Factory Reset

Information About Factory Reset

Factory reset removes all customer-specific data added to a device since its shipping. The erased data includes configurations, log files, boot variables, core files, and credentials such as Federal Information Processing Standard-related (FIPS-related) keys. The device returns to its default license configuration after a factory reset.

Note: The factory reset is performed through an IOS CLI. A copy of the running image is backed up and restored after the reset.
