Configuring Configuration Rollback; Configuration Task List - HP 5920 series Fundamentals Configuration Manual

Task
Save the running configuration to
a configuration file without
specifying the file as a
next-startup configuration file.
Save the running configuration to
a configuration file and specify
the file as a next-startup
configuration file.

Configuring configuration rollback

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.
The configuration rollback function compares the running configuration against the specified
replacement configuration file and handles configuration differences as follows:
If a command in the running configuration is not in the replacement file, the rollback function
•
executes the undo form of the command.
• If a command in the replacement file is not in the running configuration, the rollback function adds
the command to the running configuration.
If a command has different settings in the running configuration and the configuration file, the
•
rollback function replaces the running command setting with the setting in the configuration file.
To facilitate configuration rollback, the configuration archive function was developed. This function
enables the system to save the running configuration automatically at regular intervals.

Remarks
N/A
For reliable configuration saving, HP
recommends that you specify the safely
keyword.
If you execute the save [ safely ]
command without specifying any other
keyword, the command saves the
configuration to the main startup
configuration file.
If the force keyword is specified, the
command saves the configuration to the
existing next-startup configuration file.
If the force keyword is not specified, the
command allows you to specify a new
next-startup configuration file.
