Chapter 1 Commands for Logging into an
Ethernet Switch
Syntax
activation-key character
undo activation-key
View
User interface view
Parameter
character:
Shortcut key for starting terminal sessions, a character or its ASCII decimal
equivalent in the range 0 to 127; or a string of 1 to 3 characters.
Description
Use the activation-key command to
define a shortcut key for starting a terminal session.
Use the undo activation-key command
to restore the default shortcut key.
Use these two commands in the AUX user
interface only.
You can use a single character (or its
corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3
characters to define a shortcut key. In the latter case, the system takes only
the first character to define the shortcut key. For example, if you input an ASCII
code value 97, the system will set the shortcut key to <a>; if you input
the string b@c, the system will set the shortcut key to <b>.
You may use the display
current-configuration command to verify the shortcut key you have defined.
By default, pressing Enter key will
start a terminal session.
Example
# Set the shortcut key for starting
terminal sessions to <s>.
<Sysname> system-view
System View: return to User View with
Ctrl+Z.
[Sysname] user-interface aux 0
[Sysname-ui-aux0] activation-key s
To verify the configuration, do the
following:
# Exit the terminal session on the aux
port, and enter <s> at the prompt of “Please press ENTER”. You
will see the terminal session being started.
[Sysname-ui-aux0] return
<Sysname> quit

authentication-mode { none | password | scheme [ command-authorization
] }
View
User interface view
Parameter
none: Does
not authenticate users.
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.
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 depends on other related configuration. Refer to the AAA-RADIUS-HWTACACS
module of this manual for more.
l
If this command is executed with the command-authorization
keywords 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.
After you specify to perform local password
authentication, when a user logs in through the Console port, a user can log
into the switch even if the password is not configured on the switch. But for a
VTY user interface, a password is needed for a user to log into the switch
through it under the same condition.
By default, users logging in through the
Console port are not authenticated, whereas modem users and Telnet users are
authenticated.
Caution:
For VTY user
interface, if you want to set the login authentication mode to none or password,
you must first verify that the SSH protocol is not supported by the user
interface. Otherwise, your configuration will fail. Refer to section 1.1.17 "protocol inbound”.
Example
# Configure to authenticate users using the
local password.
<Sysname> system-view
System View: return to User View with
Ctrl+Z.

Parameter
text:
Command to be executed automatically.
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.
Use these two commands in the VTY user
interface 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.
Example
# Configure the telnet 10.110.100.1

escape-key {
default | character }
undo escape-key
View
User interface view
Parameter
default:
Restores the default escape key combination <CTL+C>.
character:
Specifies the shortcut key for aborting a task, a single character (or its
corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3
characters.
Description
Use the escape-key command to define
a shortcut key for aborting tasks.
Use the undo escape-key command to
restore the default shortcut key.
You can use a single character (or its
corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3
characters to define a shortcut key. But in fact, only the first character
functions as the shortcut key. For example, if you enter an ASCII value 113,
the system will use its corresponding character <q> as the shortcut key;
if you input the string q@c, the system will use the first letter <q> as
the shortcut key.
By default, you can use <Ctrl+C> to
terminate a task. You can use the display current-configuration command
to verify the shortcut key you have defined.
Example
# Define <Q> as the escape key.
<Sysname> system-view
System View: return to User View with
Ctrl+Z.
[Sysname] user-interface aux 0
[Sysname-ui-aux0] escape-key Q

the type. When the type is AUX, the number is 0; when the type is VTY,
the number ranges from 0 to 4.
l
Absolute user interface index: If you do not
provide the type argument, number indicates absolute user
interface index, which ranges from 0 to 5.
Description
Use the free user-interface command
to clear a specified user interface. If you execute this command, the
corresponding user interface will be disconnected.
Note that the current user interface can
not be cleared.

