It is the primary goal of the tool to SDM2 will help you find your devices that are connected to the network. Once found, they will show up in the main window’s device list.
...
To detect devices, SDM2 uses multiple detection protocols. You can enable and disable each of these, in the Options dialog:
...
The settings shown here are the default settings for SDM2.
To find out how the device in the device list got detected, select it and from the right-click menu choose Edit device(s):
...
Note that different models may be detectable with different detection protocols. Also, the auto detection does not work under certain circumstances. Examples are:
Your device is behind a router. If the detection protocol uses broadcasting, then the device will not be detected, as the discovery message does not pass the router. If the detection protocol uses multicast, it might pass the router, but only if the router is configured so.
De device might have the detection protocol disabled in the firmware configuration, for instance because of security reasons.
The device might not be configured right its network settings. In routed networks, network connections only work right if the device has proper network settings including the default gateway.
In today’s production networks, security has become an increasingly important subject, and auto discovery of the devices has become more and more of a supposed intrusion of the applied security policies. For this reason, it is highly likely that auto detection will not be possible or used in production networks.
Static device list files
If that is the case, then SDM2’s File function must be used instead. It is possible to open an SDM2 device list file (typically extension .xml) containing the device list as it was created manually.
