CLI Prompt
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
• Passwords configured for the router console and auxiliary ports (password or secret command in
line configuration mode)
• RADIUS server
• TAC ACS+ 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
. 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

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 .
After you log in, the router displays the CLI prompt, which is described in the “CLI Prompt” section on
page 52. 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 .
