Configuring TACACS or TACACS+ security
2
If configured, command accounting is performed for these commands.
Command authorization and accounting for console commands
The ServerIron supports command authorization and command accounting for CLI commands
entered at the console. To configure the device to perform command authorization and command
accounting for console commands, enter the following.
ServerIronADX(config)# enable aaa console
Syntax: enable aaa console
Configuring TACACS+ accounting
ServerIrons support TACACS+ accounting for recording information about user activity and system
events. When you configure TACACS+ accounting on a ServerIron, 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.
Configuring TACACS+ accounting for Telnet or SSH (shell) access
To send an Accounting Start packet to the TACACS+ accounting server when an authenticated user
establishes a Telnet or SSH session on the ServerIron, and an Accounting Stop packet when the
user logs out.
ServerIronADX(config)# aaa accounting exec default start-stop tacacs+
Syntax: aaa accounting exec default start-stop radius | tacacs+ | none
Configuring TACACS+ accounting for CLI commands
You can configure TACACS+ accounting for CLI commands by specifying a privilege level whose
commands require accounting. For example, to configure the ServerIron to perform TACACS+
accounting for the commands available at the Super User privilege level (that is; all commands on
the device), enter the following command.
ServerIronADX(config)# aaa accounting commands 0 default start-stop tacacs+
An Accounting Start packet is sent to the TACACS+ accounting server when a user enters a
command, and an Accounting Stop packet is sent when the service provided by the command is
completed.
NOTE
If authorization is enabled, and the command requires authorization, then authorization is
performed before accounting takes place. If authorization fails for the command, no accounting
takes place.
Syntax: aaa accounting commands <privilege-level> default start-stop radius | tacacs+ | none
The <privilege-level> parameter can be one of the following:
• 0 – Records commands available at the Super User level (all commands)
• 4 – Records commands available at the Port Configuration level (port-config and read-only
commands)
• 5 – Records commands available at the Read Only level (read-only commands)
