Abstract

A network system includes a plurality of fabric switches and a plurality of port switches connected to the plurality of fabric switches through a plurality of links. A link aggregation group is set to the plurality of links connected to the plurality of fabric switches, and when the port switch receives a multicast management frame, it transfers the frame to each of the plurality of fabric switches. The fabric switch has a table in which information of a port which has received a frame and a source MAC address of a received frame are registered, and when the fabric switch receives the multicast management frame, it registers information of a port which has received the frame and a source MAC address of the frame in the table.

Description

technical field [0001] The present invention relates to a network system and a network relay device. For example, in a VXLAN (Virtual eXtensible Local Area Network), a network system and a network relay device are effective for transmitting and receiving frames between VMs (Virtual Machines: virtual machines). Background technique [0002] As a network technology, VXLAN is known that can cope with the increase of tenants and applications. In addition, as shown in Patent Document 1, a network system having a two-layer structure composed of a lower layer and an upper outer layer is known. [0003] In a network system composed of a lower layer and an upper outer layer, the lower layer is constituted by a plurality of lower switches to which terminal devices are connected. In addition, the upper layer is constituted by a plurality of upper switches respectively connected to a plurality of lower switches. At this time, frame transmission and reception between terminal devices c...
