How does the device Discovery process work?
During the Discovery process, the RN150 virtual machine will use ICMP to verify a device is responsive. Once a reply is received, it will then check if WMI, SSH or SNMP ports are open. Depending on which port is open, the credential information on file in the RN150 will then be used to access the device. If the credential has the appropriate permission level for access, the virtual appliance will then query the device for inventory data. If the inventory commands are successful, the device will be properly “discovered” when the process completes.
