IEEE 802.1BR

The IEEE 802.1BR protocol allows a controlling bridge to use IEEE LAN technologies to discover and manage
port extenders.
The following illustration shows how a controlling bridge connects through an automatically established port
channel (auto-LAG) to an uplink port on one or more port extenders.
