I think you'll have to go shopping for a new SNMP manager, I'm afraid
(though I'm curious how they intend to block all snmpv1 access). 

Every SNMP GET request that NetView makes uses SNMPv1 PDU's, as far as
I know.  The only exception I'm aware of is a specific interactive
browsing with the latest web mib browser when you tell it to user v2
PDU's for the query.

I'm afraid so.

I don't think the collector will work for you because it relies on the
backward compatibility of snmpv2 devices to do its magic.  It sends v1
GET's (which v2 devices by standard are supposed to honor, but in your
case they evidently won't have that functionality enabled). 

Actually trapd receives v2 traps largely okay (with the exception of a
coruption issue of the last few bytes that I can't remember the
details of it).

If you use MLM's however, they throw away v2 traps and you're sunk.
