Abstract: The present disclosure provides methods, computer-readable media, and systems for managing a network with a network management device. Vendor specific discovery protocol data can be collected with the network management device from a network device in response to the network device having vendor specific discovery protocol data. Vendor neutral discovery protocol data can be collected with the network management device in response to the network device having vendor neutral discovery protocol data. A network connection can be assessed using the at least one of the vendor specific discovery protocol data and the vendor neutral discovery protocol data.
