Abstract:
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.
