Re: [nv-l] Netview Rules Examples

Thanks for the help everyone.  The varbinds are exactly what I thought they were.  Coming from a Network Node Manager background, I am still getting used to the subtle differences between NetView and Network Node Manager.

Thanks Again

If you are talking about the integers in the Event Attribut Selection
dialog box starting under the Community choice, those refer to
varbinds of the SNMP trap.

An snmp trap is a datagram that has a number of attributes including 
        EnterpriseID (OID)
        Origin (ip address/hostname/fqdn)
        Generic trap num
        Specific Trap num
        Community
        and more...
and then a payload of varbinds/slots that might have more goodies:
        varbind 1 
        varbind 2
        .....

What's in the varbinds varies by trap.  For example, a linkdown trap
might include the interface number in varbind 1, but a
ohNoWidgetExploded trap might contain a phone number to a doctor in
varbind 1.  The MIB file for a particular device will give a
description of what each varbind of a particular trap contains.

My apologies if you already know these aspects of SNMP and I've gone
too far with this explanation.
