Defaults Command Modes Command History Usage Information Related Commands • tacacs+ - use the TACACS+ server(s) configured with the tacacs-server host command. ... method4 (OPTIONAL) Enter up to four additional methods. In the event of a "no response" from the first method, FTOS applies the next configured method (up to four configured methods). Not configured (that is, no authentication is performed). CONFIGURATION Version 8.3.11.1 Version 8.3.7.0 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.2.1.0 Introduced on the Z9000. Introduced on the S4810. Introduced on the S-Series. Introduced on the C-Series. Introduced on the E-Series. By default, the locally configured username password is used. If you configure aaa authentication login default, FTOS uses the methods defined by this command for login instead. Methods configured with the aaa authentication login command are evaluated in the order they are configured. If users encounter an error with the first method listed, FTOS applies the next method configured. If users fail the first method listed, no other methods are applied. The only exception is the local method. If the user's name is not listed in the local database, the next method is applied. If the correct user name/password combination are not entered, the user is not allowed access to the switch. NOTE: If authentication fails using the primary method, FTOS employs the second method (or third method, if necessary) automatically. For example, if the TACACS+ server is reachable, but the server key is invalid, FTOS proceeds to the next authentication method. The TACACS+ is incorrect, but the user is still authenticated by the secondary method. After configuring the aaa authentication login command, configure the login authentication command to enable the authentication scheme on terminal lines. Connections to the SSH server work with the following login mechanisms: local, radius, and tacacs. login authentication - enables AAA login authentication on the terminal lines. password - creates a password. radius-server host - specifies a RADIUS server host. tacacs-server host - specifies a TACACS+ server host. 1295

tacacs+

- use the TACACS+ server(s) configured with the

tacacs-server host

command.

(OPTIONAL) Enter up to four additional methods. In the event of a “no

response” from the first method, FTOS applies the next configured

method (up to four configured methods).

Defaults

Not configured (that is, no authentication is performed).

Usage

Information

By default, the locally configured username password is used. If you configure

aaa

authentication login default

, FTOS uses the methods defined by this command

for login instead.

Methods configured with the

aaa authentication login

command are evaluated in

the order they are configured. If users encounter an error with the first method listed, FTOS

applies the next method configured. If users fail the first method listed, no other methods are

applied. The only exception is the local method. If the user’s name is not listed in the local

database, the next method is applied. If the correct user name/password combination are not

entered, the user is not allowed access to the switch.

NOTE:

If authentication fails using the primary method, FTOS employs the second method

(or third method, if necessary) automatically. For example, if the TACACS+ server is

reachable, but the server key is invalid, FTOS proceeds to the next authentication method.

The TACACS+ is incorrect, but the user is still authenticated by the secondary method.

After configuring the

aaa authentication login

command, configure the

authentication

command to enable the authentication scheme on terminal lines.

Connections to the SSH server work with the following login mechanisms: local, radius, and

tacacs.

Commands

– enables AAA login authentication on the terminal lines.

password

– creates a password.

radius-server host

– specifies a RADIUS server host.

tacacs-server host

– specifies a TACACS+ server host.
