Overview

Device zeroization lets you remove all user files from flash storage, including solid-state drives (SSDs). User files cannot be retrieved after the zeroization is complete.

NOTE:

Zeroization can occur in both AOS-CX and Service OS. This section covers zeroization and AOS-CX. For information about zeroization and Support OS, see erase zeroize.

Zeroization preserves the primary and secondary software images on the SSD. Zeroization also preserves manufacturing information.

The sensitive user files stored on an SSD or SPI flash/EEPROM storage or both include:

Switch configurations.
System generated private keys.
User installed private keys.
Admin/operator password files.

NOTE:

For more information on password requirements, see Password requirements in the Security Guide.
