2.1 Commands for Controlling Logging in Users
Chapter 1 Login Commands
1.1 Login Commands
1.1.1 authentication-mode
Syntax
authentication-mode { password | scheme [ command-authorization ] | none }
View
User interface view
Parameter
password: Authenticates users using the local password.
scheme: Authenticates users locally or remotely using usernames and passwords.
command-authorization: Performs command authorization on TACACS authentication server.
none: Does not authenticate users.
Description
Use the authentication-mode command to specify the authentication mode.
l If you specify the password keyword to authenticate users using the local password, remember to set the local password using the set authentication password { cipher | simple } password command.
l If you specify the scheme keyword to authenticate users locally or remotely using usernames and passwords, the actual authentication mode, that is, local or remote, depends on other related configuration.
l If this command is executed with the command-authorization keyword specified, authorization is performed on the TACACS server whenever you attempt to execute a command, and the command can be executed only when you pass the authorization. Normally, a TACACS server contains a list of the commands available to different users.
If you specify to perform local authentication when a user logs in through the Console port, a user can log into the switch with the password not configured. But for a VTY user interface, a password is needed for a user to log into the switch through it under the same circumstance.
By default, users logging in through the Console port are not authenticated, whereas modem users and Telnet users are authenticated.
& Note:
To improve security and avoid malicious attack to the unused SOCKETs, TCP 23 and TCP 22, ports for Telnet and SSH services respectively, will be enabled or disabled after corresponding configurations.
l If the authentication mode is none, TCP 23 will be enabled, and TCP 22 will be disabled.
l If the authentication mode is password, and the corresponding password has been set, TCP 23 will be enabled, and TCP 22 will be disabled.
l If the authentication mode is scheme, there are three scenarios: when the supported protocol is specified as telnet, TCP 23 will be enabled; when the supported protocol is specified as ssh, TCP 22 will be enabled; when the supported protocol is specified as all, both the TCP 23 and TCP 22 port will be enabled.
Example
# Configure to authenticate users using the local password on the AUX interface.

1.1.10 header
Syntax
header [ incoming | login | shell ] text
undo header { incoming | login | shell }
View
System view
Parameter
incoming: Sets the login banner for users that log in through modems. If you specify to authenticate login users, the banner appears after a user passes the authentication. (The session does not appear in this case.)
login: Sets the login banner. The banner set by this keyword is valid only when users are authenticated before they log into the switch and appears while the switch prompts for user name and password.
shell: Sets the session banner, which appears after a session is established. If you specify to authenticate login users, the banner appears after a user passes the authentication.
text: Banner to be displayed. If no keyword is specified, this argument is the login banner. You can provide this argument in two ways. One is to enter the banner in the same line as the command (A command line can accept up to 254 characters.) The other is to enter the banner in multiple lines (you can start a new line by pressing <Enter>,) where you can enter a banner that can contain up to 2000 characters (including the invisible characters). Note that the first character is the beginning character and the end character of the banner. After entering the end character, you can press <Enter> to exit the interaction.
Description
Use the header command to set the banners that are displayed when a user logs into a switch. The login banner is displayed on the terminal when the connection is established. And the session banner is displayed on the terminal if a user successfully logs in.
Use the undo header command to disable displaying a specific banner or all banners.
Note that if you specify any one of the three keywords without providing the text argument, the specified keyword will be regarded as the login information.
You can specify the banner in the following three ways, each of which requires that the first character and the last character of the banner be the same.
l Enter the banner in multiple lines. If you only type one character in the first line of a banner, the character and the last character do not act as part of the banner. The following gives an example of this way.
[H3C] header shell 0
Input banner text, and quit with the character '0'.
Welcome!0
When you log in the next time, “Welcome!” is displayed as the banner. The beginning character and the end character (character 0) do not appear.
l Enter the banner in multiple lines. If you type multiple characters in the first line of a banner and the beginning and the end characters of the banner in this line are not the same, the beginning character is part of the banner. The following is an example.
[H3C] header shell hello
Input banner text, and quit with the character 'h'.
my friend !
h
When you log in the next time, “hello” and “my friend !“ is displayed respectively in two lines as the banner. The beginning character “h” appears in the banner.
l Enter the banner in a single line. You can also specify the banner in a single line. In this case, the banner does contain the beginning and the end character. The following is an example.
[H3C] header shell 0welcome,my friend!0
When you log in the next time, “welcome, my friend!” is displayed as the banner.
Example
# Set the session banner.
Option 1: Enter the banner in the same line as the command.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] header shell %SHELL: Hello! Welcome%
(Make sure the beginning and end characters of the banner are the same.)
When you log in the next time, the session banner appears on the terminal as the following:
[H3C] quit
<H3C> quit
Please press ENTER
SHELL: Hello! Welcome
(The beginning and end characters of the banner are not displayed.)
<H3C>
Option 2: Enter the banner in multiple lines.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] header shell %SHELL:
(Following appears after you press <Enter>:)
Input banner text, and quit with the character '%'.
Continue entering the banner and end the banner with the character identical with the beginning character of the banner.
Hello! Welcome %
(Press <Enter>.)
[H3C]
When you log in the next time, the session banner appears on the terminal as the following:
[H3C] quit
<H3C> quit
Please press ENTER
%SHELL:
(Note that the beginning character of the banner appears.)
Hello! Welcome
