Chapter 1 Login Commands
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.
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.

Description
Use the auto-execute command command
to set the command that is executed automatically after a user logs in.
Use the undo auto-execute command
command to disable the specified command from being automatically executed.
Execute these two commands in VTY user
interface view only.
Normally, the telnet command is
specified to be executed automatically to enable the user to Telnet to a
specific network device automatically.
By default, no command is automatically
executed.
Caution:
l
The auto-execute command command may
cause you unable to perform common configuration in the user interface, so use
it with caution.
l
Before executing the auto-execute command
command and save your configuration, make sure you can log into the switch in
other modes and cancel the configuration.

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.)

lock
View
User view
Parameter
None
Description
Use the lock command to lock the
current user interface to prevent unauthorized operations in the user interface.
After you issue this command, the system prompts you to enter a password
containing 1 to 16 characters. After you confirm the password, the current user
interface is locked.
You can unlock the user interface by
entering the correct password. If you set a password containing more than 16
characters, the system matches only the first 16 characters of the password
entered for unlocking the user interface. That is, the system unlocks the user
interface as long as the first 16 characters of the password entered are
correct.

Parameter
cipher:
Specifies to display the local password in encrypted text when you display the
current configuration.
simple:
Specifies to display the local password in plain text when you display the
current configuration.
password: Password.
The password must be in plain text if you specify the simple keyword in the
set authentication password command. If you specify the cipher
keyword, the password can be in either encrypted text or plain text. When you
enter the password in plain text containing up to 16 characters (such as 123),
the system converts the password to the corresponding 24-character encrypted
password (such as !TP<\*EMUHL,408`W7TH!Q!!). Make sure you are aware of the
corresponding plain password if you enter the password in ciphered text (such
as !TP<\*EMUHL,408`W7TH!Q!!).
