Dave - it depends.....
The default mechanism is that NetView will ping every interface that it knows
about, every 5 minutes. You have great flexibility to configure this polling
interval for nodes, networks or SmartSet collections.
With 6.0.1 and later, if a box supports SNMP, it can tell NetView if it has
Unnumbered Serial interfaces - if that happens, NetView will automatically
swap from ping-polling to SNMP-polling that box.
You also have the choice to customise any nodes you wish to use SNMP-polling,
rather than ping-polling. You do this either via netmon's seedfile or via
customising the oid_to_type file in /usr/OV/conf.
For SNMP-polled nodes (whether user configured or auto-configured), the
polling interval is the same as configured in the usual SNMP configuration
panel (Options -> SNMP Configuration) - ie. use the same panel entry for
ping-polling and SNMP-polling.
Hope that helps,
Jane
