network-admin

Usage guidelines

Operating mechanism

This command saves the running configuration to the specified configuration archive directory with file names generated from the specified name prefix.

Restrictions and guidelines

Before executing this command, you must use one of the following methods to specify a directory and a name prefix for the configuration archives:

·     For local archiving, use the archive configuration location command to specify a local configuration archive directory and a name prefix.

·     For remote archiving, use the archive configuration server command to specify a configuration archive directory and a name prefix on a remote SCP server.

If you execute the archive configuration location command to specify a local configuration archive directory, manual configuration archiving saves the running configuration only on the master device.

Examples

# Archive the running configuration.

<Sysname> archive configuration

Save the running configuration to an archive file. Continue? [Y/N]: Y

The running configuration was saved to myarchive_1.cfg.

Parameters

directory: Specifies the archive directory, a string of 1 to 63 characters. The value for this argument must take the format of storage-medium-name:/folder-name. If you do not specify this argument, the system will automatically complete the archive directory and its length will be calculated. If the directory length exceeds 63 characters, the command execution will fail. The directory must already exist on the master device and the option cannot contain any member ID.

filename-prefix: Specifies a file name prefix for configuration archives, a case-insensitive string of 1 to 30 characters. Valid characters are letters, digits, underscores (_), and hyphens (-).

interval interval: Enables automatic running-configuration archiving and sets the archiving interval. The value range for the interval argument is 10 to 525600, in minutes. By default, automatic running-configuration archiving is disabled.

max file-number: Specifies the maximum number of configuration archives that can be saved on the device in the range of 1 to 10. Adjust the setting depending on the amount of storage space available. For devices with limited storage space, set a smaller value for the file-number argument. The default value for the file-number argument is 5.

Usage guidelines

Operating mechanism

You can use the following methods to archive the running configuration to a local directory:

·     Manual configuration archiving: After you execute this command to specify the parameters for archiving the running configuration to a local directory, execute the archive configuration command for manual configuration archiving.

·     Automatic configuration archiving: Specify the interval keyword to enable automatic running-configuration archiving. After you execute this command, the system saves the running configuration to the local archive directory at the interval specified by the interval argument. After the system finishes an automatic archive, it resets the archiving interval timer.

The local configuration archives on the device are named in the format of prefix_serial number.cfg, for example, archive_1.cfg and archive_2.cfg. The serial number is automatically assigned from 1 to 1000, increasing by 1. After the serial number reaches 1000, it restarts from 1.

After the maximum number of configuration archives is reached, the system deletes the oldest archive for the new archive. Changing the limit setting to a lower value does not cause immediate deletion of excess archives. Instead, the configuration archive feature deletes the oldest n files when a new archive is manually or automatically saved, where n = current archive count – new archive limit + 1. For example, seven configuration archives have been saved before the archive limit is set to four. When saving a new configuration archive, the system first deletes the oldest four (7 – 4 + 1) archives.

Restrictions and guidelines

The system saves the running configuration only on the master device.

After you execute the undo archive configuration location command, the output from the display archive configuration command will be cleared.

The archive configuration server and archive configuration location commands are mutually exclusive. To execute the archive configuration server command, you must restore the default for the archive configuration location command, and vice versa.

Examples

# Set the configuration archive directory as flash:/archive and the archive file name prefix as my_archive.

<Sysname> mkdir flash:/archive

Creating directory flash:/archive... Done.

<Sysname> system-view

[Sysname] archive configuration location flash:/archive filename-prefix my_archive

Usage guidelines

Operating mechanism

Configuration encryption enables the device to automatically encrypt a configuration file by using the master key when saving the running configuration to the file. For more information about the master key, see public key management in Security Configuration Guide.

Restrictions and guidelines

After a configuration file is encrypted by using this feature on the device, only devices that use the same master key as the device can decrypt the encrypted configuration file.

Examples

# Enable configuration encryption.

<Sysname> system-view

[Sysname] configuration encrypt

configuration exclusive by-user-name

Use configuration exclusive by-user-name to assign a user exclusive write access to the configuration.

Use undo configuration exclusive by-user-name to restore the default.

Syntax

configuration exclusive by-user-name user-name

undo configuration exclusive by-user-name user-name

Default

The configuration is not locked. No users have exclusive write access to the configuration.

Views

System view

Predefined user roles

network-admin

Parameters

user-name: Specifies a username, a case-sensitive string of 1 to 80 characters.

Usage guidelines

Application scenarios

In a multiuser environment, configuration conflicts or service exceptions might occur if multiple users are configuring the device.

To make sure only one user can change the running configuration, assign that user exclusive write access to the configuration. This setting locks the configuration. Then, all other users will have only read access to the configuration until the configuration is unlocked.

