2 1 Basic Configuration Commands Basic Configuration Commands clock datetime clock datetime time date User view 3: Manage level time: Time in the format of HH:MM:SS, where HH is hours in the range 0 to 23, MM is minutes in the range 0 to 59, and SS is seconds in the range 0 to 59. The zeros in the argument can be omitted except for indicating 0 hours. date: Date in the format of MM/DD/YYYY or YYYY/MM/DD. MM is the month of the year in the range 1 to 12, DD is the day of the month that varies with months, and YYYY is a year in the range 2000 to Use the clock datetime command to set the current time and date of the device. The current time and date of the device must be set in an environment that requires the acquisition of absolute time. You may choose not to provide seconds when inputting the time parameters. Related commands: clock summer-time one-off, clock summer-time repeating, clock timezone, display clock. # Set the current system time to 14:10:20 08/01/2005. <Sysname> clock datetime 14:10:20 8/1/2005 # Set the current system time to 00:06:00 01/01/2007. <Sysname> clock datetime 0:6 2007/1/1 clock summer-time one-off clock summer-time zone-name one-off start-time start-date end-time end-date add-time undo clock summer-time 1-1

3 System view 3: Manage level zone-name: Name of the daylight saving time, a string of 1 to 32 characters. It is case sensitive. start-time: Start time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. start-date: Start date, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD. end-time: End time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. end-date: End date, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD. add-time: Time added to the standard time of the device, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. Use the clock summer-time one-off command to adopt daylight saving time from the start-time of the start-date to the end-time of the end-date. Daylight saving time adds the add-time to the current time of the device. Use the undo clock summer-time command to cancel the configuration of the daylight saving time. After the configuration takes effect, you can use the display clock command to view it. Besides, the time of the log or debug information is the local time of which the time zone and daylight saving time have been adjusted. Note that: The time range from start-time in start-date to end-time in end-date must be longer than one day and shorter than one year. Otherwise, the argument is considered as invalid and the configuration fails. If the current system time is in the time range specified with this command, the system time automatically adds add-time after the execution of this command. Related commands: clock datetime, clock summer-time repeating, clock timezone, display clock. # For daylight saving time in abc1 between 06:00:00 on 08/01/2006 and 06:00:00 on 09/01/2006, set the system clock ahead one hour.

4 System view 3: Manage level zone-name: Name of the daylight saving time, a string of 1 to 32 characters. start-time: Start time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. start-date: Start date which can be set in two ways: Enter the year, month and date at one time, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD. Enter the year, month and date one by one, separated by spaces. The year ranges from 2000 to 2035; the month can be January, February, March, April, May, June, July, August, September, October, November or December; the start week can be the first, second, third, fourth, fifth or last week of the month; the start date is Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday. end-time: End time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. end-date: End date which can be set in two ways: Enter the year, month and date at one time, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD. Enter the year, month and date one by one, separated by spaces. The year ranges from 2000 to 2035; the month can be January, February, March, April, May, June, July, August, September, October, November or December; the end week can be the first, second, third, fourth, fifth or last week of the month; the end date is Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday. add-time: Time added to the current standard time of the device, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours. Use the clock summer-time repeating command to adopt summer-time repeatedly. Use the undo clock summer-time command to cancel the configuration of the daylight saving time. For example, when start-date and start-time are set to 2007/6/6 and 00:00:00, end-date and end-time to 2007/10/01 and 00:00:00, and add-time to 01:00:00, it specifies to adopt daylight saving time from 00:00:00 of June 6 until 00:00:00 of October 1 each year from 2007 (2007 inclusive). The daylight saving time adds one hour to the current device time. After the configuration takes effect, use the display clock command to view the result. The information such as log file and debug adopts the local time modified by time-zone and daylight saving time. Note that: The time range from start-time in start-date to end-time in end-date must be longer than one day and shorter than one year. Otherwise, the argument is considered as invalid and the configuration fails. 1-3

