Authentication, Authorization, and Accounting Commands on Cisco IOS XR Software
username
SR-98
Cisco IOS XR System Security Command Reference
From global configuration mode, you can display all the configured usernames. However, you cannot
display all the configured usernames in username configuration mode.
Each user is identified by a username that is unique across the administrative domain. Each user should
be made a member of at least one user group. Deleting a user group may orphan the users associated
with that group. The AAA server authenticates orphaned users but most commands are not authorized.
If you want to require a username and password on the console or for Telnet sessions, configure
authentication using both the aaa authentication login default local command and the username
command.
The predefined group root-system may be specified only by root-system users while administration is
configured.
Note To enable the local networking device to respond to remote CHAP challenges, one username command
entry must be the same as the hostname entry that has already been assigned to the other networking
device.
