Patent number: 8792386Abstract: An attribute propagation method and a switch system based on a fiber channel network are disclosed. According to the present invention, after an attribute is registered on one of its ports, each switch can automatically use its port on the other side to propagate this attribute, and a next adjacent switch can register this attribute on its port on the same side, so that ports on one side of all switches can have this attribute registered automatically. Hereafter, after the attribute is registered its port on the other side, each switch can automatically use its port on said one side that has been registered to propagate this attribute reversely and a next adjacent can register this attribute on its port on the other side, so that ports on the other side of all switches can automatically have this attribute registered. In this way, there is no need to manually configure each port.Type: GrantFiled: September 3, 2010Date of Patent: July 29, 2014Assignee: Hangzhou H3C Technologies Co., Ltd.Inventors: Yingjun Guo, Feiyu Li, Feng Zhang
