L3 Traffic on Dell Switch Z9100

Hi,
we have Dell switch Z9100 that works as a Leaf switch and caries L2 traffic. Some customers also use these switches as L3 and carry L3 traffic.

Question:

How can I check on the Dell Leaf switches if they carry L2 and L3 traffic?

How to identify if switch carries L3 traffic? Are there any commands that can be execute and what to look for in the output?

Thank you,
