Cisco Discovery Protocol

Cisco Discovery Protocol (CDP) has 4 modes in ESX:
Down = CDP is fully disabled
Listen (default in ESX3.5) = Receives and displays information from other CDP enabled network devices. Does not Advertise
Advertise = Broadcasts the ESX host's network configuration. Does not listen
Both = CDP is fully enabled. Listen & Advertise are both enabled

Configure CDP on a per vSwitch basis with the command
esxcfg-vswitch -B[mode]
