Delete a Distributed Switch

You cannot delete the default distributed switch while it still has joined hosts.
You cannot delete a distributed switch if distributed pot groups in the distributed switch are referenced by a VM memory snapshot.
You cannot delete a distributed switch if distributed port groups in the distributed switch are associated with Kernel adapters.

In the navigation pane, choose Inventory > Network Resource.
In the resource tree, select a target distributed switch.
On the target distributed switch's details page, click Actions > Delete.

Deleting a distributed switch deletes all its distributed port groups and detaches associated VM NICs. Proceed with caution.
