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.
PowerConnect(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 Dell PowerConnect 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.
