PROBLEM TO BE SOLVED: To realize improvement in maintainability in a switching device and a network relay system including the same.SOLUTION: Each port switch PS sets a link aggregation group for m sub-links SL each connecting between the port switch itself and m fabric switches FS. For example, each port switch PS receives a broadcast frame (AF3) for address resolution by (m-1) sub-links (Pf[2], Pf[3]) not including a first sub-link (Pf[1]) which is any one of the m sub-links SL. At this time, each port switch PS permits relay of the frame when the address of its transmission source matches the address of any one of the m fabric switches FS, and destroys the frame when the addresses do not match. |
