Default Level

3: Manage level

Parameters

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.

Description

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.

By default, daylight saving time is configured on the device, and the universal time coordinated (UTC) time zone is applied.

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:

l          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.

l          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.

Examples

# 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.

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.

Description

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.

By default, daylight saving time is configured on the device, and the universal time coordinated (UTC) time zone is applied.

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:

l          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.

l          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.

Examples

# 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.

command-privilege

Syntax

command-privilege level level view view command

undo command-privilege view view command

View

System view

Default Level

3: Manage level

Parameters

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 "View" section of the specified command.

command: Command to be set in the specified view.

Description

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 the related part of Basic System Configuration in this 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:

l          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.

l          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 1.1.1.1 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 192.168.1.26 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.

l          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.

l          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 1/1, 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.

Examples

# Set the command level of the system-view command in user view to 3. (By default, users with the user privilege level of 2 or 3 can use the system-view command after login; after the following configuration, only users with the user privilege level of 3 can use this command to enter system view and configure the device. Therefore, the device security is improved.)

super

Syntax

super [ level ]

View

User view

Default Level

0: Visit level

Parameters

level: User level, in the range 0 to 3, and defaults to 3.

Description

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.

Note that:

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.

Examples

# 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

Syntax

super password [ level user-level ] { simple | cipher } password

undo super password [ level user-level ]

View

System view

Default Level

2: System level

Parameters

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.

l          For simple password, it is a string of 1 to 16 characters.

l          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 “1234567” corresponds to the cipher text “(TT8F]Y\5SQ=^Q`MAF4<1!!”.

Description

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:

l          If simple is specified, the configuration file saves a simple password.

l          If cipher is specified, the configuration file saves a cipher password.

l          The user must always enter a simple password, no matter simple or cipher is specified.

l          Cipher passwords are recommended, as simple ones are easily getting cracked.

Examples

# Set the password to abc in simple form for switching user-level to 3.

<Sysname> system-view

[Sysname] super password level 3 simple abc

Display the password for switching user-level.

[Sysname] display current-configuration

#

 super password level 3 simple abc

# Set the password to abc in cipher form for switching user-level to 3.

<Sysname> system-view

[Sysname] super password level 3 cipher abc

Display the password for switching user-level.

[Sysname] display current-configuration

#

 super password level 3 cipher =`*Y=F>*.%-a_SW8\MYM2A!!
