Description

Implementation method of communication equipment output redirection

technical field

The present invention relates to a data output method in a communication device.

Background technique

At present, when communication equipment outputs its own internal data, such as routers, switches and other communication equipment, when displaying their own working status and listing existing configuration parameters, they usually output all the data to be output on the equipment terminal according to the data output command provided by the user. It is displayed for query. When there is a lot of output data, you need to turn the screen directly to check it. In this way, you can only observe the data on the terminal, and it is difficult to analyze the results. In addition, when locating and solving online problems of communication equipment, since the status of the equipment changes at any time, the data output at different times is different, especially when multiple users perform the same operation, different situations The results obtained by different users may also be different, and the most valuable output data may only be a certain result obtained by a certain user. In addition, when there is a lot of data content output to the user terminal, it is necessary to turn over multiple screens to see the content behind, and if the buffer memory of the user terminal is limited, the turned over content may be lost. Therefore, the existing data output method of communication equipment is single. Due to the complex and changeable network conditions, the results obtained by different users executing data output commands at different times may be different. It is impossible to realize information synchronization and resource sharing, and it is even more difficult to realize data positioning of equipment. and tracking analysis. It can be seen that the data output methods currently provided by communication devices cannot meet the needs of users.

Contents of the invention

The purpose of the present invention is to provide a method for implementing output redirection in a communication device with a flexible data output mode. Using this method is beneficial to realize information sharing of the communication device and facilitate analysis and maintenance of the communication device.

In order to achieve the above purpose, the implementation method of communication device output redirection provided by the present invention includes;

a. Add redirect keywords and redirect file name parameters in the data output command of the communication device;

b. When the data output command sent by the user to the communication device through the network has a legal output redirection parameter, the command processing module of the communication device will store the output data content in the file identified by the redirection file name provided in the command .

Said step b also includes:

The command parsing module of the communication device verifies the legality of the data output command sent by the user through the network.

The command processing module of the communication device judges whether the data output command sent by the user through the network has legal output redirection parameters.

Before writing the output data into the output redirection file, the command processing module also checks the legitimacy of the device storing the redirection file.

Since the present invention adds a data output redirection parameter in the data output command of the communication device, the integrity, real-time and flexibility of the output data are guaranteed; when the output data content is large, the loss of data will not be caused, and at the same time , using the method provided by the present invention can store all the data content output to the terminal into a file, which not only ensures the uniform form and complete content of the data output, but also keeps the data of the device in the current environment, which solves the problem of device analysis, The preservation of real-time data during maintenance, in addition, due to the use of output redirection to save the output data in the form of files, it is beneficial for communication equipment to support local and remote user data sharing.

Fig. 1 is a flowchart of an embodiment of the method of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a flowchart of an embodiment of the method of the present invention. To implement the present invention according to Fig. 1, firstly, the redirection keyword and the redirection file name parameter should be added in the data output command of the communication device. That is to say, in the data output command of the communication device, such as the show command, some parameters related to data output redirection should be added, specifically including: redirection keyword and redirected file name. For the data output command, the redirect keyword is optional, and is used to specify whether the execution result of this command needs to be redirected to a file. If there is this keyword in the command, it means that the execution result of the command needs to be redirected to the file. If there is no such keyword in the command, it means that the output does not need to be redirected this time, and the normal operation is performed. For example, the result of the command execution will be output directly. On the terminal, if the command clearly states that the redirection function is used to realize the output of the result, then the result of show will change the output direction and will no longer be transmitted to the local or remote terminal, but will be stored as a file on the communication device Therefore, the added data output redirection parameter has the characteristics of an optional parameter.

Based on the above content, when the redirection parameter is specified in the data output command, the output data will be stored in the file identified by the redirected file name on the target device (hard disk letter or FLASH).

Specifically, implement the present invention according to Fig. 1, after the user logs in to the specified communication equipment input data output command through the network in step 1, the command analysis module of the communication equipment analyzes and summarizes the data output command sent by the user through the network in step 2 Legitimacy verification, if the verification fails, proceed to step 8 to execute the failure processing operation, and then end the data output command processing; if the verification is passed, the command character input by the user is transferred to the command processing module of the device, and the command processing module is executed in step 8. 3. Determine whether the data output command sent by the user through the network has an output redirection parameter. If there is no output redirection parameter, proceed to step 4 to perform a conventional data output operation, such as outputting data to the device terminal, and then end this session Data output command processing; If judge in step 3 that there is an output redirection parameter in the command input by the user, then the command processing module continues to carry out whether the data output command sent by the user through the network has a legal output redirection parameter in step 5 Make a judgment, if the redirection parameter is illegal, proceed to step 8 to execute the failure processing operation, and then end the data output command processing; otherwise, the command processing module checks in step 6 before writing the output data to the output redirection file in step 7 Store the legitimacy of the redirected file device, if the check fails, proceed to step 8 to execute the failure processing operation, and then end the data output command processing; if the check is passed, the command processing module of the communication device will output the data content in step 7 Go through the process of creating the file and closing the file after writing data into the file identified by the redirected filename provided in the command.

In the specific execution process of step 7, the command processing module also needs to detect whether the memory of the communication device has enough space to store the file, and if there is not enough space, it will forcefully end the execution of the command and return an error. Finally, check whether there is a file name or path name with the same name. After passing the test, create a new file with the specified file name on the specified hardware device, and then write the output content into the file. The file is closed when the output is complete, and the process ends. If an error occurs during file creation, writing, closing, etc., the execution of the command will be forcibly terminated and an error will be returned, and the remaining files will be deleted to prevent space waste.

After the command is executed successfully, this file can be manipulated arbitrarily, for example, you can log in to the communication device locally through the serial port or through the LAN and WAN to browse the file. It is also possible to use the support of the communication device for the file transfer protocol (FTP protocol) to realize local and remote file upload and download, and to share the file.

Finally, it should be noted that the redirection file name must be specified together with the two parameters of the redirection keyword to have the meaning of output redirection.
