Chapter 1  Configuration File Management

1.1  Introduction to Configuration File

A configuration file records and stores user configurations performed to a switch. It also enables users to check switch configurations easily.

Upon powered on, a switch loads the configuration file known as saved-configuration file, which resides in the Flash, for initialization. If the Flash contains no configuration file, the system performs initialization using the default settings. Comparing to saved-configuration file, the configuration file which is currently adopted by a switch is known as the current-configuration.

A configuration file conforms to the following conventions:

l           The content of a configuration file is a series of commands.

l           Only the non-default configuration parameters are saved.

l           The commands are grouped into sections by command view. The commands that are of the same command view are grouped into one section. Sections are separated by empty lines or comment lines. (A line is a comment line if it starts with the character “#”.)

l           The sections are listed in this order: system configuration section, physical port configuration section, logical interface configuration section, routing protocol configuration section, and so on.

l           A configuration file ends with a “return”.

1.2  Configuration File-Related Operations

You can perform the following operations on an S3100-52P Ethernet switch:

l           Saving the current configuration to a configuration file

l           Removing a configuration file from the Flash

l           Checking/Setting the configuration file to be used when the switch starts the next time

l           Setting a configuration file to be the primary/secondary configuration file

Perform the following configuration in user view.

Table 1-1 Configure a configuration file

In the following conditions, it may be necessary for you to remove the configuration files from the Flash:

l           The system software does not match the configuration file after the software of the Ethernet switch is updated.

l           The configuration files in the Flash are damaged. The common reason is that wrong configuration files are loaded.

You can save the current configuration files in one of the following two ways:

l           If the safely keyword is not provided, the system saves the configuration files in the fast mode. In this mode, the configuration files are saved fast. However, the configuration files will be lost if the device is restarted or the power is off when the configuration files are being saved.

l           If the safely keyword is provided, the system saves the configuration files in the safe mode. In this mode, the configuration files are saved slowly. However, the configuration files will be saved in the Flash if the device is restarted or the power is off when the configuration files are being saved.

You are recommended to adopt the fast saving mode in the conditions of stable power and adopt the safe mode in the conditions of unstable power or remote maintenance.
