
rulesets?
Sean
