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 session closes. For more information, see the 
.
Note
Configuration sessions for administration configuration and each RSP are managed independently. For 
example, if a user locks the administration configuration, you can still configure an RSP if other users 
have not locked a configuration session for that RSP.
Starting a Configuration Session
When you place the router in global configuration 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. 
Note
The target configuration is not a copy of the running configuration. It has only the configuration 
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 type the commit command, as described in th
.
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 th

Simple RSP Configuration: Example
This example shows a simple owner RSP configuration session in which the target configuration is 
created and previewed in global configuration mode:
RP/0/RSP0/CPU0:router # configure 
RP/0/RSP0/CPU0:router(config)# interface tunnel-te 2
RP/0/RSP0/CPU0:router(config-if)# show configuration