5 If the current system time is in the time range specified with this command, the system time automatically adds add-time after the execution of this command. Related commands: clock datetime, clock summer-time one-off, clock timezone, display clock. # For the daylight saving time in abc2 between 06:00:00 on 08/01/2007 and 06:00:00 on 09/01/2007 and from 06:00:00 08/01 to 06:00:00 on 09/01 each year after 2007, set the system clock ahead one hour. [Sysname] clock summer-time abc2 repeating 06:00:00 08/01/ :00:00 09/01/ :00:00 clock timezone clock timezone zone-name { add minus } zone-offset undo clock timezone System view 3: Manage level zone-name: Time zone name, a string of 1 to 32 characters. It is case sensitive. add: Positive to universal time coordinated (UTC) time. minus: Negative to UTC time. zone-offset: Offset to the UTC time in the format of HH/MM/SS (hours/minutes/seconds), where HH is hours in the range 0 to 23, MM is minutes in the range 0 to 59, and SS is seconds in the range 0 to 59. The zeros in the argument can be omitted except for indicating 0 hours. Use the clock timezone command to set the local time zone. Use the undo clock timezone command to restore the local time zone to the default UTC time zone. By default, the local time zone is UTC zone. After the configuration takes effect, use the display clock command to view the result. The information such as log file and debug adopts the local time modified by time-zone and daylight saving time. Related commands: clock datetime, clock summer-time one-off, clock summer-time repeating, display clock. # Set the name of the local time zone to Z5, five hours ahead of UTC time. [Sysname] clock timezone z5 add 5 1-4

6 command-privilege level command-privilege level level view view command undo command-privilege view view command System view 3: Manage level level level: Command level, in the range 0 to 3. view view: Specifies a view. The value shell of the argument view represents user view. The specified view must be the view to which the command provided by the command argument belongs; for the corresponding view, refer to the "" section of the specified command. command: Command to be set in the specified view. Use the command-privilege command to assign a level for the specified command in the specified view. Use the undo command-privilege view command to restore the default. By default, each command in a view has its specified level. For the details, refer to section Configuring User Privilege Levels and Command Levels in the operation manual. Command level falls into four levels: visit, monitor, system, and manage, which are identified by 0 through 3. The administrator can assign a privilege level for a user according to his need. When the user logs on a device, the commands available depend on the user s privilege. For example, if a user s privilege is 3 and the command privilege of VTY 0 user interface is 1, and the user logs on the system from VTY 0, he can use all the commands with privilege smaller than three (inclusive). Note that: You are recommended to use the default command level or modify the command level under the guidance of professional staff; otherwise, the change of command level may bring inconvenience to your maintenance and operation, or even potential security problem. When you configure the command-privilege command, the value of the command argument must be a complete form of the specified command, that is, you must enter all needed keywords and arguments of the command. The argument should be in the value range. For example, the default level of the tftp server-address { get put sget } source-filename [ destination-filename ] [ source { interface interface-type interface-number ip source-ip-address } ] command is 3; after the command-privilege level 0 view shell tftp put a.cfg command is executed, when users with the user privilege level of 0 log in to the device, they can execute the tftp server-address put source-filename command (such as the tftp put syslog.txt command); users with the user privilege level of 0 cannot execute the command with the get, sget or source keyword, and cannot specify the destination-filename argument. 1-5

7 When you configure the undo command-privilege view command, the value of the command argument can be an abbreviated form of the specified command, that is, you only need to enter the keywords at the beginning of the command. For example, after the undo command-privilege view system ftp command is executed, all commands starting with the keyword ftp (such as ftp server acl, ftp server enable, and ftp timeout) will be restored to the default level; if you have modified the command level of commands ftp server enable and ftp timeout, and you want to restore only the ftp server enable command to its default level, you should use the undo command-privilege view system ftp server command. If you modify the command level of a command in a specified view from the default command level to a lower level, remember to modify the command levels of the quit command and the corresponding command that is used to enter this view. For example, the default command level of commands interface and system-view is 2 (system level); if you want to make the interface command available to the users with the user privilege level of 1, you need to execute the following three commands: command-privilege level 1 view shell system-view, command-privilege level 1 view system interface ethernet 2/0/1, and command-privilege level 1 view system quit, so that the login users with the user privilege level of 1 can enter system view, execute the interface ethernet command, and then return to user view. # Set the command level of the interface command to 0 in system view. [Sysname] command-privilege level 0 view system interface display clipboard display clipboard Any view 1: Monitor level None Use the display clipboard command to view the contents of the clipboard. To copy the specified content to the clipboard: Move the cursor to the starting position of the content and press the <Esc+Shift+,> combination (, is an English comma). Move the cursor to the ending position of the content and press the <Esc+Shift+.> combination (. is an English dot) to copy the specified content to the clipboard. # the content of the clipboard. 1-6

