The Scan Subnets wizard page enables you to create IP address ranges to scan your network for items that can be pinged.
Each IP address range assigns devices to the peer that you are logged onto, creates devices, checks SNMP, and groups devices into a device group with the name you give to the subnet. All subnets are scanned one time when you click the Finish button. The entries you make on this wizard page are duplicated on the Discovery Manager > Watched Subnets tab. The Device Manager displays the devices that data is polled from.
Click Add Subnet to add a row to the list.
In the Subnet Name field, enter the name of the subnet.
In the Start IP Address field, enter the low end of the IP address range.
In the End IP Address field, enter the high end of the IP address range.
Click Update to add the subnet to the list.
Repeat the previous steps to create additional subnets.
Click Next.
