Abstract: In one embodiment, an apparatus includes a processor configured for operation in a control plane in a distributed virtual switch in communication with a plurality of virtual machines each having a virtual interface. The processor is operable to identify other control planes in the distributed virtual switch, assign a virtual interface identifier to one of the virtual interfaces, receive a configuration for the virtual interface, and share the configuration with the other control planes in the distributed virtual switch. The virtual interface identifier provides a unique identifier for the virtual interface across all of the control planes. The apparatus further includes memory for storing the configuration of the virtual interface. A method for operating a network device associated with a control in the distributed virtual switch is also disclosed.
