Based on the Discovery configuration, the Servers, Networks, Links, Printers, and Laptop devices in the organization can be identified. The discovered devices are saved in their respective modules. You can configure multiple subnets for a job and configure protocols, such as WMI, SNMP, SSH and Telnet to discover devices in the given subnet range. You can configure the order of execution of the protocols. After the devices are discovered, you can view the listed devices in the Scanned Result section and the devices that are not listed can be viewed in the Errors Result section.
