The NPU-50 on the CX600-X1-M4 processes service data of the entire system.
The NPU-50 has a 50-Gbit/s forwarding capability in each direction, and all subcards exchange
data through the NPU-50.
You can install only one NPU-50 on the chassis of the CX600-X1-M4.
The NPU-50 consists of the following planes:
l
Control and management plane
Through the management channels between MPUs and the NPU-50, the MPUs can manage
the subcards, and transmit routing protocol data.
