Chapter 3 Configuring General Router Features
Logging In to a Router
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.
Ta ble 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.
