I think the ifType2 = 0 is exactly the problem. SNMP now recognizes
something like 145 different ifTypes, but the enumeration begins with "1"
not zero. If we don't think it is a legitimate interface type, then I
don't see how we could draw it. As long as the value is within the
correct range, NetView will identify the interface as "ethernet", when it
doesn't know anything else about it. Also I have seen cases where bad
values on the other end of the scale are returned (one manufacturer
mistakenly returned "2D0") and we could not draw that on the map either,
though it was discovered and in the topology database.
But if you want real help on this, you will have to call Support.

Subject: Re: Nortel device and Netview 5.1 (NT)
Carlos, I asked the question in hopes that someone else would spot the
problem. I hope
you have called support by now, or Nortel. If this were Netview for AIX, I
would guess that
the device does not have ipforwarding enabled, however you do that on such
a device.
I had saved the thread and have attached it below. Nothing looks obviously
wrong to me.

Hi everybody,
Some weeks ago I posted a problem regarding Netview not being able
to find
a Nortel FRAD correctly. Netview created one device for each interface.
Leslie A. Clark asked me for the interface table of the device. I
posted
it but due to problems on my e-mail system I lost the thread.
Any way, I found the following:
interfaces.ifTable.ifEntry.ifType.1 : INTEGER: ethernet-csmacd
interfaces.ifTable.ifEntry.ifType.2 : INTEGER: 0
Is the ifType.2=0 the cause of the problem?
Thank you for your attention.
Best regards,
Carlos Lima Dias
Hi Leslie,
Following is the output of the snmpwalk interfaces:

interfaces.ifTable.ifEntry.ifLastChange.2 : Timeticks: (0) 0:00:00.00
After a few days, Netview created one object for each interface
with the
router symbol. Attached is the output of the ovobjprint for both objects.
Thank you for your attention.
