摘要: An apparatus for decreasing the hardware load from L2 switch MAC address learning Ethernet-Over-SONET technology that uses VLAN, simplifying frame transmission between Ethernet and SONET, improving reliability of each device is disclosed. SONET convertible interface part establishes a register holds an specific VLANID STS path ID in opposition, multiplexing multiplexes having corresponding to held by among input plurality VLAN ID's.
