Cisco Discovery Protocol
Cisco Discovery Protocol (CDP) allows ESX administrators to determine which Cisco switch port is connected to a given vSwitch. When CDP is enabled for a particular vSwitch, you can view properties of the Cisco switch (such as device ID, software version, and timeout) from the vSphere Client.
Enable CDP on an ESX Host
vSwitches are set to detect Cisco port information by default. You can also set the CDP mode so that a vSwitch makes information available to the Cisco switch administrator.
