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.

1

Log in to the vCenter Server system using the vSphere Client.

2

Select the host to modify in the inventory pane.

3

On the host Configuration tab, click Networking.

4

Select the vSphere Distributed Switch view.

5

Click Properties next to the vSphere distributed switch to modify.

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.
