ABSTRACT:
Packet switch operating methods and packet switches compare a quantity of virtual interfaces associated with a virtual switch to a threshold. If the quantity of virtual interfaces is not greater than the threshold, and the packet switch is configured to learn forwarding fields of packets forwarded by the virtual switch, the methods and switches configure the packet switch to not learn forwarding fields of packets subsequently forwarded by the virtual switch. Other methods and packet switches compare a quantity of virtual interfaces associated with a virtual switch to a threshold. If the quantity of virtual interfaces associated with the virtual switch is not greater than the threshold and the packet switch is configured to learn forwarding fields of packets forwarded by the virtual switch, the methods and packet switches configure the packet switch to not learn forwarding fields of packets subsequently forwarded by the virtual switch.
