Managing configuration files
You can use the CLI or the BootWare menus to manage configuration files. This chapter describes only
managing configuration files from the CLI.
Overview
A configuration file saves configurations as a set of text commands. You can save the running
configuration to a configuration file so the configuration takes effect after you reboot the switch. You can
also back up the configuration file on to a host and download the file to the device as needed.
Configuration types
The switch has the following types of configuration: factory defaults, startup configuration, and running
configuration.
Factory defaults
The switch is shipped with some basic settings called "factory defaults." These default settings make sure
the switch can start up and run correctly when it has no configuration file or the configuration file is
corrupted.
Factory defaults vary with device models and might differ from the default settings of commands.
To view the factory defaults of the switch, use the display default-configuration command.
Startup configuration
The switch uses startup configuration to configure software features during startup. After the switch starts
up, you can specify a different configuration file to be loaded at the next startup. This configuration file
is called the "next-startup configuration file." The configuration file that has been loaded is called the
"current startup configuration file."
If no next-startup configuration file exists, the switch boots with the factory defaults.
You can view the startup configuration in either of the following ways:
•
Execute the display startup command. To view detailed file contents, use the more command.
•
After the switch reboots, execute the display current-configuration command before making any
configuration.
Running configuration
Running configuration includes startup settings that have not been changed and new settings you have
made. It is stored in a volatile storage medium and takes effect while the device is operating.
A new setting takes effect immediately after it is made but must be saved to a configuration file to survive
a reboot.
To view the running configuration, use the display current-configuration command.
