Brocade Communications Systems 6650 manual Configuring command authorization

TACACS and TACACS+ security

Example

user=bob {

default service = permit member admin

#Global password

global = cleartext "cat" service = exec {

foundry-privlvl = 4 privlvl = 15

}

}

In this example, the user would be granted a privilege level of 4 (port-config level). The privlvl = 15 A-V pair is ignored by the Brocade device.

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 Brocade device 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 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 tacacs+

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

The privilege-levelparameter can be one of the following:

•0 – Authorization is performed 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

TACACS+ command authorization can be performed only for commands entered from Telnet or SSH sessions, or from the console.

TACACS+ command authorization is not performed for the following commands:

•At all levels: exit, logout, end, and quit.

•At the Privileged EXEC level: enable or enable text, where text is the password configured for the Super User privilege level.

If configured, command accounting is performed for these commands.

AAA support for console commands

AAA support for commands entered at the console includes the following:

•Login prompt that uses AAA authentication, using authentication-method lists
