Summary of Common Command Modes

Table 4-4summarizes the most common command modes of the Cisco IOS XR software and the associated CLI prompts.

Table 4-4 Common Command Modes and CLI prompts

Command Mode	Description
EXEC	Logging in to an SDR running the Cisco IOS XR software automatically places the router in EXEC
	mode.
	Example:
	RP/0/RP0/CPU0:router#
	EXEC mode enables a basic set of commands to display the operational state of an SDR and the
	Cisco IOS XR software. Most CLI commands in EXEC mode do not change the SDR operation.
	The most common EXEC commands are show commands (to display SDR configuration or
	operational data) and clear commands (to clear or reset SDR counters).
	In EXEC mode, you can display the configuration of an SDR but not the configuration of the
	system. The difference is that SDRs are defined in administration configuration mode, which is a
	submode of administration EXEC mode. SDRs are configured in global configuration mode.
	Additional commands are available depending on the access privileges (user groups) assigned to
	your username. Minimal privileges also include a small set of EXEC commands for connecting to
	remote devices, changing terminal line settings on a temporary basis, and performing basic tests.
Administration EXEC	Administration EXEC mode is used to manage system resources. In administration EXEC mode,
	you can display the configuration of the system but not the configuration of an SDR. The difference
	is that SDRs are defined in administration configuration mode, which is a submode of
	administration EXEC mode. SDRs are configured in global configuration mode.
	Administration EXEC mode is used primarily to display system-wide parameters, configure the
	administration plane over the control Ethernet, and configure SDR. These operations are available
	only to users with the required root level access.
	From EXEC mode, use the admin command to enter administration EXEC mode:
	RP/0/RP0/CPU0:router# admin
	RP/0/RP0/CPU0:router(admin)#
administration	Administration configuration mode allows you to create SDRs and assign system resources to
configuration mode	SDRs. Multishelf systems are also configured in administration configuration mode.
	From administration EXEC mode, use the configure command to enter administration
	configuration submode:
	RP/0/RP0/CPU0:router(admin)# configure
	RP/0/RP0/CPU0:router(admin-config)#
