Brocade Communications Systems 6650 manual Configuring command authorization

RADIUS security

NOTE

If the aaa authorization exec default radius command exists in the configuration, following successful authentication the device assigns the user the privilege level specified by the foundry-privilege-level attribute received from the RADIUS server. If the aaa authorization exec default radius command does not exist in the configuration, then the value in the foundry-privilege-level attribute is ignored, and the user is granted Super User access.

Also note that in order for the aaa authorization exec default radius command to work, either the

aaaauthentication enable default radius command, or the aaa authentication login privilege-mode command must also exist in the configuration.

Configuring command authorization

When RADIUS command authorization is enabled, the Brocade device consults the list of commands supplied by the RADIUS server during authentication to determine whether a user can execute a command he or she has entered.

You enable RADIUS command authorization by specifying a privilege level whose commands require authorization. For example, to configure the Brocade 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.

Brocade(config)# aaa authorization commands 0 default radius

Syntax: aaa authorization commands privilege-leveldefault radius tacacs+ none

The privilege-levelparameter can be one of the following:

•0 – Authorization is performed (that is, the Brocade 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.

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 Brocade 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.

Brocade(config)# enable aaa console
