AAA Authorization and Accounting
The Authentication, authorization, and accounting (AAA) feature provides the main
framework for configuring access control on the switch. The three security functions
can be summarized as follows:
• Authentication — Identifies users that request access to the network.
• Authorization — Determines if users can access specific services.
• Accounting — Provides reports, auditing, and billing for services that users have
accessed on the network.
The AAA functions require the use of configured RADIUS or TACACS+ servers in
the network. The security servers can be defined as sequential groups that are then
applied as a method for controlling user access to specified services. For example,
when the switch attempts to authenticate a user, a request is sent to the first server
in the defined group, if there is no response the second server will be tried, and so
on. If at any point a pass or fail is returned, the process stops.
The switch supports the following AAA features:
• Accounting for IEEE 802.1X authenticated users that access the network through
the switch.
