Note The commands available depend on the router mode and your user group assignments.
Step 3 If you belong to a user group that has configuration privileges, you can place the router in the global
configuration mode by entering the configure command:
RP/0/0/CPU0:router# configure
RP/0/0/CPU0:router(config)#
Step 4 From global configuration mode, you can place the router in a configuration submode, such as interface
configuration mode or a protocol-specific configuration mode.
In the following example, the router enters interface configuration mode and the user selects a POS
interface for configuration. The command syntax is interface type rack/slot/module/port.
RP/0/0/CPU0:router(config)# interface POS 0/2/0/4
RP/0/0/CPU0:router(config-if)#
The command mode prompt changes from (config) to (config-if) and you can now enter configuration
commands for the specified interface.
Step 5 To exit interface configuration mode and return to global configuration mode, enter the exit command.
To return to EXEC mode, enter the end command.
Managing Configuration Sessions
In the Cisco IOS XR software, you cannot change the running (active) configuration directly. Enter
configuration changes into an inactive target configuration. When the target configuration is ready for
use, you can apply that configuration to the router with the commit command. This two-stage process
allows you to make, edit, and verify configuration changes before impacting the actual running state of
the router.
Figure 3-5 shows the two-stage configuration process.
