•

Configure the KDC by using Kerberos commands.

Configuring the Switch for Local Authentication and
Authorization

You can configure AAA to operate without a server by setting the switch to implement AAA in local
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:
