Configuring TACACS/TACACS+ security
26
You enable TACACS+ command authorization by specifying a privilege level whose commands
require authorization. For example, to configure the device to perform authorization for the
commands available at the Super User privilege level (that is, all commands on the device), enter
the following command.
PowerConnect(config)# aaa authorization commands 0 default tacacs+
Syntax: aaa authorization commands <privilege-level> default tacacs+ | radius | none
The <privilege-level> parameter can be one of the following:
• 0 – Authorization is performed for commands available at the Super User level (all commands)
• 4 – Authorization is performed for commands available at the Port Configuration level
(port-config and read-only commands)
• 5 – Authorization is performed for commands available at the Read Only level (read-only
commands)
NOTE
TACACS+ command authorization can be performed only for commands entered from Telnet or SSH
sessions, or from the console. No authorization is performed for commands entered at the Brocade
Network Advisor.
TACACS+ command authorization is not performed for the following commands:
• At all levels: exit, logout, end, and quit.
• At the Privileged EXEC level: enable or enable <text>, where <text> is the password configured
for the Super User privilege level.
If configured, command accounting is performed for these commands.
AAA support for console commands
AAA support for commands entered at the console includes the following:
• Login prompt that uses AAA authentication, using authentication-method Lists
• Exec Authorization
• Exec Accounting
• Command authorization
• Command accounting
• System Accounting
To enable AAA support for commands entered at the console, enter the following command.
PowerConnect(config)# enable aaa console
Syntax: [no] enable aaa console
Configuring TACACS+ accounting
Devices support TACACS+ accounting for recording information about user activity and system
events. When you configure TACACS+ accounting on a device, information is sent to a TACACS+
accounting server when specified events occur, such as when a user logs into the device or the
system is rebooted.
