Using Automatic Configuration Backup After A Software Upgrade; Specifying A Configuration File For The Next Startup; Backing Up The Next-Startup Configuration File To A Tftp Server - HP 830 Series Configuration Manual

Using automatic configuration backup after a software
upgrade
After a software upgrade, the system by default starts up with the next-startup configuration file created
on the old software version, but the system does not load settings that are incompatible with the new
software version to the current configuration.
In case a future downgrade is needed, the system automatically checks for configuration incompatibility
and backs up the old next-startup configuration file the first time you use the save [ safely ] [ force ]
command to save the running configuration to the file.
The backup file is named in the _old-filename_bak.cfg format. For example, if the old configuration file
is named config.cfg, the backup file is named _config_bak.cfg.
If the backup attempt fails on the device, choose one of the following failure handling actions at prompt:
Give up saving the configuration—The system does not save the running configuration on the
•
device.
Overwrite the configuration file—The system uses the running configuration to overwrite the old
•
configuration file on the device without backing up the file.
Make sure the storage medium has enough space for the backup configuration file and the new
next-startup configuration file.
To load the backup configuration file after a software downgrade, specify the backup file as the
next-startup configuration file.

Specifying a configuration file for the next startup

You can specify a .cfg configuration file as the startup configuration file to be used at the next startup
when you use the save command to save the running configuration to it.
Alternatively, perform the following task in user view to specify the next-startup configuration file:
Task
Specify the next-startup
configuration file.
