We are doing same for traps from many vendors - all the way from layer 2 to

You need to load the trap definitions provided by this vendor (hopefully you
will have those). And loading v2 trap definitions to Netview, in my
experience, have always been fun :) 

Once you verify reception of these traps at Netview, then configure your tec
fwd ruleset to forward these to TEC. Make sure you have appropriate BAROC
definitions for these events on the TEC server.

I am very happy you are asking these questions.

Allow me to further articulate what we are trying to engineer here.

There is a SNMP agent on the Siteminder policy server that will send traps.
We are hoping to use Netview to interpret those traps so that we can forward
those events on to the Tivoli Enterprise Console's Event Server for

I was under the impression in order to define events for TEC process, traps
need to go to Netview. What really got me excited is that I can build events
based on the SNMP traps received.

Thank you for the spirited conversation and collaboration. This is fun! :-)

I'm afraid I still don't understand.  Will you be receiving traps from this
application's SNMP agent?  Will you be polling this SNMP agent? In SNMP,
those are your two options -- wait for an agent to send an SNMP trap to
signal trouble, or periodically do SNMP GET's from the agent to see if
things are okay.

NetView does primarily 3 things to automatically monitor hosts in a
hands-off setup where you don't have an operator pointing and clicking
through a mib browser:
        o pings em  (not applicable to application monitoring though)
        o Periodically snmpwalk a subset of the SNMP agent's MIB for
          config changes.
        o Can use snmpcollect to poll specific mib values on the agent
          or combinations of values/formula to see if anything has
          exceeded a threshold.

And none of these three things actually requires that a mib be loaded on

The only benefits to loading mibs into NetView  are:
        o allows you to use an snmp mib browser to interactively point
          and click your way through the hierarchy and do sets and
          gets on those values from a target SNMP agent/device

        o it assigns names to numeric OID values in certain log files,
          snmpwalks and in trapd.log  (but I'm not even sure if that
          applies to the v2 mib tree)

        o The snmpcollect GUI uses the v1 mib browser to allow you to
          interactively specify an OID for data collections and
          thresholds settings.  This does not apply to snmpv2 mibs
          though--for collections on v2 mibs you have to manually
          place the snmpv2 OID into snmpCol.conf becaus the browser
          won't get ya there. 

So I'm left questioning still "why is it you want to load snmp v2 mibs into
netview, and do you really need to do it to get where you want to go?"
