That access list is just cleaning frames being sent to the exchange to  
make sure that weird crap doesn't leak over there. The exchange point  
in question only permits one nominated MAC per port, and will shut  
down the port automagically if it hears more.

access-list 1100 permit 0023.9c72.d700 0000.0000.0000 0000.0000.0000  
ffff.ffff.ffff

That's the complete list, as configured.
