z
Applies the commands from the replacement configuration file that have different configurations in
the current running configuration.
The current running configuration is only saved to the AMB, and only the configuration on the AMB can
be rolled back. However, the related configuration will be synchronized to the SMB to ensure the
rollback of the configuration after an active/standby switchover. (On the SR6604/6608/6616 router)

Configuring Parameters for Saving the Current Running Configuration
Before the current running configuration is saved manually or automatically, the file path and filename
prefix must be configured. After that, the system saves the current running configuration with the
specified filename (filename 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 current running configuration:
