1.1 Overview
The CX600-X1-M4 is a high-end network device developed by Huawei. This device is based
on the VRP and applies to the access, convergence, and transmission of Metro services.
The CX600-X1-M4 has great capabilities for network access, Layer 2 switching, and EoMPLS
transmission, and supports a wide range of high-speed and low-speed interfaces. In addition, the
CX600-X1-M4 supports triple-play of voice, video, and data services and can bear 2G, 3G, and
LTE services simultaneously. The CX600-X1-M4 can be deployed together with Huawei NE,
CX, and ME series products to build a hierarchical Metro Ethernet network that offers extensive
services.
1.1.1 System Overview
System Overview
Being equipped with a centralized routing engine and NP forwarding structure, the CX600-X1-
M4 has a great capacity and can provide diverse services.
The CX600-X1-M4 has an integrated chassis that can be installed independently. The main parts
of the CX600-X1-M4 such as MPUs, NPUs, PICs, fan modules, and PSUs are hot-swappable.
Figure 1-1 shows the outline of the CX600-X1-M4. The CX600-X1-M4 provides one slot for
the NPU and four slots for PICs. The network process unit on the CX600-X1-M4 is NPU. All
the PICs switch data with each other through the NPU.

System Architecture
The logical architecture of the CX600 consists of the following planes: data plane, control and
management plane, and monitoring plane, as shown in Figure 1-2. The data plane processes and
switches data packets quickly and smoothly; the control and management plane, as the core of
the system, controls and manages the system; the monitoring plane monitors the ambient
operating conditions.
