  • Progressive MAC address learning
    Patent number: 10284469
    Abstract: One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a storage device, a hardware management apparatus, and a layer-2 management apparatus. The storage device stores a forwarding table, which includes an entry comprising a MAC address and an egress port for the MAC address. The hardware management apparatus determines whether a destination MAC address of a frame is present in a hardware table in memory of the switch. The layer-2 management apparatus, in response to a determination that the destination MAC address is not present in the hardware table, looks up a first entry comprising the destination MAC address in the forwarding table, and creates a second entry comprising the destination MAC address in the hardware table based on the first entry.
