IMPORTANT:
• Do not move or copy a private-key-encrypted configuration file between MPUs. These actions can cause
a decryption failure because the MPUs use different private keys.
• When the configuration encryption function is enabled, you cannot convert the operating mode
between standalone and IRF. Before converting the operating mode, you must first disable the
configuration encryption function.
To enable configuration encryption:

Saving the running configuration
When saving the running configuration to a configuration file, you can specify the file as a next-startup
configuration file.
If you are specifying the file as a next-startup configuration file, use one of the following methods to save
the configuration:
• Fast mode—Use the save command without the safely keyword. In this mode, the device directly
overwrites the target next-startup configuration file. If a reboot or power failure occurs during this
process, the next-startup configuration file is lost. You must specify a new startup configuration file
after the device reboots (see "Specifying a next-startup configuration file")
.
• Safe mode—Use the save command with the safely keyword. Safe mode is slower than fast mode,
but more secure. 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
or power failure occurs during the save operation, the next-startup configuration file is still retained.
Use the safe mode if the power source is not reliable or you are remotely configuring the device.
To save the running configuration, perform either of the following tasks in any view:
