This is disappointing. VMware specifically calls this "CDP". Yet it does not in fact implement the true cisco discovery protocol either in the network health check or through any of the command line options available to ESXi. I think this is misleading. ESXi is not in fact capable of inspecting a CDP advertisement and pulling all the information from it. Yet it says you have 3 options, "listen, advertise or both". It makes it look just like a Cisco switch implmentation of CDP. Yet it really is not. It can't tell you all the information coming in on the switch advertisement packets. If you come to the ESXi command line expecting ESXi "CDP" to give you the info that the CDP protocol is designed to, you will come away with an incomplete or wrong impression of how things are configured.
