Configuring the CLI
CLI enables you to interact with your device by typing text commands. At the CLI, instruct your device to perform a given task by typing a text command and then pressing Enter. Compared with the graphical user interface (GUI) where you can use a mouse to perform configurations, the CLI allows you to enter more information in one command line.
Figure 1 CLI example
Entering the CLI
HP devices provide multiple methods for entering the CLI, such as through the console port, through Telnet, or through SSH. For more information, see “Login methods.”
1
Command conventions
p
Command conventions help you understand command meanings. Commands in HP product manuals comply with the conventions listed in Table 1.
Table 1 Command conventions
Convention Descri
Boldface Bold text represents commands and keywords you enter literally as shown.
Italic Italic text represents arguments you replace with actual values.
[ ] Square brackets enclose syntax choices (keywords or arguments) that are optional.
{ x | y | ... }
[ x | y | ... ]
{ x | y | ... } *
[ x | y | ... ] *
&<1-n>
# A line that starts with a pound (#) sign is comments.
Braces enclose a set of required syntax choices separated by vertical bars, from which you select one.
Square brackets enclose a set of optional syntax choices separated by vertical bars, from which you select one or none.
Asterisk marked braces enclose a set of required syntax choices separated by vertical bars, from which you select at least one.
Asterisk marked square brackets enclose optional syntax choices separated by vertical bars, from which you select one choice, multiple choices, or none.
The argument or keyword and argument combination before the ampersand (&) sign can be entered 1 to n times.
tion
NOTE:
The keywords of HP command lines are case insensitive.
Use clock datetime time date as an example to understand the meaning of the command line parameters according to Figure 2.
Figure 2 Read command line parameters
For example, enter the following at the CLI of your device and press Enter to set the device system time to 10 o’clock 30 minutes 20 seconds, February 23, 2010.
<sysname> clock datetime 10:30:20 2/23/2010
Read any command that is more complicated by referring to Table 1.
2
Undo form of a command
The undo form of a command restores the default, disables a function, or removes a configuration.
Almost all configuration commands have an undo form. For example, info-center enable enables the information center and undo info-center enable disables the information center.
CLI view description
Commands are grouped into different classes by function. To use a command, you must enter the class view of the command.
CLI views adopt a hierarchical structure. See Figure 3.
A
ter logging in to the switch, you are in user view. The prompt of user view is <device name>. In user
f view, perform display, debugging, and file management operations, set the system time, restart your device, and perform FTP and Telnet operations.
Enter system view from user view. In system view, configure parameters such as daylight saving time,
banners, and short-cut keys.
From system view, enter different function views. For example, enter interface view to configure interface
parameters, create a VLAN and enter its view, enter user interface view to configure login user attributes, create a local user and enter local user view to configure the password and level of the local user, and enter OSPF view to configure OSPF parameters.
NOTE:
Enter ? in any view to display all commands that can be executed in this view.
Figure 3 Command line views
……

Entering system view
p
When you log in to the device, you automatically enter user view, where <Device name> is displayed. Perform limited operations in user view, for example, display operations, file operations, and Telnet operations.
To perform further configuration for the device, enter system view.
Step Command
1. Enter system view from user
view.
Exiting the current view
The CLI is divided into different command views. Each view has a set of specific commands and defines the effective scope of the commands. The commands available to you at any given time depend on the view you are in.
Follow the step below to exit the current view:
Task Command
1. Return to the parent view from the
current view.
In public key code view, use public-key-code end to return to the parent view (public key view).
In public key view, use peer-public-key end to return to system view.
system-view
quit

In user view, quit stops the current connection between the terminal and the device.
Returning to user view
This feature allows you to return to user view from any other view, without using quit command repeatedly. Alternately, press Ctrl+Z to return to user view from the current view.
Follow the step below to exit to user view:
Ste
Command
1. Return to user view.
return
Remarks
Required.
Available in any view except user view.

