- Create a csv file (as shown below) with the details of name/ipaddress of the device, displayname and device type.

- Browse and select the CSV file from which you want the devices discovered and imported.
- Provide the correct netmask.

Note: If you are using DHCP protocol on your network, make sure that both the forward and reverse lookup gets resolved before you add the devices to OpManager Plus.
Discover Interfaces
- Go to Settings > Discovery > Discovery - Interface

Scheduled Discovery
- We can have Opmanager Plus do a scheduled discovery at specific intervals which sweeps the IP range you entered and adds the devices using the conditions mentioned during the discovery.
- This can be saved as a profile to be executed per schedule and the report can be e-mailed as well.
- We can have Discovery reports which gives you information on what device was added and when.
