MAC sets added to NSX edge gateways are groups of MAC addresses to which the firewall rules apply. You can use MAC sets for access control, filtering, and security purposes within your local network. Combining multiple objects into MAC sets helps you to reduce the total number of distributed firewall rules to be created.
