Configuring TACACS/TACACS+ security
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 device 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.
TurboIron(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)
Configuring TACACS+ accounting for system events
You can configure TACACS+ accounting to record when system events occur on the device. System
events include rebooting and when changes to the active configuration are made.
The following command causes an Accounting Start packet to be sent to the TACACS+ accounting
server when a system event occurs, and a Accounting Stop packet to be sent when the system
event is completed.
TurboIron(config)#aaa accounting system default start-stop tacacs+
Syntax: aaa accounting system default start-stop radius | tacacs+ | none
Configuring an interface as the source for all
TACACS/TACACS+ packets
You can designate the lowest-numbered IP address configured an Ethernet port, loopback
interface, or virtual interface as the source IP address for all TACACS/TACACS+ packets from the
Layer 3 Switch. Identifying a single source IP address for TACACS/TACACS+ packets provides the
following benefits:
• If your TACACS/TACACS+ server is configured to accept packets only from specific links or IP
addresses, you can use this feature to simplify configuration of the TACACS/TACACS+ server by
configuring the device to always send the TACACS/TACACS+ packets from the same link or
source address.
