Console Port Login Configuration with Authentication Mode Being None 17
Note that the command level available to users logging into a switch depends on
both the authentication-mode { password | scheme | none } command and the
user privilege level level command, as listed in Table 15.
Configuration Example Network requirements
Assume that you are a level 3 VTY user and want to perform the following
configuration for users logging in through the Console port:
■ Do not authenticate users logging in through the Console port.
■ Commands of level 2 are available to users logging into the AUX user interface.
■ The baud rate of the Console port is 19,200 bps.
■ The screen can contain up to 30 lines.
■ The history command buffer can contain up to 20 commands.
■ The timeout time of the AUX user interface is 6 minutes.
