Ignoring ICMP Only Nodes

If you select Ignore nodes that only respond to ICMP (ping) you will eliminate nodes that do not respond to SNMP or WMI. When ICMP only nodes are discovered NTM can only discover that some device is responding at the IP address. No node details or connectivity can be discovered for ICMP only nodes.

We recommend you select the ignore ICMP only nodes option.
