The best way is to do a network discovery, where agent discover and
associate SNMP model if device supported. This task get few
informations of devices, but reuired to identify them.

One you have do this the first time, you will do a network inventory
(SNMP) to get all data of the devices.

To begin, see this is a good beginning.
