Fix a Live Device Configuration (Restore)
CCM performs the configuration restore operation in either overwrite or merge mode, as described in
the following. As part of restore operation, the configuration files are backed up again after the restore
procedure is complete.
• Overwrite mode—CCM overwrites the existing configuration on the device with a configuration file
from the archive. After the restore operation is performed, the device configuration is identical to
the configuration that was chosen from the archive.
The following devices support overwrite mode:
Cisco Catalyst 3550 Series Switches
Cisco Catalyst 3560 Series Switches
Cisco Catalyst 3750 Series Switches
Cisco Catalyst 6500 Series Switches (IOS)
Cisco 800 Series Routers
Cisco 1800 Series Routers
Cisco 1700 Series Routers
Cisco 2600 Series Multiservice Platform Routers
Cisco 2800 Series Integrated Services Routers
Cisco 3700 Series Multiservice Access Routers
Cisco 3800 Series Integrated Services Routers
Cisco 7200 Series Routers
Cisco 7600 Series Routers
Cisco 10000 Series Routers
Cisco 12000 Series Routers (IOS)
Cisco ASR 901 Series Routers
Cisco ASR 903 Series Routers
Cisco MWR 2941 Router
For Cisco IOS XR devices, the restore operation rolls back the configuration file to a commit ID
associated with the selected archived configuration. If no commit ID is associated with the selected
archived version, the restore will fail.
For all other devices supported by CCM, restore operations in overwrite mode is not supported.
• Merge mode—CCM merges the selected configuration file from the archive with the configuration
on the device. New commands in the archived version—that is, commands that are not in the
device’s current configuration—are pushed to the device. After the restore operation, the device
configuration file retains its original commands, but it also contains new commands from the
archived version.
Note The restore operation is not applicable to boot configuration files on Cisco ASR 5000 series devices.
By default, Prime Network uses the restore mode setting (overwrite or merge) that is specified in the
Configuration Management Settings page (see Change Configuration Managemennt Global Settings,
page 4-61. However, you can modify the default mode while scheduling the restore operation. If you
have selected the overwrite mode, you can use the Use Merge on Failure option to restore the files in
merge mode, if overwrite mode fails.
If you select the devices by checking the check box next to Devices (in the table headline), only the first
100 devices in the first page are selected. Click Next to move to the next 100 devices. If you filter the
devices based on a parameter, only the filtered details are displayed, and by default, no row is selected.