Using online help
Enter a question mark (?) to obtain online help. See the following examples.
1. Enter ? in any view to display all commands available in this view and brief descriptions of these
commands. For example:
<sysname> ? User view commands: archive Specify archive settings backup Backup next startup-configuration file to TFTP server boot-loader Set boot loader bootrom Update/read/backup/restore bootrom cd Change current directory
…Omitted…
2. Enter part of a command and a ? separated by a space.
If ? is at the position of a keyword, the CLI displays all possible keywords with a brief description for each keyword. For example:
<sysname> terminal ? debugging Send debug information to terminal logging Send log information to terminal monitor Send information output to current terminal trapping Send trap information to terminal
If ? is at the position of an argument, the CLI displays a description about this argument. For example:
<sysname> system-view [sysname] interface vlan-interface ? <1-4094> VLAN interface [sysname] interface vlan-interface 1 ? <cr> [sysname] interface vlan-interface 1
The string <cr> indicates that the command is a complete command. Execute the command by pressing Enter.
3. Enter an incomplete character string followed by a ?. The CLI displays all commands starting with the
entered character(s).
<sysname> c? cd cfd clock cluster copy <sysname> display cl? clipboard clock cluster

Editing command lines
Table 2 lists some shortcut keys you can use to edit command lines.
Table 2 Editing functions
Ke
Function
Common keys
Backspace
Left arrow key or Ctrl+B The cursor moves one character space to the left.
Right arrow key or Ctrl+F The cursor moves one character space to the right.
Tab
If the edit buffer is not full, pressing a common key inserts the character at the position of the cursor and moves the cursor to the right.
Deletes the character to the left of the cursor and moves the cursor back one character.
If you press Tab after entering part of a keyword, the system automatically completes the keyword:
If finding a unique match, the system substitutes the complete keyword for
the incomplete one and displays it in the next line.
If there is more than one match, press Tab repeatedly to view in cycles all
keywords starting with the character string you entered.
If there is no match, the system does not modify the incomplete keyword
and displays it again in the next line.
Entering incomplete keywords
Enter a command comprising incomplete keywords that uniquely identify the complete command.
In user view, for example, commands starting with an s include startup saved-configuration and system-view.
To enter system view, enter sy.
To set the configuration file for next startup, enter st s.
Press Tab to have an incomplete keyword automatically completed.
Configuring command aliases
The command alias function allows you to replace the first keyword of a command with your preferred keyword. For example, if you configure show as the replacement for the display keyword, then to run display xx, enter the command alias show xx.
The following guidelines apply when configuring a command alias:
Define and use a command alias. The command is not restored in its alias format.
When you define a command alias, the cmdkey and alias arguments must be in their complete form.
When you enter an incomplete keyword that partially matches both a defined alias and the keyword of
a command, the alias takes effect. To execute the command whose keyword partially matches your entry, enter the complete keyword. When you enter a character string that partially matches multiple aliases, the system gives you prompts.
6
If you press Tab after you enter the keyword of an alias, the original format of the keyword is displayed.
p
Replace only the first keyword of a non-undo command instead of the complete command; and replace
only the second keyword of undo commands.
To configure command aliases:

% Wrong parameter found at '^' position. Wrong parameters
Using command history
The CLI automatically saves the commands recently used in the history command buffer. Access and execute them again.
Accessing history commands
Task Command
Display history commands.
Display the previous history command.
Display the next history command.
NOTE:
Use arrow keys to access history commands in Windows 200X and XP Terminal or Telnet. However, the up and down arrow keys are invalid in Windows 9X HyperTerminal, because they are defined differently. Use Ctrl+P or Ctrl+N instead.
The commands saved in the history command buffer are in the same format in which you entered the
commands. If you enter an incomplete command, the command saved in the history command buffer is also an incomplete one.
If you execute the same command repeatedly, the switch saves only the earliest record. However, if you
execute the same command in different formats, the system saves them as different commands. For example, if you run display cu repeatedly, the system saves only one command in the history command buffer. If you execute the command in the format of display cu and display current-configuration respectively, the system saves them as two commands.
display history­command

