display current-configuration diff
archive configuration
Use archive configuration to manually archive the running configuration to the configuration archive directory.
Syntax
archive configuration
Views
User view
Predefined user roles
network-admin
Usage guidelines
Before manually archiving the running configuration, you must use the archive configuration location command to specify a directory and a name prefix for the configuration archives.
Configuration archive facilitates configuration rollback. It provides manual and automatic methods for saving the running configuration. For more information about the archiving mechanism, see the section about configuration rollback in Fundamentals Configuration Guide.
Examples
# Archive the running configuration.
<Sysname> archive configuration
Save the running configuration to an archive file. Continue? [Y/N]: Y
The archive configuration file myarchive_1.cfg is saved.

archive configuration interval
Use archive configuration interval to enable automatic running-configuration archiving and set the archiving interval.
Use undo archive configuration interval to restore the default.
Syntax
archive configuration interval minutes
undo archive configuration interval
Default
The system does not automatically archive the running configuration.

Predefined user roles
network-admin
Parameters
minutes: Specifies the interval (in minutes) for automatically saving the running configuration. The value range is 10 to 525600 (365 days).
Usage guidelines
Before enabling automatic configuration archiving, use the archive configuration location command to specify the configuration archive directory and archive file name prefix.
Configuration archive is a function that facilitates configuration rollback. It provides manual and automatic methods for saving the running configuration.
Automatic configuration archiving enables the system to save the running configuration to the archive directory at the specified interval. For more information about the archiving mechanism, see the section about configuration rollback in Fundamentals Configuration Guide.
Change the archiving interval depending on the amount of available storage space. The shorter the interval, the more free storage space is required.
Examples
# Configure the system to archive the running configuration every 60 minutes.
<Sysname> system-view
[Sysname] archive configuration interval 60
Archive files will be saved every 60 minutes.

archive configuration location
Use archive configuration location to configure the directory and file name prefix for archiving the running configuration.
Use undo archive configuration location to restore the default.
Syntax
archive configuration location directory filename-prefix filename-prefix
undo archive configuration location
Default
No configuration archive directory or configuration archive file name prefix has been set.
Views

Predefined user roles
network-admin
Parameters
directory: Specifies the name of a configuration archive directory, a case-insensitive string of 1 to 63 characters. The directory name must take the format storage-medium-name:/folder-name. This directory must already exist on the master.
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 (-).
Usage guidelines
Before archiving the running configuration, either manually or automatically, you must configure a directory and file name prefix for configuration archives.
In an IRF fabric, the configuration archive function saves the running configuration only on the master device. To ensure that the system can archive the running configuration after a master/subordinate switchover, create the directory on all IRF members.
Configuration archives take the file name format prefix_serial number.cfg, for example, 20080620archive_1.cfg and 20080620archive_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 you change the file directory or file name prefix, or reboot the device, all of the following events occur:
· The old configuration archives are regarded as common configuration files.
· The configuration archive counter is reset.
· The display archive configuration command no longer displays the old configuration archives.
· The serial number for new configuration archives starts at 1.
The undo archive configuration location command removes the configuration archive directory and file name prefix settings. The command also performs the following tasks:
· Disables the configuration archive function (both manual and automatic methods).
· Restores the default settings of the archive configuration interval and archive configuration max commands.
· Clears all configuration archives.
Examples
# Configure 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

archive configuration max
Use archive configuration max to set the maximum number of configuration archives.
Use undo archive configuration max to restore the default.
Syntax
archive configuration max file-number
undo archive configuration max
Default
Up to five configuration archives can be saved.
Views
System view
Predefined user roles
network-admin
Parameters
file-number: Sets the maximum number of configuration archives that can be saved. The value range is 1 to 10. Adjust the setting depending on the amount of storage space available.
Usage guidelines
Before you can set a limit on configuration archives, use the archive configuration location command to specify a configuration archive directory and archive file name prefix.
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 function deletes the oldest n files when a new archive is manually or automatically saved, where n = current archive count – new archive limit + 1.
Suppose 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.
If you execute the undo archive configuration location command, the default archive limit is restored.
Examples
# Set the maximum number of configuration archives to 10.
<Sysname> system-view
[Sysname] archive configuration max 10

