Hi there! Welcome to my blog. My name is Ivan. I am a Dutch IT Professional working as Principal IT Consultant. Cisco Discovery Protocol (CDP) allows ESX Server 3 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 VI Client. You can use the service console command-line interface to enable CDP.
Using this information and without going to the server room and locating the network cable in the rack I was able to configure the interface on the switch real time.
The switchport should be set as trunk and for security reasons also configure the allowed vlan’s.