This command is available only for users that log in to the device through scheme authentication. Scheme authentication requires a username and password.

Restrictions and guidelines

Only one user can lock the configuration at a time.

To unlock the configuration, use the undo configuration exclusive by-user-name user-name command. The user-name argument must be the username that locked the configuration. To obtain this username, use the display configuration exclusive by-user-name command.

The configuration exclusive by-user-name command no longer takes effect after the device reboots. To use this command, you must reconfigure it.

Examples

# Assign user aaa exclusive write access to the configuration.

<Sysname> system-view

[Sysname] configuration exclusive by-user-name aaa

Predefined user roles

network-admin

Parameters

filename: Specifies the path of the replacement configuration file, a string of up to 255 characters. The file must be a .cfg file. The file and file path must be valid and on the local system.

Usage guidelines

Prerequisites

Prepare the replacement configuration file. Make sure the replacement configuration file is created by using the configuration archive feature or the save command on the device. If the configuration file is not created on the device, make sure the command lines in the configuration file are fully compatible with the device.

Operating mechanism

The configuration replace file command helps you revert to a previous configuration state or adapt the running configuration to different network environments without rebooting the device. Settings not in the replacement configuration file will be lost.

Restrictions and guidelines

This operation might cause service interruption. When you perform configuration rollback, make sure you fully understand its impact on your network.

If the replacement configuration file is encrypted, make sure the device can decrypt it.

Examples

# Replace the running configuration with the configuration in the my_archive_1.cfg configuration file.

<Sysname> system-view

[Sysname] configuration replace file my_archive_1.cfg

Current configuration will be lost, save current configuration? [Y/N]:n

Parameters

ftp: Specifies a remote FTP server.

tftp: Specifies a remote TFTP server.

ipv4-address: Specifies the IPv4 address of the remote server.

ipv6 ipv6-address: Specifies the IPv6 address of the remote server.

port port-number: Specifies the TCP port number of the remote server, in the range of 1 to 65535. By default, the FTP port number is 21 and the TFTP port number is 69.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If the remote server is on the public network, do not specify this option.

directory directory: Specifies the remote rollback directory. The directory argument is a case-insensitive string. If you do not specify this option, the rollback directory is the root directory of the remote server.

file filename: Specifies the default replacement configuration file for running-configuration remote rollback. The filename argument is a case-insensitive string. The file must be a .cfg file.

Usage guidelines

If you use a remote FTP server, make sure the device is consistent with that FTP server in FTP settings. If a login username and password is configured on the FTP server, you must use the configuration replace server user and configuration replace server password commands to specify that login username and password on the device.

Examples

# Replace the running configuration with the configuration in the archive/ directory of the FTP server at 192.168.1.1.

<Sysname> system-view

Parameters

filename: Specifies a replacement configuration file by its name, a string of up to 255 characters. The file must be a .cfg file. If you do not specify a replacement configuration file, this command uses the default replacement configuration file specified by using the configuration replace server command for a rollback.

at time: Specifies the time at which the system downloads the replacement configuration file and performs configuration rollback. The time argument is in the format of HH:MM. HH represents the hours, in the range of 0 to 23. MM represents the minutes, in the range of 0 to 59.

date: Specifies the date on which the system downloads the replacement configuration file and performs configuration rollback. This argument is in the format of MM/DD/YYYY or YYYY/MM/DD. YYYY represents the year, in the range of 2000 to 2035. MM represents the month, in the range of 1 to 12. DD represents the day, in the range of 1 to N. The value for N depends on the month.

Usage guidelines

Operating mechanism

This command enables the device to perform the following operations:

1.     Downloads the replacement configuration file from the remote rollback server.

2.     Saves the downloaded file as a temporary file.

3.     Replaces the running configuration with the configuration in the temporary file.

4.     Deletes the temporary file after the configuration rollback finishes.

To perform an immediate configuration rollback, do not specify a rollback time or date. An immediate configuration rollback cannot be canceled.

To schedule a configuration rollback, specify a rollback time and optionally a date. A configuration rollback schedule can be canceled before the specified rollback time.

Restrictions and guidelines

The configuration rollback operation might cause service interruption. When you perform configuration rollback, make sure you fully understand its impact on your network.

When you schedule a rollback, follow these restrictions and guidelines:

·     If you specify a rollback date with the rollback time, the specified date must be the same or later than the current system date. If the specified date is the same as the current system date, the specified time must be later than the current system time. After you create the rollback schedule, be careful with changing the system clock backward. The rollback schedule will be canceled automatically if it expires before it could be executed because the system date or time is changed backward.

·     If you do not specify a rollback date with the rollback time, the device compares the specified rollback time with the current system time.

