Cisco Systems 3750E manual Protecting Access to Privileged Exec Commands

Chapter 9 Configuring Switch-Based Authentication

Protecting Access to Privileged EXEC Commands

•If you want to use username and password pairs, but you want to store them centrally on a server instead of locally, you can store them in a database on a security server. Multiple networking devices can then use the same database to obtain user authentication (and, if necessary, authorization) information. For more information, see the “Controlling Switch Access with TACACS+” section on page 9-10.

Protecting Access to Privileged EXEC Commands

A simple way of providing terminal access control in your network is to use passwords and assign privilege levels. Password protection restricts access to a network or network device. Privilege levels define what commands users can enter after they have logged into a network device.

Note For complete syntax and usage information for the commands used in this section, see the Cisco IOS Security Command Reference, Release 12.2.
