Description
Technical field
The present invention relates to switch port state management technology field, in particular to a kind of pipe of multi-exchange port status
Manage system and method.
Background technique
In interchanger product, whether cassete exchange machine or frame-type switch, plate can design interchanger in front
The indicator light of port status is used to indicate the link state and active state of port.When multi-port connection terminal, link instruction
Lamp lights, and when port disconnects, indicator light off by link；When port has data to be received and dispatched, the flashing of active indicator light, when
When port no data is received and dispatched, indicator light off by active.
Existing switch can obtain each port status of exchange chip by processor, and then it is each to control multiple LED lamps expressions
The state of port, but this method occupies the treating capacity of processor, influences the working efficiency of system, and there are multiple exchange boards
When, multiple processors are both needed to occupy treatment effeciency, increase the complexity of system.
Present Botong's exchange chip supports two paths of LED pin, LED_CLK and all the way LED_DATA all the way, in exchange core
It include LED processor inside piece, the serial signal of output can indicate the state of each port of exchange chip.
Therefore the present invention is based on Botong's exchange chips to propose a kind of management method of multi-exchange port led status lamp.
Summary of the invention
In order to solve problems in the prior art, the present invention provides a kind of management system of multi-exchange port status and sides
Method can greatly improve the operational efficiency of switch system.
The technical solution adopted in the present invention is as follows:
A kind of management system of multi-exchange port status, including CPLD logic controller, the connection of CPLD logic controller one end
LED_CLK the and LED_DATA pin of interchanger exchange chip, other end connection indicate the LED light of port status, serial data
It is transferred to CPLD logic controller by two pins of LED_CLK and LED_DATA, the CPLD logic controller will be described
Serial data carry out serioparallel exchange processing, the LED light is sequentially output according to clock pulses.
CPLD logic controller indicates the LED light of port status by the connection of LED pin, according to the height of LED pin electricity
The light on and off of flat control LED light.
Serial data includes the clock interval between port number, link state, active state and signal.
A kind of management method of multi-exchange port status, comprising the following steps:
A, LED_CLK with the LED_DATA pin of the exchange chip of interchanger is connected into CPLD logic controller, CPLD logic control
Other pins connection of device processed indicates the LED light of port status；
B, the control program in the drive software of exchange chip about LED is modified, LED controller is made to adjust output as needed
Serial data；
C, the serial data is carried out serioparallel exchange processing by the CPLD logic controller, successively defeated according to clock pulses
The pin for arriving connection LED light out controls the light on and off of LED light according to the low and high level of pin.
Technical solution provided by the invention has the benefit that
LED_CLK with the LED_DATA pin of each exchange chip is connected CPLD logic controller, CPLD logic control by the present invention
Other pins connection of device indicates the LED light of port status, and the LED controller in exchange chip adjusts the string of output as needed
Row data, such as need the clock interval between the port number, link state, active state and the signal that indicate.Serial number
It is transferred to CPLD logic controller according to by two pins of LED_CLK and LED_DATA, serial data is gone here and there and turned by CPLD
Processing is changed, the pin of other connection LED light is sequentially output according to clock pulses, LED light is controlled according to the low and high level of pin
Light on and off, the real-time status of port is showed by LED light by this process.
This method can using the serioparallel exchange function of CPLD logic controller based on the LED processor inside exchange chip
The port status of multiple exchange boards to be indicated by the output of the same logic controller simultaneously.Interchanger itself is not needed
System processor carries out any processing, improves the operational efficiency of switch system.
