Method and device for displaying states of ports of switch

Abstract

The invention provides a method and device for displaying states of ports of a switch. The method comprises the steps that: a backboard reads warning information, system RUN information, state information of each port of the switch, which is sent out by a switching chip, and state information of a power supply module, and the information is input into a microprocessor; and the microprocessor processes the information, and according to a key state, an LED dot matrix is driven to display a result after processing. According to the method and the device, a display unit is arranged on a front panel and a multi-port state display function is provided, so that information of a switch system, a power supply and the state of each port can be vividly and virtually displayed, thereby facilitating system function detection and maintenance. The method and the device are designed on the basis of the ARM Cotex-M3 microprocessor, and are small in package and high in integration level; the device is applicable to mount in a 1U rack type switch; the method and the device adopt a JTAG online modulation mode, are convenient for program writing debugging and easy to maintain, are easy to expand functions, can integrate functions of temperature sensing, heat dissipation management and the like, are suitable to migrate to a blade-type switch, and are wide in application scene.

Description

technical field [0001] The invention belongs to the field of digital computing or data processing equipment specially suitable for specific applications, and specifically relates to a switch port state display method and device. Background technique [0002] Currently, there are two types of switches on the market: those with a display module on the front panel and those without a display module. When a port of a switch without a display module fails, it is often necessary to locate the faulty port through software debugging or through the status of the RJ45 or SFP built-in display lights on the rear panel, which reduces the reliability and ease of maintenance of the switch. [0003] Existing switches with a display module display relatively single information, most of which are the LINK status of all ports, and cannot display speed SPEED and duplex DUPLEX information. [0004] Most of the existing display modules are based on 51 single-chip microcomputer or programmable lo...

AI Technical Summary

Problems solved by technology

The 51 single-chip microcomputer has a large package and takes up a lot of space, which increases the size of the display module, which is not conducive to installation in a 1U rack-mounted switch; and the 51 single-chip microcomputer needs to be equipped with a program writer, and it is installed on the PCB after programming, which may easily lead to booting. bent feet

The package of FPGA is smaller than that of 51 single-chip microcomputer, and it supports online debugging, but it needs to add voltage conversion chip and active crystal oscillator, which increases the module cost; and FPGA has poor expandability, and it is not convenient to add other functions
