摘要： According to an example, a guide bracket and an electronic device adopting the guide bracket are provided. A free end of a resilient sheet installed in a wall of the guide bracket is to be held by a snap-fit part set in a chassis beyond the external surface of the wall where the resilient sheet is located to implement position limiting of the guide bracket in the forward-backward direction. The free end of the resilient sheet is to retreat inwards with the bending of the resilient sheet towards the interior of the wall where the resilient sheet is located to avoid the snap-fit part.

摘要： A control plane of a logical network device creates a service link aggregation group and adds one port from each member network device to the service link aggregation group. The logical network device includes member network devices and each port connects the logical network device to the same neighbor device. When a port of the logical network device receives a message with an unknown source address, the control plane determines if the receiving port is in any service link aggregation group. After determining the receiving port is in the service link aggregation group, the control plane configures a data plane of the logical network device with mappings between the address and the ports in the service link aggregation group.

摘要： 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. Instead, the attribute can be registered automatically on ports on both sides of all switches, thus improving the configuration efficiency for port attributes. Furthermore, the present invention can enable propagation of any attribute, thus making the present invention have a high popularity.

摘要翻译： 公开了一种基于光纤通道网络的属性传播方法和交换机系统。 根据本发明，在其一个端口上注册属性之后，每个交换机可以自动使用其另一侧的端口来传播该属性，并且下一个相邻的交换机可以在该端口的同一侧上注册该属性， 使所有交换机一端的端口可以自动注册该属性。 此后，在属性被注册到另一端的端口之后，每个交换机可以自动使用已经注册的所述一方的端口来反向传播该属性，并且下一个相邻的端口可以在另一侧的端口上注册该属性， 使所有交换机的另一端的端口可以自动注册此属性。 这样就不需要手动配置每个端口。 而是可以在所有交换机两端的端口上自动注册该属性，从而提高端口属性的配置效率。 此外，本发明能够实现任何属性的传播，从而使本发明具有很高的普及性。
