Port Extenders (PEs)
The C9010 switch supports the IEEE 802.1BR fabric protocol to expand the port density of the chassis,
using C1048P port extenders. In this deployment, the C9010 operates as a controlling bridge for the
C1048P. The C1048P functions as a remote line card that is physically connected to, and provisioned by,
a C9010 over 10GbE links according to the IEEE 802.1BR standard.
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.
