The following table defines parameters for the software command.
| Variable | Value | 
|---|---|
| activate WORD<1-99> | Copies the software version to the boot flash file. When you use the software activate command, the system checks for hardware dependencies and prevents a downgrade if it detects a dependency. For example, if a hardware component has a minimum software version dependency, you cannot downgrade to an incompatible software version or install the hardware component in a chassis that runs an incompatible software version. | 
| add WORD<1-99> | Unpacks a software release <version>. | 
| -y Note: Exception: only supported on 5420 Series and 5520 Series. | Suppresses the confirmation message to automatically overwrite the non-primary image. If you omit this parameter, you must confirm the action to overwrite the non-primary image. |
