Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0043] See figure 1 , in one embodiment, the network device includes a main control board and an interface board. in:

[0044] The main control board has a CPU, a control serial port, and a first control logic device;

[0045] The first control logic device is connected between the CPU of the board and the control serial port through the on-board serial port bus;

[0046] The first control logic device is connected to the interface board through an inter-board access bus; wherein, the inter-board access bus is independent of the data bus for normally exchanging data between the main control board and the interface board;

[0047] And, the first control logic device switches and connects the on-board serial port bus on the control serial port side wit...

Abstract

The invention discloses a network device and a console configuration method for the network device. Based on the network device and the console configuration method for the network device, through switching communication of a console of a main control panel, communication between the console of the main control panel and a CPU of a principle panel can be achieved through an intra-panel serial port bus so that the main control panel can use a console of the principle panel, and the console of the main control panel can also be communicated to an interface panel through an inter-panel access bus so that the interface panel can use the console of the main control panel. Thus, the interface panel in the network device can reuse the console of the main control panel so that the requirement of the interface panel for using the console can be met.

Description

technical field [0001] The invention relates to network technology, in particular to a network device and a control serial port configuration method for the network device. Background technique [0002] A network device usually includes a main control board and an interface board, wherein the main control board has an external control serial port (CONSOLE) for controlling the network device. The interface board often also needs to use the control serial port, for example, to start debugging or repair the CPU of the interface board, but the interface board does not have an external control serial port. Contents of the invention [0003] In view of this, the present invention provides a network device and a control serial port configuration method for the network device. [0004] A network device provided by the present invention includes a main control board and an interface board; [0005] The main control board has a CPU, a control serial port, and a first control logic...
