When CDP is set to listen or both, you can view Cisco switch information.


Log in to the vSphere Client and select the host from the inventory panel.


Click the Configuration tab and click Networking.


Click the info icon to the right of the vSwitch.


Because the CDP advertisements of Cisco equipment typically occur once a minute, a noticeable delay might occur between enabling CDP on ESX and the availability of CDP data from the vSphere client.
