    • A network device includes a first and a second control board, with each control board having a separate control plane and fabric plane. The network device is configured to establish an active control plane on the first control board and an active fabric plane on the second control board. The network device is configured to establish a standby fabric plane on the first control board and a standby control plane on the second control board. The network device is configured to detect a failure on the first control board or the second control board and switch the status of the control plane on the second control board from standby to active, when the failure is on the first control board, and switches the status of the fabric plane on the first control board from standby to active when the failure is on the second control board.
    • 网络设备包括第一和第二控制板,每个控制板具有单独的控制平面和结构平面。 网络设备被配置为在第一控制板上建立主动控制平面,并且在第二控制板上建立主动结构平面。 网络设备被配置为在第一控制板上建立备用架构平面和在第二控制板上建立备用控制平面。 网络设备配置为检测第一个控制板或第二个控制板上的故障,并将第二个控制板上的控制面板的状态从待机状态切换到主动,当故障出现在第一个控制板上时, 当第二个控制板发生故障时,第一个控制板上的Fabric平面的状态从待机状态变为活动状态。
