Cisco Discovery Protocol (CDP) allows vSphere administrators to determine which Cisco switch port connects to a given vSphere standard switch or vSphere distributed switch. When CDP is enabled for a particular vSphere distributed switch, you can view properties of the Cisco switch (such as device ID, software version, and timeout) from the vSphere Client.