Syntax
header { incoming | legal | login |
shell | motd } text
undo header { incoming | legal | login |
shell | motd }
View
System view
Parameter
incoming: Login
header, the information output after a Modem user logs in. If authentication is
required, it is prompted after the user passes authentication. In this case, no
shell information is output.
legal: Sets
the authorization banner. If you specify to authenticate login users, the
banner appears before a user passes the authentication.
login: Login
information in case of authentication. It is displayed before the user is
prompted to enter user name and password.
shell: User
conversation established header, the information output after user conversation
has been established. If authentication is required, it is prompted after the
user passes authentication.
motd: Sets
the login banner. If you specify to authenticate login users, the banner
appears before a user passes the authentication but after the legal
banner.
text: Specifies the title text. If you do
not choose any keyword in the command, the system displays the login
information by default. The system supports two types of input modes:
l
One is to input all the text in one line, and
altogether 510 characters, including command key word, can be input. The
beginning character and the end character you input must be the same, but the
two characters are not included in the content of the welcome information.
l
The other is to input all the text in several
lines using the Enter key, and more than 510 characters can be input. And
this input mode falls into the following three types:
1)
Press the Enter key directly at the first
line, and end the setting with %. The % character and the carriage-return
character do not act as part of the banner.
2)
Type a character in the first line of a banner,
then press the Enter key, and end the setting with the character typed
in the first line. The beginning character and the end character do not act as part
of the banner.
3)
Type multiple characters in the first line (the
first and last characters in the line are different), then press Enter, and
then end the setting with the first character of the first line. The first
character of the first line and the end character do not act as part of the
banner.
Description
Using header command, you can
configure to display header when user login. Using undo header command,
you can configure not to display the header.
When the users log in the switch, if a connection
is activated, the login header will be displayed. After the user
successfully logs in the switch, the shell header will be displayed.
Note that if you press the Enter key
after typing any of the three keywords shell, login and incoming
in the command, then what you type after the word header is the contents of the
login information, instead of identifying header type.
You can judge whether the initial character
can be used as the header contents this way:
1)
If there is only one character in the first line
and it is used as the identifier, this initial character pairs with the ending
character and is not the header contents.
2)
If there are many characters in the first line
but the initial and ending characters are different, this initial character
pairs with the ending character and is the header contents.
3)
There are many characters in the first line and
the initial character is identical with the ending character, this initial
character is not the header contents.
Example
# Configure welcome information of user interface.
<Sysname> system-view
System View: return to User View with
Ctrl+Z.
[Sysname] header incoming %
Input banner text, and quit with the
character '%'.
Welcome to incomeing(header incoming)%
[Sysname] header legal %
Input banner text, and quit with the
character '%'.
Welcome to legal (header legal)%
[Sysname] header login %
Input banner text, and quit with the
character '%'.
Welcome to login(header login)%
[Sysname] header motd %
Input banner text, and quit with the
character '%'.
Welcome to motd(header motd)%
[Sysname] header shell %
Input banner text, and quit with the
character '%'.
Welcome to shell(header shell)%
l
In this example, % acts as the beginning/end character
of the text. After the text is displayed, enter the % character to end
the text and quit the header command.
l
As the beginning/end character, the % character
does not act as part of the welcome information.

undo set authentication password
View
User interface view
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. Whether
the password is in encrypted text or plain text depends on the password string
entered. Strings containing up to 16 characters (such as 123) are regarded as
plain text passwords and are converted to the corresponding 24-character
encrypted password (such as !TP<\*EMUHL,408`W7TH!Q!!). A encrypted password
must contain 24 characters and must be in ciphered text (such as !TP<\*EMUHL,408`W7TH!Q!!).
Description
Use the set authentication password
command to set the local password.
Use the undo set authentication password
command to remove the local password.
Note that only plain text passwords are
expected when users are authenticated.
By default, modem
users and Telnet users need to provide their passwords to log in. If no
password is set, the “Login password has not been set !” message
appears on the terminal when users log in.
Example
# Set the local password of VTY 0 to “123”.

Parameter
None
Description
Use the shell command to make
terminal services available for the user interface.
Use the undo shell command to make
terminal services unavailable to the user interface.
By default, terminal services are available
in all user interfaces.
Note the following when using the undo shell
command:
l
This command is available in all user interfaces
except the AUX user interface, because the AUX port (also the Console) is exclusively
used for configuring the switch.
l
This command is unavailable in the current user
interface.
l
This command prompts for confirmation when being
executed in any valid user interface.
Example
# Log into user interface 0 and make
terminal services unavailable in VTY 0 through VTY 4.
<Sysname> system-view
System View: return to User View with
Ctrl+Z.

Parameter
speed-value:
Transmission speed (in bps). This argument can be 300, 600, 1200, 2400, 4800, 9600,
19,200, 38,400, 57,600, 115,200 and defaults to 9,600.
Description
Use the speed command to set the
transmission speed of the user interface.
Use the undo speed command to revert
to the default transmission speed.
Use these two commands in the AUX user interface view only.
After you use the speed
command to configure the transmission speed of the AUX user interface, you must
change the corresponding configuration of the terminal emulation program
running on the PC, to keep the configuration consistent with that on the
switch.
Example
# Set the transmission speed of the AUX
user interface to 9,600 bps.

Parameter
string: System
name of the switch. This argument can contain 1 to 30 characters and defaults
to “H3C”.
Description
Use the sysname command to set a system
name for the switch.
Use the undo sysname command to
revert to the default system name.
The CLI prompt reflects the system name of
a switch. For example, if the system name of a switch is “H3C”,
then the prompt of user view is <H3C>.
Example
# Set the system name of the switch to “ABC”.
<Sysname> system-view

Parameter
hostname:
Host name of the remote switch. You can use the ip host command to
assign a host name to a switch.
Ipv4-address:
Specifies a Telnet server’s IPv4 address.
ipv6-address:
Specifies a Telnet server’s IPv6 address.
-i interface-type
interface-number: Specifies the type and number of an outgoing interface.
It is required when the destination address is a link local address.
service-port:
TCP port number of the port that provides Telnet service on the switch. This
argument ranges from 0 to 65,535. The default TCP port number is 23.
Description
Use the telnet command to Telnet to
another switch from the current switch to manage the former remotely. You can
terminate a Telnet connection by pressing <Ctrl + K>.
Related command: display tcp status.
Example
# Telnet to the switch with the host name
of Sysname2 and IP address of 129.102.0.1 from the current switch (with the
host name of Sysname1).
<Sysname1> telnet 129.102.0.1
