Hello all. Does anyone know 1)whether the logs are definitive on spoofing taking place, and 2)whether devices would be blocked if this option is enabled?   I hesitate to enable as I reviewed our logs which show laptops on our (flat) network are being flagged. However, these are company laptops that are on the corp wifi, which have obtained the correct DHCP.   I already read the article for Meraki MXs Anti-spoofing.
