Don't know about the 851 ports but you will not be able to get a layer 2 access list to work on a routed port. I have had to put in bridge groups to get that to work.
A couple of suggestion.
You could put in a static arp so that your mac addresses were always set to ips and then restict the ip addresses allowed to pass though the router.
Another method of doing this is what cisco call LOCK AND KEY. You basically telnet to the router and if you are authenticated then it opens up a path to the network for that IP address for a period of time. I had seen this done with a web browser but don't remember if it was on a IOS based platform.
If you always know the days of the week in advance and it doesn't change a simple time based access list would be the easiest.
Login to the FXOS chassis manager.
