how to block mac addresses in cisco 2800 router

Hi,

To block mac addresses you can simply create Mac based ACLs which ranges between 
700 to 799

Example:

access-list 700 deny xxxx.xxxx.xxxx.xxxx
access-list 700 permit yyyy.yyyy.yyyy.yyyy

now you can apply it on interface:

int f0/0
access-group 700 in 
exit
