One of the exciting new dvSwitch features in vSphere 5.1 is the ability to export and restore a dvSwitch configuration. This new feature is only available through the vSphere Web Client.
On Hypervisor.fr, a blog you should have in your RSS reader, there were already posts on how to configure the dvSwitch healthcheck and how to do a dvSwitch configuration rollback from PowerCLI. But till now, as far as I know, there were no functions to provide the dvSwitch export/restore functionality.
Time to make this useful functionality available for the “PowerCLI automation crowd” 😉
