    In the lead in section 14.3.2.7 Address Lookup Engine (ALE), at the end of the section there is a paragraph that describes what a supervisory packet is for both multicast and unicast. Essentially is saying that an address can be exempted from rate limiting by setting the supervisory bit for the entry in the ALE.

    "Multicast supervisory packets are designated by the super bit in the table entry. Unicast supervisory
    packets are indicated when block and secure are both set. Supervisory packets are not dropped due to
    rate limiting, OUI, or VLAN processing."
