Logging In to a Router

F I N A L D R A F T — C i s c o C o n f i d e n t i a l

•A Remote Authentication Dial In User Service (RADIUS) server

•A Terminal Access Controller Access-Control System Plus (TACACS+) server

The username and password validation method that your router uses is determined by the router configuration. For information on configuring username and password validation methods, see the Cisco ASR 9000 Series Aggregation Services Router System Security Configuration Guide. For information on which username and password to use, see your system administrator.

To log in to the router, enter your username and password when prompted. For example:

User Access Verification

Username: cisco

Password: password

RP/0/RSP0/CPU0:router#

Note Passwords are case sensitive. If you want to log in to the router using a root-system username, type the username in the following format: username@admin. To support admin login, local database authentication must be enabled with the aaa authentication login remote local command. For more information, see the Cisco ASR 9000 Series Aggregation Services Router System Security Configuration Guide.

After you log in, the router displays the CLI prompt, which is described in the “CLI Prompt” section on page 3-6. The command set that you can use is determined by the privileges assigned to your username. For information on how privileges are assigned to usernames, see the Cisco ASR 9000 Series Aggregation Services Router System Security Configuration Guide.

CLI Prompt

After you log in, you see the CLI prompt for Cisco IOS XR Software. This prompt identifies the router to which you are issuing commands. The CLI prompt represents the path, through the router, to the CPU that executes the commands you enter. The syntax for the CLI prompt is: type/rack/slot/module: router-name#. The CLI prompt is described in Table 3-1.

Table 3-1 CLI Prompt Description

		Prompt Syntax Components	Description
		type	Type of interface or card with which you are communicating. For
			most user communication tasks, the type is “RP.”
		rack	Rack number. In a standalone router, the rack number is always “0.”
		slot	Slot in which the RSP is installed. In a Cisco ASR 9000 Series router,
			the RSP physical slot number is “RSP0” or “RSP1.”
		module	Entity on a card that executes user commands or communicates with
			a port (interface). For executing commands from the EXEC prompt,
			the module is the “CPU0” of the RP. “CPU0” also controls the
			forwarding and operating system (OS) functions for the system.
		router-name	Hostname of the router. The hostname is usually defined during
			initial configuration of the router, as described in the “Configuring
			the RSP Hostname” section on page 3-32.
