This feature is about CloudStack network plugin for baremetal advanced networking. With this plugin, CloudStack
can automatically program vlan on physical switch to which baremetal instances connect when creating/destroying
baremetal instance. This feature cannot work standalone, it needs support from physical switch itself either from
vendor’s SDK or from an in-switch agent for whitebox switch. When using this feature, baremetal instances gain
Layer 2 isolation methods provided by CloudStack advanced networking which is particularly useful in public cloud
that wants to provide baremetal as a service.
