That's right. For Netview to discover it and draw it, it must respond to a
ping.
In your case you can do what we all do when dealing with firewalls, which
are
often set up the same way (no ping, yes snmp from this address). You can
manually add the node (Edit..Add..Object). Netview will take it from there.
While you are in the Add dialog that you pay a visit to the ipmap
configuratrion
dialog to check the address and mask. And be sure you add it at the correct
submap level. Go inside the segment inside the subnet if you are adding
a 'Computer'.
Cordially,

i would think a successful "discovery" requires a response to a ping as a

Well the reason that I want to use SNMP status rather than pings is that
ICMP echos are blocked at a private VLAN boundary, but SNMP isn't.
Which brings me to my question. I attempted to SNMP status query 2 Nokia
Crypto Clusters (actually it's an HA config with 2 boxes and a 3rd shared
address). I can snmpwalk the two systems, but as stated earlier ICMP
echos are blocked. For some reason, the two boxes will not discover.
I'm not sure if it is because pings are blocked, or that there is a 3rd
virtual address. I am about to try tracing netmon and all that, but
figured I would look out here and just see if anyone has tips or ideas.
Thanks in advance.

Just a question on why you would want to do this.
Since the overhead involved to get status via SNMP rather than by ping is
so much greater, why would you want to make that the default? Getting
status via SNMP is a very new feature in NetView and it should be used
sparingly, which probably accounts more than anything else for why you
cannot simply set things up as you suggest. I think product management
would want to see a full-blown performance analysis before they'd let such
a feature out the door. But that is just my opinion here.
If you think this should be a feature, then my suggestion is that you call
Support and open an enhancement request.

Subject: [NV-L] OIDs Seedfiles and SNMP status polling
Hi All
I am attempting to have my cake and eat it, so please don't flame me for
presenting an unreasonable request:
I have a seedfile that contains IP addresses and IP address. What I would
like to do is status poll most of the devices using SNMP. However, if I
understand correctly, one must first discover the object and then add the
"$" before the IP address or hostname in the seedfile.
So I had an idea: how about using OIDs - maybe I can put the following line
in my seedfile and run "netmon -y" (it's the OID of a printer)
$@oid 1.3.6.1.4.1.2001.1.2.683.6
No such luck.
Therefore, the only solution that I can think of is to work through the
database to see which objects have been discovered and support SNMP and
have the appropriate OID and update the seedfile accordingly (not
forgetting the netmon -y afterwards).
I'm sure that someone out there has had to deal with the same issue.
Wouldn't it be great if there was a flag you could set somewhere that says
"If the object supports SNMP, use SNMP to status poll it"?
Any ideas anyone?
Cheers.
Danny