Filtering output information
Use regular expressions in display commands to filter output information.
Remarks
Required
By default, a login user uses the settings of the screen-length. The default settings of the screen-length command are: multiple-screen display is enabled and up to 24 lines are displayed on the next screen.
This command is executed in user view, and takes effect for the current user only. When the user re-logs into the switch, the default configuration is restored.
The following methods are available for filtering output information:
Enter the begin, exclude, or include keyword plus a regular expression in the display to filter the output
information.
When the system displays the output information in multiple screens, use the slash (/), hyphen (-), or plus
(+) with a regular expression to filter subsequent output information. The slash character (/) equals the keyword begin, the character hyphen (-) equals the keyword exclude, and the character plus (+) equals the keyword include.
The following definitions apply to the begin, exclude, and include keywords:
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
11
A regular expression is a case-sensitive string of 1 to 256 characters. It supports the following special
g
characters.
Character Meanin
^string
string$
.
*
+
|
_
Starting sign. string appears only at the beginning of a line.
Ending sign. string appears only at the end of a line.
Matches any single character, such as a single character, a special character, and a blank.
Matches the preceding character or character group zero or multiple times.
Matches the preceding character or character group one or multiple times
Matches the preceding or succeeding character string
If it is at t he beg i nning or t he end of a regular expression, it equals ^ or $. In other cases, it equals comma, space, round bracket, or curly bracket.
Remarks
For example, regular expression “^user” only matches a string beginning with “user," not “Auser."
For example, regular expression "user$” only matches a string ending with “user," not “userA."
For example, “.s” matches “as” and “bs."
For example, “zo*” matches “z” and “zoo”; “(zo)*” matches “zo” and “zozo."
For example, “zo+” matches “zo” and “zoo," but not “z."
For example, “def|int” only matches a character string containing “def” or “int."
For example, “a_b” matches “a b” or “a(b”; “_ab” only matches a line starting with “ab”; “ab_” only matches a line ending with “ab."
-
[ ]
()
\index
It connects two values (the smaller one before it and the bigger one after it) to indicate a range together with [ ].
Matches a single character contained within the brackets.
A character group. It is usually used with “+” or “*."
Repeats the character string specified by the index. A character string refers to the string within () before \. index refers to the sequence number (starting from 1 from left to right) of the character group before \. If only one character group appears before \, index can only be 1; if n character groups appear before index, index can be any integer from 1 to n.
For example, “1-9” means 1 to 9 (inclusive); “a-h” means a to h (inclusive).
For example, [16A] matches a string containing any character among 1, 6, and A; [1-36A] matches a string containing any character among 1, 2, 3, 6, and A (- is a hyphen).
“]” can be matched as a common character only when it is put at the beginning of characters within the brackets, for example [ ]string]. There is no such limit on “[."
For example, (123A) means a character group “123A”; “408(12)+” matches 40812 or
408121212. But it does not match 408.
For example, (string)\1 repeats string, and a matching string must contain stringstring. (string1)(string2)\2 repeats string2, and a matching string must contain string1string2string2. (string1)(string2)\1\2 repeats string1 and string2 respectively, and a matching string must contain string1string2string1string2.
12
Character Meaning Remarks
For example, [^16A] means to match a string containing any character except 1, 6 or A, and the
[^]
Matches a single character not contained within the brackets.
matching string can also contain 1, 6 or A, but cannot contain these three characters only. For example, [^16A] matches “abc” and “m16," but not 1, 16, or 16A.
\<string
string\>
Matches a character string starting with string.
Matches a character string ending with string.
Matches character1character2.
\bcharacter2
character1 can be any character except number, letter or underline, and \b equals [^A-Za-z0-9_].
Matches a string containing
\Bcharacter
character and no space is allowed before character.
Matches character1character2.
character1\w
character2 must be a number, letter, or underline, and \w equals [^A-Za-z0-9_].
\W Equals \b.
Escape character. If a special
\
character listed in this table follows \, the specific meaning of the character is removed.
For example, “\<do” matches word “domain” and string “doa."
For example, “do\>” matches word “undo” and string “abcdo."
For example, “\ba” matches “-a” with “-“ being character1, and “a” being character2, but it does not match “2a” or “ba."
For example, “\Bt” matches “t” in “install," but not “t” in “big top."
For example, “v\w” matches “vlan," with “v” being character1, and “l” being character2. v\w also matches “service," with “i” being character2.
For example, “\Wa” matches “-a," with “-” being character1, and “a” being character2, but does not match “2a” or “ba."
For example, “\\” matches a string containing “\," “\^” matches a string containing “^," and “\\b” matches a string containing “\b."

