I ever used HP Openview NNM to manage a network and monitor the TCP/IP connection health.

NNM is based on SNMP, but it only use SNMP poll to check the status of nodes that support SNMP. It still use ICMP ping to check the TCP/IP connection health. If I use fireware and forbid ICMP ECHO REPLY, NNM will show the link is down.
