Why each option
When performing a software downgrade on a Cisco Nexus 9000 Series switch, the 'install all ... impact' command displays the features that will be automatically removed due to incompatibility with the older software version. This allows engineers to understand the functional changes before proceeding.
The 'install all ... impact' command, when used for a software downgrade on a Cisco Nexus 9000 Series switch, analyzes the target software version and reports which features supported by the current higher version are incompatible with the older version and will therefore be automatically removed or become non-operational upon downgrade.
The 'install all ... impact' command primarily focuses on software feature compatibility and operational changes, not direct incompatibility between the bootflash file and the switch hardware.
While it deals with software incompatibility, the specific output highlights the *features* that are affected and removed, rather than just stating general file incompatibility with the software.
The question specifies a 'software downgrade' and the command provides detailed information about specific feature removal, which is more precise than a generic 'impact of an in-service software upgrade and chassis reload'.
