Hello,

The forwardall.rs ruleset is used be default in the Event Display, so
this
is where it is probably getting loaded. There is no relationship between
the rulesets that are used by ESE.automation, Event Display, or TEC
forwarding using tecint.conf. Each one has it's own destination for
forwarding events to, so the forwardall.rs in the Event Display will not
override what the ruleset in tecint.conf for TEC forwarding.

Ok I ran the "nvcdebug -n" command. The output is as follows

2006/24/10 09:46:38   CorrelationDef.C[562] :   Current running
correlation:
CorrelationDefinition(0x30033b08)
+  RootDnode
+  +  RuleSet forwardall.rs
+  +  +  Forward(19) Corrnode application=0x303d2888
+  +  RuleSet test.rs
+  +  +  EventAttributes (Attr='EnterpriseID'  ne
Value='.1.3.6.1.4.1.9.1.502')
+  +  +  +  EventAttributes (Attr='Origin'  ne  Value='42.231.8.3')
+  +  +  +  +  EventAttributes (Attr='Origin'  ne  Value='42.2.1.12')
+  +  +  +  +  +  EventAttributes (Attr='Origin'  ne  Value='42.2.1.13')
+  +  +  +  +  +  +  EventAttributes (Attr='Origin'  ne
Value='0.0.0.0')
+  +  +  +  +  +  +  +  Forward(130) Corrnode application=0x30062d18

I do not know why the forwardall.rs is being loaded. The ESE.automation
file is as follows

#This file should contain a list of filenames
#that will be autmatically started by actionsvr.
#Each rule set name is on a separate line; the pund sign
#indicates a comment line.
#An example line, with the name commented out) is below:
#your_ruleset_here.rs

Am I correct in assuming that the forwardall.rs is forwarding everything
before the test.rs even gets a look at it?

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
