Chapter 10 Configuring Switch-Based Authentication
Configuring the Switch for Local Authentication and Authorization
When you add or create entries for the hosts and users, follow these guidelines:
• The Kerberos principal name must be in all lowercase characters.
• The Kerberos instance name must be in all lowercase characters.
• The Kerberos realm name must be in all uppercase characters.
Note A Kerberos server can be a Catalyst 3750-X or 3560-X switch that is configured as a network security
server and that can authenticate users by using the Kerberos protocol.
To set up a Kerberos-authenticated server-client system, follow these steps:
• Configure the KDC by using Kerberos commands.
• Configure the switch to use the Kerberos protocol.
For instructions, see the “Kerberos Conf

mode. The switch then handles authentication and authorization. No accounting is available in this
configuration.
Beginning in privileged EXEC mode, follow these steps to configure the switch for local AAA:
Command Purpose
