Configuring Authentication, Authorization, and Accounting
• Login — Login authentication grants access to the switch if the user
credentials are validated. Access is granted only at privilege level one.
• Enable —Enable authentication grants access to a higher privilege level if
the user credentials are validated for the higher privilege level. When
RADIUS is used for enable authentication, the username for this request is
always $enab15$. The username used to log into the switch is not used for
RADIUS enable authentication.
•
dot1x
—Dot1x authentication is used to grant an 802.1X supplicant access
to the network. For more information about 802.1X, see "Configuring Port
and System Security" on page 469.
Table 10-2 shows the valid methods for each type of authentication:
Authorization
Authorization is used to determine which services the user is allowed to
access. For example, the authorization process may assign a user’s privilege
level, which determines the set of commands the user can execute. There are
three kinds of authorization: commands, exec, and network.
• Commands : Command authorization determines which CLI commands
the user is authorized to execute.
• Exec : Exec authorization determines what the user is authorized to do on
the switch; that is, the user’s privilege level and an administrative profile.