8 <Sysname> display clipboard CLIPBOARD telnet server enable display clock display clock Any view 1: Monitor level None Use the display clock command to view the current system time and date. The current system time and date are decided by the clock datetime, clock summer-time one-off (or clock summer-time repeating), clock timezone. Refer to Configuring the system clock in the operation manual for the detailed rules. Related commands: clock datetime, clock summer-time one-off, clock summer-time repeating, clock timezone. # Display the current time and date. <Sysname> display clock 09:41:23 UTC Thu 12/15/2005 display current-configuration display current-configuration [ [ configuration [ configuration ] interface [ interface-type ] [ interface-number ] ] [ by-linenum ] [ { begin exclude include } regular-expression ] ] Any view 2: System level configuration [ configuration ]: Specifies to display non-interface configuration. If no parameter is used, all the non-interface configuration is displayed; if parameters are used, display the specified information. For example: 1-7

For the detailed description of the regular expression, refer to the CLI Display part of Basic System Configuration in the System Volume. begin: Displays the line that matches the regular expression and all the subsequent lines. exclude: Displays the lines that do not match the regular expression. include: Displays only the lines that match the regular expression. regular-expression: Regular expression, a string of 1 to 256 characters. Note that this argument is case-sensitive and can have spaces included. Use the display current-configuration command to display the current validated configuration of a device. You can use the display current-configuration command to view the currently validated configuration. A parameter is not displayed if it has the default configuration. If the validated parameter is changed, although you have configured it, the validated parameter is displayed. For example, ip address has been configured on a Loopback interface. In this case, if you execute the display current-configuration command, ip address is displayed, meaning the validated subnet mask is 32 bits. Related commands: save, reset saved-configuration, display saved-configuration. # Display the configuration of VLAN-interface 1 of the current device (the output information depends on the device model and the current configuration). <Sysname> display current-configuration interface vlan-interface 1 # interface Vlan-interface1 ip address igmp group-policy 2000 igmp static-group source multicast boundary multicast boundary ntp-service multicast-server ntp-service multicast-server ntp-service multicast-server # return 1-8

20 User view 1: Monitor level None Use the screen-length disable command to disable the multiple-screen output function of the current user. Use the undo screen-length disable command to enable the multiple-screen output function of the current user. By default, a login user uses the settings of the screen-length command. The default settings of the screen-length command are: multiple-screen output is enabled and 24 lines are displayed on the next screen. (For the details of the screen-length command, refer to User Interface Commands in the System Volume.) Note that this command is applicable to the current user only and when a user re-logs in, the settings restore to the system default. # Disable multiple-screen output of the current user. <Sysname> screen-length disable super super [ level ] User view 0: Visit level level: User level, in the range 0 to 3, and defaults to 3. Use the super command to switch from the current user privilege level to a specified user privilege level. If you do not provide the level argument, the current user privilege level will be switched to 3. Login users are classified into four levels that correspond to the four command levels. After users at different levels log in, they can only use commands at their own, or lower, levels. 1-19

21 Users can switch to a lower user privilege level unconditionally. However, no password is needed only for AUX login user level switching; to switch to a higher user privilege level, and log in from VTY user interfaces, users need to enter the password needed for the security s sake. If the entered password is incorrect or no password is configured, the switching fails. Therefore, before switching a user to a higher user privilege level, you should configure the password needed. Related commands: super password. # Set the user privilege level to 2 (The current user privilege level is 3.). <Sysname> super 2 User privilege level is 2, and only those commands can be used whose level is equal or less than this. Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE # Switch the user privilege level back to 3 (Suppose password 123 has been set; otherwise, the user privilege level cannot be switched to 3.). <Sysname> super 3 Password: User privilege level is 3, and only those commands can be used whose level is equal or less than this. Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE super password super password [ level user-level ] { simple cipher } password undo super password [ level user-level ] System view 2: System level level user-level: User privilege level in the range 1 to 3, with the default as 3. simple: Plain text password. cipher: Cipher text password. password: Password, a string of characters. It is case-sensitive. For simple password, it is a string of 1 to 16 characters. For cipher password, it is a string of 1 to 16 characters in plain text or 24 characters in cipher text. For example, the simple text corresponds to the cipher text (TT8F]Y\5SQ=^Q`MAF4<1!!. 1-20

22 Use the super password command to set the password needed to switch from a lower user privilege level to a higher one. Use the undo super password command to restore the default. By default, no password is set to switch from a lower user privilege level to a higher one. Note that: If simple is specified, the configuration file saves a simple password. If cipher is specified, the configuration file saves a cipher password. The user must always enter a simple password, no matter simple or cipher is specified. Cipher passwords are recommended, as simple ones are easily getting cracked. # Set the password to abc in simple form for switching user-level to 3. [Sysname] super password level 3 simple abc Display the password for switching user-level.
