If an asterisk (*) appears in the Lock column, the user is using an exclusive configuration session and
you cannot start a configuration session until the exclusive configuration session closes. For more
information, see the
Configuration sessions for administration configuration and each SDR are managed independently. For
Note
example, if a user locks the administration configuration, you can still configure an SDR if other users
have not locked a configuration session for that SDR.

Starting a Configuration Session

When you place the router in global configuration mode or administration configuration mode using the
configure command, a new target configuration session is created. The target configuration allows you
to enter, review, and verify configuration changes without impacting the running configuration.
The target configuration is not a copy of the running configuration. It has only the configuration
Note
commands entered during the target configuration session.
While in configuration mode, you can enter all Cisco IOS XR software commands supported in that
configuration mode. Each command is added to the target configuration. You can view the target
configuration by entering the show configuration command in configuration mode. The target
configuration is not applied until you enter the commit command, as described in the
Changes to the Running Configuration" section on page
You can save target configurations to disk as nonactive configuration files. These saved files can be
loaded, further modified, and committed at a later time. For more information, see the
Configuration to a File" section on page
