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 for Cisco IOS Release 12.