backup startup-configuration
Use backup startup-configuration to back up the main next-startup configuration file to a TFTP server.
Syntax
backup startup-configuration to tftp-server [ dest-filename ]
Views
User view
Predefined user roles
network-admin
Parameters
tftp-server: Specifies a TFTP server by its IPv4 address or host name. The host name is a case-insensitive string of 1 to 253 characters. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.).
dest-filename: Specifies the target file name used for saving the file on the server. The file name must use the .cfg extension. If you do not specify a target file name, the source file name is used.
Usage guidelines
This command is not supported in FIPS mode.
Examples
# Back up the main next-startup configuration file to the TFTP server at 2.2.2.2, and set the target file name to 192-168-1-26.cfg.
<Sysname> backup startup-configuration to 2.2.2.2 192-168-1-26.cfg

Parameters
private-key: Encrypts configuration with a private key. All H3C devices running Comware V7 software use the same private key.
public-key: Encrypts configuration with a public key. All H3C devices running Comware V7 software use the same public key.
Usage guidelines
Configuration encryption enables the device to automatically encrypt a configuration file when saving the running configuration to the file.
Only H3C devices running Comware V7 software can decrypt the encrypted configuration file.
Examples
# Enable the public-key method for configuration encryption.
<Sysname> system-view
[Sysname] configuration encrypt public-key
configuration replace file
Use configuration replace file to perform configuration rollback.
Syntax
configuration replace file filename
Views
System view
Predefined user roles
network-admin
Parameters
filename: Specifies the name of the replacement configuration file suffixed with the .cfg extension. Excluding the .cfg extension, the file name is a case-insensitive string of 1 to 191 characters and can include path information. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.). If the file path includes a folder name, the folder must already exist.
Usage guidelines
To replace the running configuration with the configuration in a configuration file without rebooting the device, use the configuration rollback function. This function helps you revert to a previous configuration state or adapt the running configuration to different network environments.
To ensure a successful rollback:
· Make sure the replacement configuration file is created by using the configuration archive function 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.
· Make sure the replacement configuration file is not encrypted.
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

Usage guidelines
Current startup configuration file is the configuration file that has been loaded. Next-startup configuration file is the configuration file used at the next startup.
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 them 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.
Examples
# Display names of the startup configuration files.

Parameters
backup: Deletes the backup next-startup configuration file.
main: Deletes the main next-startup configuration file.
Usage guidelines
|
|
CAUTION: Use this command with caution. This command permanently deletes the next-startup configuration files from all IRF member devices. |
Delete a next-startup configuration file if it does not match the software version or is corrupt.
You can delete the main, the backup, or both.
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 removes the specified file attribute instead of deleting the file.
For example, if the reset saved-configuration backup command is executed, the backup next-startup configuration file setting is set to NULL. However, the file is still used as the main file. To delete the file, you must also execute the reset saved-configuration main command.
If no configuration file attribute is specified, the reset saved-configuration command deletes the main next-startup configuration file.
Examples
# Delete the backup next-startup configuration file.
<Sysname> reset saved-configuration backup
The saved configuration file will be erased. Are you sure? [Y/N]:y

Syntax
restore startup-configuration from tftp-server src-filename
Views
User view
Predefined user roles
network-admin
Parameters
tftp-server: Specifies a TFTP server's IPv4 address or host name. The host name is a case-insensitive string of 1 to 253 characters. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.).
src-filename: Specifies the file name of the configuration file to be downloaded. The name is suffixed with the .cfg extension. Excluding the .cfg extension, the file name is a case-insensitive string of 1 to 191 characters. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.).
Usage guidelines
This command is not supported in FIPS mode.
Before restoring the configuration file for the next startup, make sure the following requirements are met:
· The server is reachable.
· The server is enabled with TFTP service.
· You have read and write permissions to the server.
This command provides an easy method for configuration file restoration by automatically performing all operations required for restoring the main next-startup configuration file.
The command downloads the configuration file to the root directory of each member device's default storage medium and specifies the file as the main next-startup configuration file.
If the USB disk is used and partitioned, the configuration file is saved on the first partition.
This command assumes that all IRF members use the same type of storage medium. If a subordinate device uses a different type of storage medium than the master, the command cannot propagate the configuration file to the subordinate device. For example, the subordinate device uses a USB disk, but the master uses a flash memory. In this situation, you must manually restore the main next-startup configuration file on the subordinate device.
Examples
# Download the configuration file config.cfg from the TFTP server at 2.2.2.2 and specify the file as the main next-startup configuration file.
<Sysname> restore startup-configuration from 2.2.2.2 config.cfg
Restoring the next startup-configuration file from 2.2.2.2. Please wait...finished.

