Nexus01# show incompatibility-all system n7000-s2-dk9.8.0.1.bin
A software downgrade must be performed on a Cisco Nexus 9000 Series switch. What is displayed by running the command shown?
A. features that are removed automatically from the switch
B. that the bootflash file is incompatible with the switch hardware
C. that the bootflash file is incompatible with the switch software
D. impact of an in-service software upgrade and chassis reload
Answer
The correct answer is A. The “show incompatibility-all system <filename>” command displays features that will be removed automatically from the Cisco Nexus switch when downgrading to the specified software image file.
Explanation
When planning a software downgrade on a Nexus 9000 Series switch, it’s important to check feature compatibility between the current and target software versions. The “show incompatibility-all system” command, when run with the target image filename, will list any features or configurations that are incompatible with the downgrade target version.
The command compares the currently running software version with the specified target image file. It then outputs a list of features that will be automatically removed during the downgrade process because they are not supported or compatible with the older software version.
This allows administrators to proactively plan for the downgrade by reviewing which features will be affected and making any necessary configuration changes or workarounds prior to performing the software downgrade. The output helps ensure a smoother downgrade with fewer unexpected issues.
The other options are incorrect:
- B is wrong because the command checks software compatibility, not hardware compatibility.
- C is wrong because the command is specifically checking the target image’s compatibility when downgrading from the current software version.
- D is incorrect as this command is not used for in-service software upgrades (ISSU) and does not show ISSU impact.
In summary, the “show incompatibility-all system <filename>” command is an essential step when planning a Nexus switch software downgrade. It displays which features will be automatically removed due to incompatibility with the target software version.
