Set the maximum number of ports on a host to limit the number of distributed ports that can exist on one or more hosts associated with a vSphere distributed switch.


Browse to a host in the vSphere Web Client navigator.


Click the Manage tab, and select Networking > Virtual Switches


Select a distributed switch from the list.


Click Update the maximum number of distributed ports on this host.


Use the up and down arrows to set the maximum number of ports for the host and click OK.

If you are changing the maximum number of ports for a host after the host is added to the distributed switch, you must restart the host before the new maximum takes effect.
