NetView - Can NEW objects be automatically unmanaged?

Question:

Problem:Is there any way that you can configure Netview so that NEW objects in a
managed region, say a token ring network, are automatically unmanaged when
they are initially discovered?  For example, we have managed Hubs on an
existing Token Ring; however, we do not want to manage individual workstations
on this ring.  If a user with a new IP address is added to this ring, Netview
discovers them and when that user shuts down his PC at the end of the day,
that segment will become "marginal", giving an inaccurate view of the status
of the "manageable" part of that network.  Do you have any suggestions to
elliminate this problem?
Yes, you can have devices discovered as unmanaged.  This is accomplished
my making a few adjustments to your /usr/OV/conf/oid_to_type file.

You can specify that any node with a given sysObjectID be discovered
as unmanaged.  You can also specify that any node whose sysObjectID
does not match one in the oid_to_type file be discovered as unmanaged.
Finally, you can specify that those nodes that either do not have
SNMP or whose SNMP is not available (because of, say, community name
issues) be discovered as unmanaged.

The text below explains the changes you have to make (they involve
putting a few ":"s and a "U" after either a sysObjectID or a default
setting like DEFAULT_IP or DEFAULT_SNMP).

  * There are new settings that you can add in the oid_to_type file.
  * The first is DEFAULT_SNMP
    It allows you to specify certain default charactaristics
    for nodes with SNMP whose sysObjIds don't match a specific
    entry in the oid_to_type file.
  * The second is DEFAULT_IP
    It allows you to specify certain default charactaristics
    for nodes without SNMP (or nodes with SNMP but with incorrect
    community names).
  * To have nodes without SNMP discovered as unmanaged, add the following
    line to your oid_to_type file:
      DEFAULT_IP: : :U
    MAKE SURE TO PUT SPACES BETWEEN THE COLONS!!!
    Once you make the change to the file, you must stop and then
    restart the netmon daemon.
  * These settings only affect nodes being discovered.  Nodes already
    existing in the databases will not be changed.
