All users who can log in to the router or switch must be in a login class. With login classes, you define the following:
1. Access privileges that users have when they are logged in to the router or switch
2. Commands and statements that users can and cannot specify
3. How long a login session can be idle before it times out and the user is logged out
4. You can define any number of login classes and then apply one login class to an individual user account.
