Logging in through the console port locally
You can connect a terminal to the console port of the device to log in and manage the device, as
shown in Figure 3. For the login procedure, see "Logging in through the console port for the first
device access."
Figure 3 Logging in through the console port
By default, console login is enabled and does not require authentication. To improve device security,
configure password or scheme authentication and assign user roles immediately after you log in to
the device for the first time.
To configure console login, perform the following tasks:
(Required.) Configuring login authentication:
• Disabling authentication for console login
• Configuring password authentication for console login
• Configuring scheme authentication for console login
Configure one authentication mode as
required.
In FIPS mode, only the scheme
authentication mode is supported.
(Optional.) Configuring common AUX line settings N/A
Console login configuration changes do not take effect for current online users. They take effect only
for new login users.
Before using multiple devices to form an IRF fabric, enter AUX line class view on each device and
perform the following tasks:

A setting in user line view is applied only to the
user line. A setting in user line class view is
applied to all user lines of the class.
A non-
default setting in either view takes
precedence over a default setting in the other
view. A non-
default setting in user line view
takes precedence over a non-default setting in
user line class view.
A
setting in user line view takes effect
immediately and affects the online user. A

online users and takes effect only for new login
users.