¡     If the specified rollback time is later than the current system time, the device performs a rollback at the specified time on the current day.

¡     If the specified rollback time is earlier than the current system time, the device performs a rollback at the specified time on the next day.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Roll back the running configuration immediately with the specified replacement configuration file on the remote server for configuration rollback.

<Sysname> system-view

[Sysname] configuration replace server file my_archive_2017-05-09.cfg

The running configuration will be lost. Do you want to save the running configuration? [Y/N]: N

Parameters

configfile file-name-s: Specifies the source configuration file for comparison.

configfile file-name-d: Specifies the target configuration file for comparison.

current-configuration: Specifies the running configuration. In the display diff current-configuration command, this keyword specifies the source configuration for comparison. In the display diff configfile file-name-s and display diff startup-configuration commands, this keyword specifies the target configuration.

startup-configuration: Specifies the next-startup configuration. In the display diff startup-configuration command, this keyword specifies the source configuration for comparison. In the display diff configfile file-name-s and display diff current-configuration commands, this keyword specifies the target configuration.

Usage guidelines

If you specify the startup-configuration keyword, the system searches for the next-startup configuration in the following order:

7.     The .cfg main next-startup configuration file.

8.     The .cfg backup next-startup configuration file if the .cfg main next-startup configuration file is unavailable.

If both configuration files are unavailable, the system displays a message indicating that no next-startup configuration files exist.

Restrictions and guidelines

All IRF members use the same current startup configuration file as the master.

After a master/subordinate switchover, it is normal that the current startup configuration files on all IRF members are displayed as NULL. This is because the new master continues to run with the running configuration rather than rebooting with a startup configuration file.

Parameters

backup: Specifies the backup next-startup configuration file.

main: Specifies the main next-startup configuration file.

Usage guidelines

Application scenarios

If a next-startup configuration file is no longer in use, you can delete it.

Parameter description

If you do not specify a configuration file attribute, the reset saved-configuration command deletes the main next-startup configuration file.

Restrictions and guidelines

By default, this command permanently deletes the specified next-startup configuration file from all IRF member devices. To delete the configuration file only from the master device, disable automatic system-wide next-startup configuration file operations. For more information about disabling these operations, see configuration file management in Fundamentals Configuration Guide.

To delete a file that is set as both main and backup next-startup configuration files, you must execute both the reset saved-configuration backup command and the reset saved-configuration main command. Using only one of the commands sets the target file attribute to NULL instead of deleting the file.

Examples

# Delete the main next-startup configuration file.

Parameters

file-url: Specifies a file path, a string of up to 255 characters, which must end with .cfg. If you specify the all keyword or the slot slot-number option, the file path cannot include a member ID. If the file path includes a folder name, the folder must already exist on the specified IRF member devices.

all: Saves the running configuration to all member devices. If you do not specify a subordinate device or the all keyword, this command saves the running configuration only to the master device.

slot slot-number: Specifies a subordinate device by its member ID. If you do not specify a subordinate device or the all keyword, this command saves the running configuration only to the master device.

safely: Saves the configuration file in safe mode. If you do not specify this keyword, the device saves the configuration file in fast mode.

backup: Saves the running configuration to a configuration file, and specifies the file as the backup next-startup configuration file. If you do not specify this keyword or the main keyword, the command specifies the saved file as the main next-startup configuration file.

main: Saves the running configuration to a configuration file, and specifies the file as the main next-startup configuration file. If you do not specify this keyword or the backup keyword, the command specifies the saved file as the main next-startup configuration file.

force: Saves the running configuration to the existing next-startup configuration file without prompting for confirmation. If you do not specify this keyword, the system prompts you to confirm the operation. If you do not confirm the operation within 30 seconds, the system automatically aborts the operation. If you enter Y within the time limit, you can continue the save process and change the target file name during the process.

changed: Overwrites the target configuration file with the running configuration if an inconsistency is detected between the settings in the configuration file and the running configuration. The save command does not take effect if no inconsistency is detected. If you do not specify this keyword, the save command always overwrites the target configuration file with the running configuration.

Usage guidelines

Operating mechanism

This command saves the running configuration to an .mdb binary file as well as a .cfg text file. The two files use the same file name. An .mdb file takes less time to load than a .cfg file.

Restrictions and guidelines

Use the save command with caution. This command will overwrite the settings in the target configuration file. When you execute this command, carefully read the messages displayed by the system and make sure you fully understand the impact of this command on services.

If the file specified for this command does not exist, the system creates the file before saving the configuration. If the file already exists, the system prompts you to confirm whether to overwrite the file. If you choose to not overwrite the file, the system cancels the save operation.

