Configuring TACACS and TACACS+ security
If the TACACS+ server has no A-V pair configured for the Exec service, the default privilege level of 5
(read-only) is used.
Configuring command authorization
When TACACS+ command authorization is enabled, the BigIron RX consults a TACACS+ server to
get authorization for commands entered by the user.
You enable TACACS+ command authorization by specifying a privilege level whose commands
require authorization. For example, to configure the BigIron RX to perform authorization for the
commands available at the Super User privilege level (that is, all commands on the device), enter
the following command.
BigIron RX(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:
•

sessions, or from the console. No authorization is performed for commands entered at the Web
Management Interface or IronView Network Manager .

If configured, command accounting is performed for these commands.
