I would have done it as indicated below in a December 15th post from Jane Curry.
This "positive" seed file entry would not impact the database.
Please get back to us (good or bad) with database impact using the negative (!@oid) entry.
Thanks,
Don Davis

To totally prevent discovery of non-SNMP nodes in NetView V5, specify as
a statement in the seedfile:
@oid 1.3.6.1.*

This specifies the total group of SNMP-nodes with OIDs beginning with
1.3.6.1. Non-SNMP-devices are not included in this group, thus they are
excluded from discovery.

Cheers, Jane

You may discover only SNMP devices by putting !@oid 0 at the end of your seed
file.
