1.1  Configuration File Management Overview

The management module of configuration file provides a user-friendly operation interface. It saves the configuration of the switch in the text format of command line to record the whole configuration process. Thus you can view the configuration information conveniently.

The format of configuration file includes:

l           It is saved in the command format.

l           Only the non-default constants will be saved.

l           The organization of commands is based on command views. The commands in the same command mode are sorted in one section. The sections are separated with a blank line or a comment line (A comment line begins with a pound sign #).

l           Generally, the sections in the file are arranged in the following order: system configuration, Ethernet port configuration, VLAN interface configuration, routing protocol configuration and so on.

l           It ends with a carriage return.

1.2.1  Displaying the Current-Configuration and Saved-Configuration of Switch

When the switch is being powered on, the system will read the configuration files from Flash Memory for the initialization of the switch. (Such configuration files are called saved-configuration files). If there is no configuration file in Flash Memory, the system will begin the initialization with the default parameters. Relative to the saved-configuration, the configuration taking effect during the operating process of the system is called current-configuration. You can use the following commands to display the current-configuration and saved-configuration information of the switch.

Perform the following configuration to display the configurations of the switch:

1.2.2  Saving the Current-Configuration

You can modify the current configuration of the switch through the command line interface (CLI). Use the save command to save the current-configuration in the Flash Memory, and the configurations will become the saved-configuration when the system is powered on for the next time.

Perform the following configuration to save the current-configuration:

Even if the problems like reboot and power-off occur during the modification, the configuration file can still be saved to Flash memory.

1.2.3  Erasing Configuration Files from Flash Memory

The reset saved-configuration command can be used to erase configuration files from Flash Memory. The system will use the default configuration parameters for initialization when the switch is powered on for the next time.

Perform the following configuration to erase configuration files from Flash Memory:

You may erase the configuration files from the Flash in the following cases:

l           After being upgraded, the software does not match the configuration files.

l           The configuration files in flash are damaged. (A common case is that a wrong configuration file has been downloaded.)

1.2.4  Configuring the Name of the Configuration File Used for the Next Startup

Perform the following configuration to configure the name of the configuration file used for the next startup:

cfgfile is the name of the configuration file and its extension name can be “.cfg”. The file is stored in the root directory of the storage devices.

After the above configuration, execute the display command in any view to display the running of the configuration files, and to verify the effect of the configuration.

Perform the following configuration to display the information of the file used at startup:
