MAC allow list: Only devices with MAC addresses specified in this list will have access to this port. Up to 20 MAC addresses can be defined.
Sticky MAC allow list: The switch will dynamically learn the MAC addresses of devices connected to the port and place the address in the MAC Whitelist. The administrator can define the size of this list. When this list is full, all subsequent devices will be denied access to this port. It can take up to 5 minutes for the learned MAC to appear in dashboard.
Many thanks for all your suggestions and help, awesome community this is. I also had a ticket out with Meraki and they have confirmed no explicit deny MAC address capability just yet on a port by port basis. So Dot1x it is, always good to learn new stuff 😀👍