If you do not specify the file-url argument, the device saves the running configuration to the root directory of the storage media and specifies the configuration file as the next-startup configuration file. If you specify the file-url argument, the device only saves the running configuration file to the specified path.

When you use the save [ safely ] [ backup | main ] [ force ] [ changed ] command, follow these guidelines:

·     In safe mode, the system saves configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot, power failure, or out of memory or storage space event occurs during the save operation, the next-startup configuration file is retained.

·     In fast mode, the device directly overwrites the target next-startup configuration file. If a reboot, power failure, or out of memory or storage space event occurs during this process, all settings in the next-startup configuration file are lost.

Safe mode is slower than fast mode, but more secure. As a best practice, specify the safely keyword for reliable configuration saving.

By default, the save [ safely ] [ backup | main ] [ force ] command saves the configuration to all IRF member devices. To save the configuration only to the master device, disable automatic system-wide next-startup configuration file operations. For more information about disabling these operations, see configuration file management in Fundamentals Configuration Guide.

If containers have been created on the device, follow these guidelines when you use the save command to save the running configuration:

·     If you do not specify the force keyword, the system prompts you to confirm whether to save the settings of the containers.

¡     If you enter Y at the prompt, the system saves the settings of the containers for the settings to survive a reboot. Saving the container settings will take some time.

¡     If you enter N at the prompt or do not confirm the prompt in 30 seconds, the system continues the saving process without saving the container settings.

·     If you specify the force keyword, the system saves the container settings without any confirmation required.

Parameters

interval: Sets the automatic saving interval, in minutes. The value range is 10 to 525600.

sec seconds-interval: Sets the automatic saving interval, in seconds. The value range is 1 to 31536000.

Usage guidelines

Operating mechanism

This feature enables the device to automatically save the running configuration to both the .cfg and .mdb main next-startup configuration files at intervals. At each interval, the device performs an automatic saving operation only if the running configuration contains different settings than the main next-startup configuration files.

If no main next-startup configuration files exist, this feature automatically creates configuration files startup.cfg and startup.mdb to save the running configuration and specifies the files as the main next-startup configuration files.

This feature saves the running configuration to all member devices.

Default

Next-startup configuration file operations are automatically synchronized across the entire system.

Views

System view

Predefined user roles

network-admin

Usage guidelines

By default, automatic system-wide next-startup configuration file operations are enabled. The system performs the following operations on all IRF subordinate devices in addition to the master device:

·     Saves the running configuration to the next-startup configuration file on each member device when you execute the save save [ safely ] [ backup | main ] [ force ] [changed ] command.

·     Deletes the next-startup configuration file on each member device when you execute the reset saved-configuration command.

If you disable automatic system-wide next-startup configuration file operations, the system saves the running configuration or deletes the next-startup configuration file only on the master device.

Automatic system-wide operations ensure start-up configuration file consistency between the master and subordinate devices. However, a system-wide operation takes more time than an operation performed only on the master device. In addition, the amount of time required to complete a system-wide configuration operation increases as the amount of configuration data grows.

If you are disabling automatic system-wide operations for faster configuration saving, be aware that the next-startup configuration files will be inconsistent between the master device and the subordinate devices.

Examples

# Enable automatic system-wide next-startup configuration file operations.

Views

User view

Predefined user roles

network-admin

Parameters

cfgfile: Specifies the path of a configuration file, a string of up to 255 characters. The file must be a .cfg file. The file path can include only the file name, or the storage medium information and file name. If the file is not on the default storage medium, you must specify the file name with storage medium information.

backup: Specifies the configuration file as the backup next-startup configuration file.

main: Specifies the configuration file as the main next-startup configuration file. This is the primary configuration file that the device attempts to load at startup. If the loading attempt fails, the device tries the backup next-startup configuration file.

Usage guidelines

Prerequisites

Make sure the same file is specified as the next-startup configuration file on all member devices in an IRF fabric. Therefore, before executing this command, make sure the specified configuration file is saved in the root directory on the same type of storage medium for all member devices. If you fail to do so, the configuration will fail.

Recommended configuration

As a best practice, specify different files as the main and backup next-startup configuration files.

Parameter description

If you do not specify the backup or main keyword, the startup saved-configuration command specifies the main next-startup configuration file.

Restrictions and guidelines

The undo startup saved-configuration command changes the file attribute of the main and backup next-startup configuration files to NULL. However, the command does not delete the two configuration files.

You can also specify a configuration file as a next startup file when you use the save command to save the running configuration.

In an IRF fabric, the undo startup saved-configuration command can cause an IRF split after the IRF fabric or an IRF member reboots.

Examples

# Specify the main next-startup configuration file.

<Sysname> startup saved-configuration testcfg.cfg

Please wait ....... Done.
