Configuring Authentication, Authorization, and Accounting

This chapter describes how to control access to the switch management 

interface using authentication and authorization. It also describes how to 

record this access using accounting. Together the three services are referred to 

by the acronym AAA.
The topics covered in this chapter include:

• AAA Overview
• Authentication
• Authorization
• Accounting
• Authentication Examples
• Authorization Examples
• Using RADIUS Servers to Control Management Access
• Using TACACS+ Servers to Control Management Access
• Default Configurations

AAA is a framework for configuring management security in a consistent way. 

Three services make up AAA:

• Authentication—Validates the user identity. Authentication takes place 

before the user is allowed access to switch services.

• Authorization—Determines which services the user is allowed to access.
• Accounting—Collects and sends security information about users and 

commands.
