Managing the System Configuration
The XSR’s system configuration consists of three discrete types which are
described below. The configuration can also be reset to default settings, saved,
and uploaded or downloaded in bulk fashion.
 Factory Default Configuration: These system parameters are set at the
factory. If you make configuration changes and do not save them or
the startup configuration file cannot be found, the XSR reverts to the
factory default configuration.
 Startup Configuration: These system settings are used as the current
running configuration when you power up or issue the
reload
command. The startup configuration is stored in non-volatile (Flash)
memory as the
startup-config file. The file contains a version
number followed by a series of CLI commands. When the XSR
restarts, each CLI command in this file is read and executed.
 Private Configuration: The
private-config file contains SNMP v3
related commands. When the XSR restarts, each CLI command in this
file is read and executed. The file is updated or created when the
running configuration is saved to the startup configuration.
 Running Configuration: These system settings, known as
running-
config
, include a version number followed by accumulated
commands from
startup-config and user revisions. Changes made
to the configuration are lost if you power cycle or reboot unless you
save it to
startup-config using the copy or write command.
The XSR validates commands as they are entered and rejects with an error
message those commands which are invalid.
Resetting the Configuration to Factory Default
In situations where the XSR does not have valid software or is experiencing a
problem booting up, you can reset the router and return it to its factory
default settings by accessing Bootrom Monitoring Mode.
Enter Bootrom mode by simultaneously pressing the
CTRL and C keys during
the first five seconds of system initialization. You can then access a menu
which allows system initialization from the factory default setting.
Refer to the XSR CLI Reference Guide and XSR Getting Started Guide for more
details about Bootrom Monitoring Mode.
