You can export vSphere Distributed Switch and distributed port group configurations to a backup file. The file preserves valid network configurations, enabling transfer of these configurations to other Cloud Foundation systems. You can use the backup file to create multiple copies of the distributed switch configuration on an existing deployment, or to overwrite existing configurations settings.
Use the functionality in the vSphere Web Client tool to create backup files of the distributed switch and distributed port group configurations in your Cloud Foundation system.
For detailed procedures, see Knowledge Base article 2034602 Exporting/importing/restoring Distributed Switch Configs Using vSphere Web Client.