Configuring user privilege and command levels
To avoid unauthorized access, the switch defines user privilege levels and command levels. User privilege levels correspond to command levels. When a user at a specific privilege level logs in, the user can only use commands at that level, or lower levels.
All commands are categorized into four levels: visit, monitor, system, and manage, and are identified from low to high, respectively by 0 through 3. Table 2 de

By default, commands at this level involve the configuration commands of file system, FTP, TFTP, Xmodem download, user management, level setting, and parameter settings within a system (which are not defined by any protocols or RFCs).
Configuring a user privilege level
A user privilege level can be configured by using AAA authentication parameters or under a user interface.
Configuring user privilege level by using AAA authentication parameters
If the authentication mode of a user interface is scheme, the user privilege level of users logging into the user interface is specified in AAA authentication configuration.

When users Telnet to the switch through VTY 1, they must enter username test and password 12 34 5 678 . After passing the authentication, the users can only use the commands of level 0. If the users want to use commands of levels 0, 1, 2 and 3, the following configuration is required:
[Sysname-luser-test] authorization-attribute level 3
Configuring the user privilege level under a user interface
If the authentication mode of a user interface is scheme, and SSH publickey authentication type (only a
username is needed for this authentication type) is adopted, the user privilege level of users logging into the user interface is the user interface level.
If the authentication mode of a user interface is none or password, the user privilege level of users
logging into the user interface is the user interface level.

Switching user privilege level
g
Users can switch to a different user privilege level temporarily without logging out and terminating the current connection. After the privilege level switch, users can continue to configure the switch without the must re-log in, but the commands that they can execute have changed. For example, if the current user privilege level is 3, the user can configure system parameters. After switching to user privilege level 0, the user can only execute simple commands, like ping and tracert, and only a few display commands. The switching operation is effective for the current login. After the user relogs in, the user privilege restores to the original level.
To avoid problems, HP recommends that administrators log in to the switch by using a lower privilege
level and view switch operating parameters, and when they have to maintain the switch, they can switch to a higher level temporarily
If the administrators need to leave for a while or ask someone else to manage the switch temporarily,
they can switch to a lower privilege level before they leave to restrict the operation by others.
Setting the authentication mode for user privilege level switch
CAUTION:
If no user privilege level is specified when you configure the password for switching the user privilege
level with super password, the user privilege level defaults to 3.
If you specify the simple keyword, the password is saved in the configuration file in plain text, which is
easy to be stolen. If you specify the cipher keyword, the password is saved in the configuration file in cipher text, which is safer.
If the user logs in from the AUX user interface (the console port), the user can switch the privile
e level to a higher level even if the authentication mode is local and no password for user privilege level switch is configured.
A user can switch to a privilege level equal to or lower than the current one unconditionally and is not
required to enter a password (if any).
For security, a user is required to enter the password (if any) to switch to a higher privilege level. The
authentication falls into one of the following four categories:
Authentication mode
local
scheme
Meaning Description
The switch authenticates a user by using the privilege level switch
Local password authentication
Remote AAA authentication through HWTACACS or RADIUS
password entered by the user.
When this mode is applied, you must set the password for privilege level switch with super password.
The switch sends the username and password for privilege level switch to the HWTACACS or RADIUS server for remote authentication.
When this mode is applied, you must perform the following configurations:
Configure HWTACACS or RADIUS scheme and reference the
created scheme in the ISP domain. For more information, see Security Configuration Guide.
Create the corresponding user and configure password on the
HWTACACS or RADIUS server.

By default, log in to a device through the console port, the authentication mode is None (no username or password required), and the user privilege level is 3.
By default, you cannot log in to a device through Telnet. To do so, log in to the device through the console port, and complete the following configuration:
Enable the Telnet function.
Configure the IP address of the VLAN interface, and make sure that
your device and the Telnet client can reach each other (by default, the device does not have an IP address.).
Configure the authentication mode of VTY login users (password

Configure the user privilege level of VTY login users (0 by default).
By default, you cannot log in to a device through SSH. To do so, log in to the device through the console port, and complete the following configuration:
Enable the SSH function and configure SSH attributes.
Configure the IP address of the VLAN interface, and make sure that
your device and the SSH client can reach each other (by default, your device does not have an IP address.).
Configure the authentication mode of VTY login users as scheme
(password by default).
Configure the user privilege level of VTY login users (0 by default).
By default, log in to a device through modems. The default user privilege level of modem login users is 3.
Web login
By default, you cannot log in to a device through web. To do so, log in to the device through the console port, and complete the following configuration:
Configure the IP address of the VLAN interface (by default, your
device does not have an IP address.).
Configure a username and password for web login (not configured
by default).
Configure the user privilege level for web login (not configured by
default).
Configure the Telnet service type for web login (not configured by

