| 摘要 |
A logical port table retains a combination of a physical port and a VLAN identifier in association with a logical port. An FDB retains a correspondence relation between a MAC address and the logical port. When a frame is received at the physical port, a table processing unit acquires the logical port based on the logical port table. An FDB processing unit learns a source MAC address contained in the frame in association with the logical port acquired by the table processing unit to the FDB. |

1. A relay device comprising:
a physical port; a logical port table retaining a combination of the physical port and a VLAN identifier in association with a logical port; a table processing unit; an FDB retaining a correspondence relation between a MAC address and the logical port; and an FDB processing unit, wherein when a frame is received at the physical port, the table processing unit acquires the logical port from the physical port which has received the frame and the VLAN identifier contained in the frame based on the logical port table, and the FDB processing unit learns a source MAC address contained in the frame in association with the logical port acquired by the table processing unit to the FDB. |
