IS-IS Ether type

Hi fellas,

How to block IS-IS Control Plane packets using access-list. What is the
ether type for IS-IS Packets. Can anyone help me out on how to prevent IS-IS
traffic. We cannot use IP ACL to block IS-IS traffic. So we have to write
MAC ACL to prevent ISIS control packets ?

Thank You