Login method Default state
By default, you cannot log in to a device through a network management station (NMS). To do so, log in to the device through the console port, and complete the following configuration:
NMS login
Configure the IP address of the VLAN interface, and make sure the
device and the NMS can reach each other (by default, your device does not have an IP address.).
Configure SNMP basic parameters.
Users and user interfaces
User interface, also called “line," allows you to manage and monitor sessions between the terminal and device when you log in to the device through the console port directly, or through Telnet or SSH.
One user interface corresponds to one user interface view where you can configure a set of parameters, such as whether to authenticate users at login, whether to redirect the requests to another device, and the user privilege level after login. When the user logs in through a user interface, the parameters set for the user interface apply.
The system supports the following CLI configuration methods:
Local configuration via the console port
Local/Remote configuration through Telnet or SSH
The methods correspond to the following user interfaces.
AUX user interface: Used to manage and monitor users that log in via the Console port. The type of the
Console port is EIA/TIA-232 DCE.
VTY (virtual type terminal) user interface: Used to manage and monitor users that log in via VTY. A VTY
port used for Telnet or SSH access.
Only one user can use a user interface at a time. The configuration made in a user interface view applies to any login user. For example, if user A uses the console port to log in, the configuration in the AUX user interface view applies to user A; if user A logs in through VTY 1, the configuration in VTY 1 user interface view applies to user A.
A device can be equipped with one AUX user interface and 16 VTY user interfaces. These user interfaces do not associate with specific users. When a user initiates a connection request, the system automatically assigns an idle user interface with the smallest number to the user based on the login method. During the login, the configuration in the user interface view takes effect. The user interface varies depending on the login method and the login time.
23
Numbering user interfaces
User interfaces can be numbered by using absolute numbering or relative numbering.
Absolute numbering
Absolute numbering identifies a user interface or a group of different types of user interfaces. The specified user interfaces are numbered from number 0 with a step of 1 and in the sequence of AUX, and VTY user interfaces. Use display user-interface command without any parameters to view supported user interfaces and their absolute numbers.
Relative numbering
Relative numbering allows you to specify a user interface or a group of user interfaces of a specific type. The number format is “user interface type + number." The following rules of relative numbering apply:
AUX user interfaces are numbered from 0 in the ascending order, with a step of 1.
VTY user interfaces are numbered from 0 in the ascending order, with a step of 1.
24
g
CLI login
The CLI enables you to interact with a device by typing text commands. At the CLI, instruct your device to perform a given task by typing a text command and then pressing Enter to submit it to your device. Compared with the graphical user interface (GUI), where you can use a mouse to perform configuration, the CLI allows you to enter more information in one command line.
Log in to the device at the CLI through the console port, Telnet, SSH, or modem.
By default, log in to a device through the console port without any authentication, which introduces
security problems.
By default, you cannot log in to a device through Telnet, SSH, so you cannot remotely manage and
maintain the device.
Therefore, you must perform configurations to increase device security and manageability.
Logging in through the console port
Logging in through the console port is the most common login method, and is also the first step to configure other login methods.
By default, log in to a device through its console port only. After logging in to the device through the console port, configure other login methods.

Console login authentication modes
The following authentication modes are available for console port login: none, password, and scheme.
none—Requires no username and password at the next login through the console port. This mode is
insecure.
password—Requires password authentication at the next login through the console port. Keep your
password.
scheme—Requires username and password authentication at the next login through the console port.
Authentication falls into local authentication and remote authentication. To use local authentication, configure a local user and related parameters. To use remote authentication, configure the username and password on the remote authentication server. For more information about authentication modes and parameters, see Security Configuration Guide. Keep your username and password.

