• Restoring configuration files from an external device to the device.
When restoring a configuration file to the Running Configuration, the imported file
adds any configuration commands that did not exist in the old file and overwrites
any parameter values in the existing configuration commands.
When restoring a configuration file to the Startup Configuration or a backup
configuration file, the new file replaces the previous file.
When restoring to Startup Configuration, the device must be rebooted for the
restored Startup Configuration to be used as the Running Configuration. You can
reboot the device by using the process described in the Rebooting the Device
section.
Configuration File Backwards Compatibility
When restoring configuration files from an external device to the device, the
following compatibility issues might arise:
• Change Queues Mode from 4 to 8—Queue-related configurations must be
examined and adjusted to meet QoS objectives with the new Queues
mode. See the CLI Reference Guide for a listing of these QoS commands.
• Change Queues Mode from 8 to 4—Queue-related configuration
commands that conflict with the new Queues mode are rejected, meaning
that the download of the configuration file fails. Use the System Mode and
Stack Management page to change the Queues mode.
• Change the System Mode—If the System mode is contained in a
configuration file that is downloaded to the device, and the file's System
mode matches the current System mode, this information is ignored.
Otherwise, if the System mode is changed, the following cases are
possible:
- If the configuration file is downloaded onto the device (using the
Download/Backup Configuration/Log page), the operation is aborted,
and a message is displayed indicating that the System mode must be
changed in the System Mode and Stack Management page.
- If the configuration file is downloaded during an automatic configuration
process, the Startup Configuration file is deleted and the device reboots
automatically in the new System mode. The device is configured with an
empty configuration file. See DHCP Auto Configuration.
• See Configuration After Reboot for a description of what happens when
the stacking modes are changed.
