Discover a Network

You can specify a segment of networks to be discovered. CIDR (Classless Inter-Domain Routing) notation is used when specifying IP addresses for network discovery in the user interface. This notation consists of an address and the number of bits to use as the subnet prefix, as shown in the following example:

172.24.143.0/24

You can also use wildcards and ranges:

172.24.143.*

172.24.143.{1-255}

   Ping Sweep

   The Enhanced Discovery and SNMP Information dialog appears.

5. (Optional) Enable Enhanced Discovery to perform detailed discovery using SoftAgent technology.
