UD Layer 2 Disocvery




Please let me know how UD layer 2 discovery takes place at backend and what information it looks for in network device to draw the topology .



As per my understanding,UD requires end server CI discovered to build topology whereas NNM doesnot require end devices to be managed but still it shows the end node connectiity with host names. For this statement , please correct me if I am wrong anywhere.



with regards,
