Setting Configuration Rollback; Configuration Rollback - HP A7500 Series Configuration Manual

To do...
Save the current configuration to
the specified file, but the
configuration file is not set as the
startup configuration file
Save the current configuration to
the root directory of the storage
media of each MPU of an IRF
fabric and specify the file as the
startup configuration file
NOTE:
The configuration file must have the .cfg extension.
In standalone mode, whether the save [ safely ] [ force ] command or the save
command+Enter takes effect on both the active MPU and standby MPU or only on the active MPU
depends on whether the configuration file auto-save function is enabled. For the configuration file
auto-save function, see
In IRF mode, whether the save [ safely ] [ force ] command or the save
takes effect on all the MPUs or on the active MPU of an IRF fabric depends on whether the configuration
file auto-save function is enabled. For the configuration file auto-save function, see
configuration file
During the execution of the save command, the startup configuration file may be lost if the switch
reboots or the power supply fails. The switch will boot with the factory default configuration, and after
the switch reboots, you will need to re-specify a startup configuration file (see

Setting configuration rollback

Configuration rollback

Configuration rollback allows you to revert to a previous configuration state based on a specified
configuration file. The specified configuration file must be a valid .cfg file generated by using either the
backup function or the save command. If the configuration file is generated by another device, the file
must comply with the format of the configuration file on the current device. HP recommends that you use
the configuration file generated by using the backup function. You can apply configuration rollback in
these situations:
Running configuration error. Rolling back the running configuration to a correct one is needed.
•
The application environment has changed and the device has to run in a configuration state based
•
on a previous configuration file without being rebooted.
Before setting configuration rollback, perform the following steps:
Specify the filename prefix and path for saving the running configuration.
1.
Save the running configuration with the specified filename (filename prefix + serial number) to the
2.
specified path. You can save the running configuration automatically or manually.
When you execute the configuration replace file command, the system compares the running
configuration and the specified replacement configuration file. The configuration replace file command
performs the following actions:
Use the command...
save file-url [ all | chassis
chassis-number slot slot-number ]
save [ safely ] [ force ]