On a device that serves as the Telnet client, log in to a Telnet server to perform operations on the server.
On a device that serves as the Telnet server, configure the authentication mode and user privilege level
for Telnet users. By default, you cannot log in to the device through Telnet. Before Telnet to the device, you must log in to the device through the console port, enable Telnet server, and configure the authentication mode, user privilege level, and common settings.
Telnet login authentication modes
Three authentication modes are available for Telnet login: none, password, and scheme.
none—Requires no username and password at the next login through Telnet. This mode is insecure.
password—Requires password authentication at the next login through Telnet. Keep your password. If you
lose your password, log in to the device through the console port to view or modify the password.
scheme—Requires username and password authentication at the next login through Telnet. Authentication
falls into local authentication and remote authentication. To use local authentication, configure a local user and related parameters. To use remote authentication, configure the username and password on the remote authentication server. For more information about authentication modes and parameters, see Security Configuration Guide. Keep your username and password. If you lose your local authentication password, log in to the device through the console port to view or modify the password. If you lose your remote authentication password, contact the administrator.

Web login
Overview
The device provides a built-in web server. It enables you to log in to the web interface of the device from a PC. Web login is disabled by default.
To enable web login, log in to the device via the console port, and perform the following configuration:
Enable HTTP or HTTPS service.
Configure the IP address of the VLAN interface.
Configure a username and password.
The device supports the following web login methods:
HTTP login—Used for transferring web page information across the Internet. It is an application-layer
protocol in the TCP/IP protocol suite. The connection-oriented Transport Control Protocol (TCP) is adopted at the transport layer. The device supports HTTP 1.0.
HTTPS login—Supports the SSL protocol and uses it to encrypt the data exchanged between the HTTPS
client and the server to ensure data security and integrity. Define a certificate attribute-based access control policy to allow legal clients to access the device securely and prohibit illegal clients.
The following table shows the configuration requirements of web login.

SSL related features.
3. Associate the HTTPS
service with an SSL server policy.
4. Enable the HTTPS
service.
system-view
ip https ssl-server-policy

Remarks
Required
By default, PKI and SSL are not configured.
For more information about PKI, see Security
Configuration Guide.
For more information about SSL, see Security
Configuration Guide.
Required
By default, the HTTPS service is not associated with any SSL server policy.
If you disable the HTTPS service, the system
automatically de-associates the HTTPS service from the SSL service policy. Before re-enabling the HTTPS service, associate the HTTPS service with an SSL server policy first.
Any changes to the SSL server policy associated
with the HTTP service that is enabled do not take effect.
Required
Disabled by default.
Enabling the HTTPS service triggers an SSL handshake negotiation process. During the process:
If the local certificate of the device exists, the SSL
negotiation succeeds, and the HTTPS service can be started normally.
If no local certificate exists, a certificate application
process is triggered by the SSL negotiation.
Because the application process takes much time, the SSL negotiation often fails and the HTTPS service cannot be started normally. In that case, you must run ip https enable multiple times to start the HTTPS service.
66
Step Command
5. Associate the HTTPS
service with a certificate attribute-based access control policy.
6. Configure the port
number of the HTTPS service.
7. Associate the HTTPS
service with an ACL.

Remarks
Optional.
By default, the HTTPS service is not associated with any certificate-based attribute access control policy.
Associating the HTTPS service with a
certificate-based attribute access control policy enables the device to control the access rights of clients.
You must configure client-verify enable in the
associated SSL server policy. If not, no clients can log in to the device.
The associated SSL server policy must contain at
least one permit rule. Otherwise, no clients can log in to the device.

NMS login
Overview
A Network Management Station (NMS) runs the SNMP client software. It offers a user-friendly interface to facilitate network management. An agent is a program that resides in the device. It receives and handles requests from the NMS. An NMS is a manager in an SNMP enabled network, whereas agents are managed by the NMS. The NMS and agents exchange information through the SNMP protocol. The device supports multiple NMS programs, such as iMC and CAMS.
By default, you cannot log in to the device through NMS. To enable NMS login, log in to the device via the console port and make the configurations described in the following table.
The following table shows the configuration requirements of NMS login.

