Obtaining the Cloud Management Platform's Address Information Through the Registration Query Center

Before a switch establishes a connection with the registration query center, the switch obtains its management IP address from the DHCP server. The egress gateway shown in Figure 5-5 can also function as a DHCP server.

The cloud management platform establishes an HTTP2.0 connection with the registration query center.

In Figure 5-6, administrators import new device information, including the ESN and device type, into the cloud management platform, and then the cloud management platform initiates an HTTP request to the Huawei device registration query center to upload the information. After the Huawei device registration query center receives the request, it performs bidirectional authentication and establishes an HTTP2.0 connection with the cloud management platform. After the HTTP2.0 connection is established, the cloud management platform uploads the new devices' ESNs and the cloud management platform's address information to the Huawei device registration query center.

Switches establish an HTTP2.0 connection with the registration query center.

All the switches that are delivered most recently and support cloud-based management will have the Huawei device registration query center's URL (register.naas.huawei.com) and port number (10020) preconfigured. The switches that were delivered earlier and support cloud-based management do not have this URL (register.naas.huawei.com) and port number (10020) preconfigured and can be upgraded to the latest software version to obtain default settings. In Figure 5-7, after a switch connects to the network, it initiates an HTTP request to the registration query center. The switch and registration query center then establish an HTTP2.0 connection for bidirectional authentication. After the connection is established, the switch sends a request packet carrying its ESN to the registration query center. The registration query center receives the request packet, finds the corresponding ESN in the system, and sends a response packet carrying cloud management platform's address information to the switch. Based on the information carried in the response packet, the switch changes from the traditional management mode to the cloud-based management mode and restarts. After the restart, the switch sends an HTTP request again and then establishes an HTTP2.0 connection with the registration query center for bidirectional authentication. The switch obtains the cloud management platform's address information based on its ESN to register with the cloud management platform for authentication.
