Log in

Use this procedure to restore the NCS 1004 to its factory default settings by erasing all system configuration, including usernames, passwords, and IP addresses.

Restore the NCS 1004 to its original factory configuration, removing all previous settings and user information.

You can restore the factory settings on the NCS 1004. The entire system configuration, including usernames, passwords, and IP addresses, is removed. You can perform this operation only through the console port and not on the management interface. To restore NCS 1004 to factory settings, use the commit replace command. After the commit replace operation completes, you must perform the IOS XR reload operation.

The commit best-effort command merges the target configuration with the running configuration and commits only valid changes (best effort). Some configuration changes might fail due to semantic errors.

Note

Perform this operation only on the console port.

.
Follow these steps to restore factory settings on the NCS 1004:

Procedure
