Configuring RADIUS security
26
You enable RADIUS 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 radius
Syntax: aaa authorization commands <privilege-level> default radius | tacacs+ | none
The <privilege-level> parameter can be one of the following:
• 0 – Authorization is performed (that is, the device looks at the command list) 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
RADIUS 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.
NOTE
Since RADIUS command authorization relies on the command list supplied by the RADIUS server
during authentication, you cannot perform RADIUS authorization without RADIUS authentication.
Command authorization and accounting for console commands
The device 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.
PowerConnect(config)# enable aaa console
Syntax: enable aaa console
CAUTION
If you have previously configured the device to perform command authorization using a RADIUS
server, entering the enable aaa console command may prevent the execution of any subsequent
commands entered on the console.
This happens because RADIUS command authorization requires a list of allowable commands
from the RADIUS server. This list is obtained during RADIUS authentication. For console sessions,
RADIUS authentication is performed only if you have configured Enable authentication and
specified RADIUS as the authentication method (for example, with the aaa authentication enable
default radius command). If RADIUS authentication is never performed, the list of allowable
commands is never obtained from the RADIUS server. Consequently, there would be no allowable
commands on the console.
