Network Discovery
Peregrine Desktop Inventory can contribute data to Network
Discovery
Peregrine Desktop Inventory (PDI) scanners can be scheduled from Network
Discovery and scan files can be added to a shared directory on the Peregrine
appliance, so the scanned devices will appear in the Network Discovery
database, and on the Network Map.
For more information on setting up PDI to contribute data to Network
Discovery, see
Using Network Discovery with Desktop Inventory and Desktop
Administration .
Why it’s important to prepare
Setting up Network Discovery is quick and easy, provided you properly prepare
your network, and use the specified equipment for the Peregrine appliance and
the management workstation.
To operate correctly, Network Discovery needs a constant supply of accurate
data. To ensure that Network Discovery knows where and how to collect that
data, you must do a little preliminary work. You only have to do this once.
The complete physical connectivity of your network can only be portrayed
accurately when:
„
all community strings are provided to Network Discovery
„
all network connectivity devices are SNMP managed
„
no network devices use proxy ARPing
„
no critical entries appear in the Network Exceptions report
If devices do not conform to the standards or fail to respond correctly and
consistently to SNMP polls, Network Discovery may not be able to create an
accurate inventory.