Configuring FTP
Overview
FTP is an application layer protocol for sharing files between server and client over a TCP/IP network.
FTP uses TCP ports 20 and 21 for file transfer. Port 20 is used to transmit data, and port 21 to transmit control commands. For more information about FTP basic operations, see RFC 959.
FTP transfers files in the following modes:
ASCII mode—Transfers files as text, like .txt, .bat, and .cfg files.
Binary mode—Transfers files as raw data, like .app, .bin, and .btm files.
Operation
CAUTION:
Make sure that the FTP server and the FTP client can reach each other before establishing the FTP
connection.
When you use IE to log in to the device serving as the FTP server, some FTP functions are not available.
This is because multiple connections are established during the login process but the device supports only one connection at a time.
FTP adopts the client/server model. Your device can function either as the client or the server (as shown in Figure 12).
W
When the device serves as the FTP server, run the FTP client program on the PC to establish a connection

Use display ftp-server to view the FTP server configuration on the device.
Configure the username, password, and authorized directory for an FTP user.
The device does not support anonymous FTP for security reasons. You must set a valid username and password. By default, authenticated users can access the root directory of the device.
Parameters such as the FTP connection timeout time.
Log in to the FTP server only after you enter the correct FTP username and password.
Configuring the FTP client
Only users with the manage level can use ftp to log in to an FTP server, enter FTP client view, and execute directory and file related commands. However, whether the commands can be executed successfully depends on the authorizations of the FTP server.
Establishing an FTP connection
Before access the FTP server, you must first establish a connection from the FTP client to the FTP server. Either use ftp to establish the connection directly or use open command in FTP client view to establish the connection.
When using ftp, specify the source interface (such as a loopback) or source IP address. The primary IP address of the specified source interface or the specified source IP address is used as the source IP address of sent FTP packets. The source address of the transmitted packets is selected following these rules:
If no source address is specified, the FTP client uses the IP address of the interface determined by the
matched route as the source IP address to communicate with an FTP server.
If the source address is specified with the ftp client source or ftp, this source address is used to
communicate with an FTP server.
If you use ftp client source and ftp to specify a source address respectively, the source address specified
with ftp is used to communicate with an FTP server.
The source address specified with ftp client source is valid for all FTP connections and the source address
specified with ftp is valid only for the current FTP connection.

Use either approach.
The ftp command is available in user view, and open is available in FTP client view.
If no primary IP address is configured on the specified source interface, you cannot establish an FTP connection.
If you use ftp client source to configure a source interface and then use it to configure a source IP address, the source IP address overwrites the source interface, and vice versa.
To establish an IPv6 FTP connection:

Configuring the FTP server
Configuring FTP server operating parameters
The FTP server uses one of the following modes to update a file when you upload the file (use put) to the FTP server:
Fast mode—The FTP server starts writing data to the storage medium after a file is transferred to the
memory. This prevents the existing file on the FTP server from being corrupted in the event that anomaly, power failure for example, occurs during a file transfer.
Normal mode—The FTP server writes data to the storage medium while receiving data. This means that
any anomaly, power failure for example, during file transfer might result in file corruption on the FTP server. This mode, however, consumes less memory space than the fast mode.
92
To configure the FTP server:
Step Command Remarks
1. Enter system view. system-view
2. Enable the FTP server
3. Use an ACL to control FTP
clients’ access to the switch.
4. Configure the idle-timeout
timer.
5. Set the file update mode for
the FTP server.
6. Quit to user view.
7. Manually release the FTP
connection established with the specified username.
ftp server enable
ftp server acl acl-number
ftp timeout minutes
ftp update { fast | normal }
quit
free ftp user username
Required.
Disabled by default.
Optional.
By default, no ACL is used to control FTP clients’ access to the switch.
Optional.
30 minutes by default.
Within the idle-timeout time, if there is no information interaction between the FTP server and client, the connection between them is terminated.
Optional.
Normal update is used by default.
Optional.
Available in user view.
Configuring authentication and authorization on the FTP server
To allow an FTP user to access certain directories on the FTP server, you must create an account for the user, authorizing access to the directories and associating the username and password with the account.
The following configuration is used when the FTP server authenticates and authorizes a local FTP user. If the FTP server needs to authenticate a remote FTP user, you must configure authentication, authorization and accounting (AAA) policy instead of the local user. For detailed configuration, see the Security Command Reference.
In local authentication, the switch checks the entered username and password against those configured on the switch. In remote authentication, the switch sends the entered username and password to the remote authentication server, which then checks whether they are consistent with those configured on the switch.
When the switch serves as the FTP server, if the client is to perform the write operations (upload, delete, create, and delete for example) on the device’s file system, the FTP login users must be level 3 users; if the client is to perform other operations, for example, read operation, the switch has no restriction on the user level of the FTP login users.
