Problems solved by technology

[0003] Existing switches can obtain the state of each port of the switching chip through the processor, and then control multiple LED lights to indicate the state of each port, but this method occupies the processing capacity of the processor and affects the working efficiency of the system, and when there are multiple switching boards , multiple processors need to occupy processing efficiency, which increases the complexity of the system

Embodiment 1

[0022] as attached figure 1 As shown, the management system of a kind of multi-switch port state of the present embodiment comprises a CPLD logic controller, and one end of the CPLD logic controller is connected to the LED_CLK and LED_DATA pins of the switch chip, and the other end is connected to an LED light representing the state of the port. The row data is transmitted to the CPLD logic controller through two pins of LED_CLK and LED_DATA, and the CPLD logic controller performs serial-to-parallel conversion processing on the serial data, and sequentially outputs to the LED lights according to the clock pulse.

[0023] The CPLD logic controller connects the LED lights indicating the port status through the LED pins, and controls the LED lights to turn on and off according to the high and low levels of the LED pins.

[0024] The serial data in this embodiment includes port quantity, link state, active state and clock interval between signals.

Embodiment 2

[0026] A method for managing port states of multiple switches, comprising the following steps:

[0027] A. Connect the LED_CLK and LED_DATA pins of the switching chip of the switch to the CPLD logic controller, and connect the other pins of the CPLD logic controller to the LED lights indicating the port status;

[0028] B. Modify the LED control program in the driver software of the switching chip, so that the LED controller can adjust the output serial data according to the needs;

[0029] C. The CPLD logic controller performs serial-to-parallel conversion processing on the serial data, sequentially outputs the clock pulses to the pins connected to the LED lights, and controls the LED lights to turn on and off according to the high and low levels of the pins.

Abstract

The invention relates to the technical field of management of switch port states, and in particular relates to a system and method for managing multiple switch port states. The method in the inventionis as follows: on the basis of an LED processor in a switch chip, by utilization of the serial-parallel conversion function of a CPLD logic controller, port states of multiple switch board cards canbe output and shown through the same logic controller at the same time. A system processor of a switch itself does not need to do any processing; and thus, the running efficiency of a switch system isincreased.

Description

technical field [0001] The invention relates to the technical field of switch port state management, in particular to a management system and method for the state of multiple switch ports. Background technique [0002] In switch products, whether it is a fixed switch or a modular switch, there are switch port status indicators on the front panel to indicate the link status and active status of the port. When the port is connected to a terminal, the link indicator is on, and when the port is disconnected, the link indicator is off; when the port has data to send and receive, the active indicator flashes, and when the port has no data to send and receive, the active indicator is off. [0003] Existing switches can obtain the state of each port of the switching chip through the processor, and then control multiple LED lights to indicate the state of each port, but this method occupies the processing capacity of the processor and affects the working efficiency of the system, and...
