Configuring RADIUS accounting for CLI commands
You can configure RADIUS accounting for CLI commands by specifying a privilege level whose
commands require accounting. For example, to configure the Dell PowerConnect device to perform
RADIUS accounting for the commands available at the Super User privilege level (that is; all
commands on the device), enter the following command.
PowerConnect(config)#aaa accounting commands 0 default start-stop radius
An Accounting Start packet is sent to the RADIUS 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 RADIUS accounting for system events
You can configure RADIUS accounting to record when system events occur on the Dell
PowerConnect 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 RADIUS accounting
server when a system event occurs, and a Accounting Stop packet to be sent when the system
event is completed.
PowerConnect(config)#aaa accounting system default start-stop radius
Syntax: aaa accounting system default start-stop radius | tacacs+ | none
Configuring an interface as the source for all
RADIUS 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 RADIUS packets from the Layer 3
Switch. For configuration details, see “Configuring ARP parameters” on page 810.
Displaying RADIUS configuration information
The show aaa command displays information about all TACACS/TACACS+ and RADIUS servers
identified on the device.
