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. The purpose of supervisory packets is to allow packets that would be otherwise blocked to be forwaded for special purposes. For example the BPDU packets that sent during link start up must also be seen on ports in a blocking state. This allows the bridge software to remove loops in the fabric.
