Chapter 3 Configuring General Router Features
CLI Prompt
If you log in to a router with a single SDR configured (this is the default configuration), you can manage
the entire router.. If you log in to a named SDR, you can manage only that SDR. For more information
on SDRs, see the “Secure Domain Routers” section on page 3-27.
When you log in, the username and password may be validated by any of the following services:
• Usernames configured on the router (username command in global configuration mode)
• Root-system usernames configured on the owner SDR
• Passwords configured for the router console and auxiliary ports (password or secret command in
line configuration mode)
• RADIUS server
• 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
Cisco IOS XR System Security Configuration Guide for the Cisco XR 12000 Series Router. 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: iosxr
Password: password
RP/0/0/CPU0:router#
Note Passwords are case sensitive. To log in to an SDR using a root-system username from the owner SDR,
enter 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 Cisco IOS XR System Security Configuration Guide for the Cisco XR 12000 Series
Router.
After you log in, the router displays the CLI prompt, which is described in the “CLI Prompt” section on
page 3-37. 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 Cisco IOS XR System Security
Configuration Guide for the Cisco XR 12000 Series Router.
CLI Prompt
After you log in, you see the CLI prompt for the Cisco IOS XR software. This prompt identifies the
router or SDR 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#. Table 3-1 describes the CLI prompt.
