Abstract: A line unit holds in its active table data a number that indicates which flooding setting table is to be made active. An input frame forwarding unit embeds the number in an internal frame header of a frame that is to be output. As the number is embedded before the frame is forwarded to each line unit via a backboard, the output destination for the same frame is determined by a common active flooding setting table. Thus, frame destruction or duplication is prevented.

Abstract: A network system includes a maintenance terminal and a switch that transfers a packet. Upon receiving a link-trace message packet, the switch transfers, when links to the destination constitute a link aggregation, the link-trace message packet to all physical links constituting the link aggregation. In response to the link-trace message packet, the switch receives a link-trace reply packet from each of the physical links, and generates link-trace result data. the link-trace result data is output to the maintenance terminal.

Abstract: A communication device and method for restraining frames from being discarded when the number of physical links constituting a communication path has changed while at the same time keeping the traffic amounts of the individual physical links as even as possible. A table memory stores an allocation table showing the correlation between addresses included in incoming frames and the physical links via which the incoming frames are to be output. On detecting a fault of a physical link, a setting controller manipulates the allocation table to divide the range of addresses allocated to the faulty physical link into multiple sections to be reallocated among normal physical links. When a frame is received, a switch looks up the allocation table and determines, in accordance with the address included in the received frame, which of the normal physical links is to be used to output the received frame.
