With Link Layer Discovery Protocol (LLDP), vSphere administrators can determine which physical switch port connects to a given vSphere Distributed Switch. When LLDP is enabled for a particular distributed switch, you can view properties of the physical switch (such as chassis ID, system name and description, and device capabilities) from the vSphere Web Client.
