In this chapter, "MSR2000" refers to MSR2003. "MSR3000" collectively refers to MSR3012, MSR3024,
MSR3044, MSR3064. "MSR4000" collectively refers to MSR4060 and MSR4080.
Overview
A configuration file saves a set of commands for configuring software features on the device. You can
save any configuration to a configuration file so the configuration can survive a reboot. You can also
back up configuration files to a host for future use.
You can use the CLI or the Boot menu to manage configuration files. This chapter explains how to
manage configuration files from the CLI.
Configuration types
The device has the following types of configurations: factory defaults, startup configuration, and running
configuration.
Factory defaults
The device is shipped with some basic settings called "factory defaults." These default settings make sure
the device can start up and run correctly when it has no configuration file or when the configuration file
is corrupt.
To view factory defaults, use the display default-configuration command.
Startup configuration
The device uses startup configuration to configure software features during startup. After the device 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 device starts up 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 device reboots, execute the display current-configuration command before making any
configuration changes.
Running configuration
The running configuration includes startup settings that have not been changed and new settings you
made. The running configuration is stored in the memory and is cleared at a device reboot or power off.
To use the running configuration after a power cycling or reboot, save it to a configuration file.
To display the running configuration, use the display current-configuration command.