Use save file-url [ all | slot slot-number ] to save the running configuration to a configuration file, without specifying the file as a next-startup configuration file.
Use save [ safely ] [ backup | main ] [ force ] to save the running configuration to a file in the root directory of the default storage medium. This command applies to each member device. It automatically specifies the file as a next-startup configuration file.
Syntax
save file-url [ all | slot slot-number ]
save [ safely ] [ backup | main ] [ force ]
Views
Any view
Predefined user roles
network-admin
Parameters
file-url: Saves the running configuration to the specified file suffixed with the .cfg extension, without specifying the file as a next-startup configuration file. Excluding the .cfg extension, the file name is a case-insensitive string of 1 to 191 characters and can include path information. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.). If you specify the all keyword or a member ID, the file path cannot include a member ID. If the file path includes a folder name, the folder must already exist.
all: Saves the running configuration to all member devices. If you do not specify this keyword or the slot slot-number option, the command saves the running configuration only to the master.
slot slot-number: Saves the running configuration to a subordinate device. The slot-number argument represents the IRF member ID of the device. If you do not specify this option or the all keyword, the command saves the running configuration only to the master.
safely: Saves the configuration file in safe mode. If this keyword is not specified, the device saves the configuration file in fast mode. Safe mode is slower than fast mode, but more secure.
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 without prompting for confirmation. Without this keyword, the system asks 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.
Usage guidelines
If the file specified for the 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 option for the command, the 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.
If you specify the file-url option for the command, the command only saves the running configuration to the specified .cfg file.
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 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 event occurs during this process, the next-startup configuration file is lost.
H3C recommends that you specify the safely keyword for the command.

startup saved-configuration
Use startup saved-configuration to specify a file as a next-startup configuration file for all IRF member devices.
Use undo startup saved-configuration to configure all IRF member devices to start up with the factory defaults at the next startup.
Syntax
startup saved-configuration cfgfile [ backup | main ]
undo startup saved-configuration
Default
No next-startup configuration file is specified.
Views
Predefined user roles
network-admin
Parameters
cfgfile: Specifies the name of a configuration file suffixed with the .cfg extension. Excluding the .cfg extension, the file name is a case-insensitive string of 1 to 191 characters. Valid characters include letters, digits, hyphens (-), underscores (_), and dots (.). This .cfg file must already exist in the root directory of the default storage medium.
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
|
|
CAUTION: In an IRF fabric, use the undo startup saved-configuration command with caution. This command can cause an IRF split after the IRF fabric or an IRF member reboots. |
In an IRF fabric, the startup saved-configuration command applies to all IRF members. To successfully configure the command, verify that the specified file already exists in the root directory of each member's default storage medium.
Make sure all member devices use the same type of storage medium as the default storage medium.
If the USB disk is used to store the next-startup configuration files, do not remove the USB disk during the startup process. If you remove the USB disk on a device, one of the following consequences occurs:
· In a single-chassis IRF fabric, the device starts up with the factory defaults.
· In a multichassis IRF fabric, the device leaves the IRF fabric at startup and runs the factory defaults.
If neither backup nor main is specified, the startup saved-configuration command specifies the main next-startup configuration file.
Even though the main and backup next-startup configuration files can be the same one, specify them as separate files for high availability.
The undo startup saved-configuration command changes the file attribute of the main and backup next-startup configuration files to NULL. 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 to it.
Examples
# Specify the main next-startup configuration file.
<Sysname> startup saved-configuration testcfg.cfg
Please wait ....
... Done.
