Description
1. The control plane performs functions such as protocol processing, service processing, route calculation, forwarding control, service scheduling, traffic statistics, and system security. 2. The management plane performs functions such as system running status monitoring, environment monitoring, log and alarm processing, system loading, and system upgrade. For example, a switch can be divided into the following three planes (see the network device plane division in RFC7426):
Switch forwarding plane: The forwarding plane provides high-speed non-blocking data channels and implements service switching between service modules. The basic task of a switch is to process and forward various types of data on different ports of the switch. Various specific data processing and forwarding processes such as L2/L3/ACL/QoS/ multicast/security protection belong to the task category of the switch forwarding plane. Switch control plane: The control plane performs functions such as protocol processing,

service processing, routing calculation, forwarding control, service scheduling, traffic statistics, and system security. The control plane of the switch controls and manages all network protocols. The control plane provides various network information and forwarding query entries required by the data plane before data processing and forwarding. Management plane of the switch: The management plane performs functions such as system running status monitoring, environment monitoring, log and alarm processing, system loading, and system upgrade. The management plane of a switch enables network administrators to use TELNET, WEB, SSH, SNMP, and RMON to manage devices, and supports, understands, and executes commands for setting various network protocols on network devices. Management plane The parameters of various protocols on the control plane must be configured in advance, and the control plane can be intervened when necessary. Some Huawei products combine functions into the data plane, management plane, and monitoring plane.
Control plane
The control plane of the device consists of the main control board and the management unit of the interface board.
The control management plane completes the control and management functions of the system and is the central nervous system of the entire system. The control/plane completes the protocol processing, service processing, routing calculation, and forwarding control of the system. Service scheduling The control plane of a switch is used to control and manage the running of all network protocols. The control plane provides various network information and forwarding query entries required by the data plane before data processing and forwarding.
