RADIUS security
Entering privileged EXEC mode after a Telnet or SSH login
By default, a user enters User EXEC mode after a successful login through Telnet or SSH.
Optionally, you can configure the device so that a user enters Privileged EXEC mode after a Telnet
or SSH login. To do this, use the following command.
Brocade(config)# aaa authentication login privilege-mode
Syntax: aaa authentication login privilege-mode
The user privilege level is based on the privilege level granted during login.
Configuring enable authentication to prompt for password only
If Enable authentication is configured on the device, when a user attempts to gain Super User
access to the Privileged EXEC and CONFIG levels of the CLI, by default he or she is prompted for a
username and password. You can configure the Brocade device to prompt only for a password. The
device uses the username entered at login, if one is available. If no username was entered at login,
the device prompts for both username and password.
To configure the Brocade device to prompt only for a password when a user attempts to gain Super
User access to the Privileged EXEC and CONFIG levels of the CLI.
Brocade(config)# aaa authentication enable implicit-user
Syntax: [no] aaa authentication enable implicit-user
RADIUS authorization
Brocade devices support RADIUS authorization for controlling access to management functions in
the CLI. Two kinds of RADIUS authorization are supported:
•Exec authorization determines a user privilege level when they are authenticated
•Command authorization consults a RADIUS server to get authorization for commands entered
by the user
Configuring EXEC authorization
When RADIUS EXEC authorization is performed, the Brocade device consults a RADIUS server to
determine the privilege level of the authenticated user. To configure RADIUS EXEC authorization on
the Brocade device, enter the following command.
Brocade(config)# aaa authorization exec default radius
Syntax: aaa authorization exec default radius | none
If you specify none, or omit the aaa authorization exec command from the device configuration, no
EXEC authorization is performed.
