Configuring TACACS/TACACS+ security
TACACS/TACACS+ configuration considerations
• You must deploy at least one TACACS/TACACS+ server in your network.
• Devices support authentication using up to eight TACACS/TACACS+ servers. The device tries to
use the servers in the order you add them to the device configuration.
• You can select only one primary authentication method for each type of access to a device (CLI
through Telnet, CLI Privileged EXEC and CONFIG levels). For example, you can select TACACS+
as the primary authentication method for Telnet CLI access, but you cannot also select RADIUS
authentication as a primary method for the same type of access. However, you can configure
backup authentication methods for each access type.
• You can configure the device to authenticate using a TACACS or TACACS+ server, not both.
TACACS configuration procedure
Follow the procedure given below for TACACS configurations.
1. Identify TACACS servers. Refer to “Identifying the TACACS/TACACS+ servers” on page 90.
2. Set optional parameters. Refer to “Setting optional TACACS/TACACS+ parameters” on page 91.
3. Configure authentication-method lists. Refer to “Configuring authentication-method lists for
TACACS/TACACS+” on page 92.
TACACS+ configuration procedure
Follow the procedure given below for TACACS+ configurations.
1. Identify TACACS+ servers. Refer to “Identifying the TACACS/TACACS+ servers” on page 90.
2. Set optional parameters. Refer to “Setting optional TACACS/TACACS+ parameters” on page 91.
3. Configure authentication-method lists. Refer to “Configuring authentication-method lists for
TACACS/TACACS+” on page 92.
4. Optionally configure TACACS+ authorization. Refer to “Configuring TACACS+ authorization” on
page 94.
5. Optionally configure TACACS+ accounting. Refer to “Configuring TACACS+ accounting” on
page 97.
Enabling TACACS
TACACS is disabled by default. To configure TACACS/TACACS+ authentication parameters, you must
enable TACACS by entering the following command.
TurboIron(config)#enable snmp config-tacacs
Syntax: [no] enable snmp <config-radius | config-tacacs>
The <config-radius> parameter specifies the RADIUS configuration mode. RADIUS is disabled by
default.
The <config-tacacs> parameter specifies the TACACS configuration mode. TACACS is disabled by
default.
