Stephen,

Go to the menu pick "Options -> SNMP Configuration".  Enter your routers in
the "Specific Nodes" list (use the ip address or name matches their
selection name).  Then for each record, set "Configuration Polling Interval"
to something larger than the 1 day that is the default.  Also turn off
"Discovery Poll".

You can also turn off "Auto Adjust", but leave "Discovery Poll" on, and then
set a large "Fixed Polling Interval" (which should say "Fixed Discovery
Polling Interval", and set it to 1 day or something).  This will allow you
to still do discovery polling (if you need it), but not at the 15 minutes
(or whatever) that Netview does it by default and/or on an auto-adjusted
schedule.

I don't think you can prevent a demand poll from happening if a user does
one, but this will allow you to slow thing down a little bit.

Steve
