prefix_serial number.cfg) to the specified path. The filename of a saved configuration file is like
20080620archive_1.cfg, or 20080620archive_2.cfg. The saved configuration files are numbered
automatically, from 1 to 1,000 (with an increment of 1). If the serial number reaches 1,000, it restarts from
1. If you change the path or filename prefix, or reboot the device, the saved file serial number restarts
from 1, and the system recounts the saved configuration files. If you change the path of the saved
configuration files, the files in the original path become common configuration files, and are not
processed as saved configuration files, and are not displayed when you view saved configuration files.
The number of saved configuration files has an upper limit. After the maximum number of files is saved,
the system deletes the oldest files when the next configuration file is saved.
Follow these steps to configure parameters for saving the running configuration:

By default, the path and filename

not configured, and the system

The default number is 5.
NOTE:
•
If the undo archive configuration location command is executed, the running configuration cannot be
saved either manually or automatically, and the configuration is restored to the default by executing the
archive configuration interval and archive configuration max commands, meanwhile, the saved
configuration files are cleared.
• The value of the file-number argument is determined by memory space. You are recommended to set a
comparatively small value for the file-number argument if the available memory space is small.
Enabling automatic saving of the running configuration
You can configure the system to save the running configuration at a specified interval, and use the
display archive configuration command to view the filenames and save time of the saved configuration
files. This enables you to easily roll back the current configuration to a previous configuration state.
Configure an automatic save interval based on the storage media’s performance and the frequency of
configuration modification in the following situations:
• If the configuration of the device does not change frequently, manually save the running
configuration as needed
• If a low-speed storage medium is used, save the running configuration manually, or configure
automatic saving with an interval longer than 1,440 minutes (24 hours).
• If a high-speed storage medium (such as a CF card) is used and the configuration of the device
changes frequently, set a shorter saving interval.
Follow these steps to enable automatic saving of the running configuration:
