I missed your second question. No. Or Yes. If you are on V6.01 with
Router Fault Isolator enabled, then, yes, finding one node unreachable
(status poll times out) will cause netmon to revise it's normal polling
sequence to investigate that subnet more closely. But if RFI is enabled,
you should not be getting Down events for things besides router interfaces.
Generally speaking, though, slow response does not cause polling,
especially of the network is unmanaged. Now, you want to make sure
that the things inside the network are unmanaged as well. But if something
is unmanaged, it does not get polled.
Ask again if this is not helpful. I may only be confusing you.

Subject: Re: [NV-L] discovery events
There was another map on second netview, but not local to netview server. I
don't know whether that interface, which is umanaged by default map,
managed by this map or not cause customer deleted that map after I told him
to check that map.
Anyway, the default map is the only map that exist in second system. So
netmon will not poll that unmanaged interface any more?
I have question about delayed reponse to the status polling. Does extra
traffice on the subnet caused by the first system cause second system to do
status polling?
Thanks & Best regards,

My guess would be that the second system, on whose map you say
that subnet is unmanaged, has at least one other map and that subnet
is managed on at least one of them. The extra traffic on the subnet
caused by the first system's rediscovery is causing delayed response
to the status polls of the second system.
To check for multiple maps on the second system, do File...Open and
see what maps are listed. If there is only the 'default' map, then I, too,
am mystified.

I have two netview servers in diffierent subnetwork, they are supposed to
work independently. When I do automatic map generation on one netview,
another netview server also get a lot node down events from the subnet
which is unmanged by him. Does anybody know how it happened?
