1. There's a setting in trapd-configuration.xml, "new-suspect-on-
trap", that tells openNMS to initiate a Capsd service scan on any
unknown node from which an SNMP trap is received.
2. If a device's IP address changes (DHCP, accidental change,
introduction of a NAT, etc.) but it's still sending traps to openNMS,
you won't lose those traps.
Why would you configure devices that you don't manage with openNMS to
send traps to openNMS?
