Overview
1 Overview
This document applies to both the Ericsson SmartEdge ® and SM family routers.
However, the software that applies to the SM family of systems is a subset of
the SmartEdge OS; some of the functionality described in this document may
not apply to SM family routers.
For information specific to the SM family chassis, including line cards, refer to
the SM family chassis documentation.
For specific information about the differences between the SmartEdge and SM
family routers, refer to the Technical Product Description SM Family of Systems
(part number 5/221 02-CRA 119 1170/1) in the Product Overview folder of
this Customer Product Information library.
This document provides an overview of the authentication, authorization, and
accounting (AAA) features of the Ericsson SmartEdge and SM family routers
and describes the tasks used to configure, monitor, and administer AAA. This
document also provides AAA configuration examples.
Note: In the following sections, the term controller card refers to the
Cross-Connect Route Processor (XCRP4) Controller card. The term
controller carrier card refers to the controller functions on the carrier
card in the SmartEdge100 chassis.
1.1 Authentication
The following sections describe the authentication features for administrators
and subscribers.
1.1.1 Administrators
By default, router configuration authenticates the administrators. You can also
authenticate administrators through database records on a RADIUS server, on
a Terminal Access Controller Access Control System Plus (TACACS+) server,
or on both the servers sequentially.
You must configure the IP address of a reachable RADIUS or TACACS+
server (or both) in the context in which the administrator is configured. You
can set a maximum limit on the number of administrator sessions that can be
simultaneously active in each context. For information about RADIUS and
TACACS+, see Configuring RADIUS and Configuring TACACS+ respectively.
