Configuring AAA Services on Cisco IOS XR
Software
This module describes the implementation of the administrative model of task-based authorization used
to control user access in the Cisco IOS XR system. The major tasks required to implement task-based
authorization involve configuring user groups and task groups.
User groups and task groups are configured through the Cisco IOS XR software command set used for
authentication, authorization and accounting (AAA) services. Authentication commands are used to
verify the identity of a user or principal. Authorization commands are used to verify that an authenticated
user (or principal) is granted permission to perform a specific task. Accounting commands are used for
logging of sessions and to create an audit trail by recording certain user- or system-generated actions.
AAA is part of the Cisco IOS XR software base package and is available by default.
For a complete description of the AAA commands listed in this module, see the Authentication,
Note
Authorization, and Accounting Commands on Cisco IOS XR Software module in the
Cisco IOS XR System Security Command Reference publication. To locate documentation of other
commands that appear in this chapter, use the command reference master index, or search online.
