Table of L2 ACL binding to port. - One cannot bind Layer 2 ACLs and Layer 3 ACLs to the same port. However, one can configure a port to use Layer 2 ACLs, and another port on the same device to use Layer 3 ACLs. - In general, Layer 2 ACLs cannot be bound to virtual interfaces, unlike L3 ACLs. - One cannot modify an existing Layer 2 ACL clause. For that, one must unbind the ACL, delete it and make a new clause.
