Chapter 30 Configuring Switch Access Using AAA Configuring Authentication Table 30-2 Default Authentication Configuration (continued) Feature Kerberos login authentication (console and Telnet) Kerberos enable authentication (console and Telnet) Kerberos server IP address Kerberos DES key Kerberos server auth-port Kerberos local-realm name Kerberos credentials forwarding Kerberos clients mandatory Kerberos preauthentication Default Disabled Disabled None specified None specified Port 750 NULL string Disabled Not mandatory Disabled Authentication Configuration Guidelines This section lists the guidelines for configuring authentication on the switch: • Authentication configuration applies both to console and Telnet connection attempts unless you use the console and telnet keywords to specify the authentication methods to use for each connection type individually. • If you configure a RADIUS or TACACS+ key on the switch, make sure that you configure an identical key on the RADIUS or TACACS+ server. • The TACACS+ key must be less than 100 characters long. • You must specify a RADIUS or TACACS+ server before enabling RADIUS or TACACS+ on the switch. • If you configure multiple RADIUS or TACACS+ servers, the first server that you configure is the primary server, and authentication requests are sent to this server first. You can specify a particular server as primary by using the primary keyword. • RADIUS and TACACS+ support one privileged mode only (level 1). • Kerberos authentication does not work if TACACS+ is also used as an authentication mechanism. • Before you can enable local user authentication, you must define at least one username. • Local user accounts and passwords must be fewer than 65 characters and can consist of any alphanumeric characters. Local user accounts must contain at least one alphabetic character. Configuring Login Authentication The next two sections describe how to configure login authentication on the switch. 78-15486-01 Catalyst 4500 Series, Catalyst 2948G, Catalyst 2980G Switches Software Configuration Guide-Release 8.1 30-9
