Network Device Drivers

This Wiki is deprecated and we are are currrently migrating remaining pages into product documentation (Admin Guide, NXSL Guide)

Network device driver is a special kind of server module which handles device specifics for SNMP devices (for example, retrieving VLAN information in most cases is vendor or device specific). Drivers are written in C++.

Driver Selection for Device

Driver selects the device type in two steps. On first step, server pass device information to each driver’s isPotentialDevice method. This method should return 0 if driver cannot support this device or priority in range 1 - 255 if device can be potentially supported. On second step, server calls method isDeviceSupported for each driver which responds positively on first step, going from highest priority drivers to lowest priority drivers. First driver responding with true is selected as driver for the device. If no drivers were selected, built-in generic driver will be used.
