Understanding Plug-and-Play Deployment

Understanding Plug-and-Play Deployment

Basic Concepts

  • Cloud management platform: is a core component in the Huawei Cloud Managed Network Solution. This component uniformly manages Huawei network devices, such as access routers (ARs), switches, and firewalls. Plug and play of network devices can be implemented through the cloud management platform.

  • Registration center: is a main component in the Huawei Cloud Managed Network Solution. This component allows querying device management mode and home cloud management platform. According to the query result, a device determines whether to change to the cloud-based management mode and which cloud management platform it must register with. Currently, ARs work in cloud-based management mode by default.

Process of Implementing Cloud-based Management on ARs

In the Huawei Cloud Managed Network Solution, there are three phases from managed AR deployment to unified device management on the cloud management platform.

  1. ARs obtain the cloud management platform's address information.

    This phase is the preparation phase in cloud-based management. Routers must first obtain the cloud management platform's URL/IP address and port number. Now these routers are ready to communicate with the cloud management platform. Two methods are available to obtain the cloud management platform's address information, as described in Table 6-1.

    Scenario

    Priority

    Through a DHCP server Option 148 is configured on a DHCP server to carry the cloud management platform's address information. Routers obtain the information through the DHCP server. This method applies to the cloud managed networks on which devices cannot communicate with the Huawei device registration query center. The cloud management platforms of these networks are often built by enterprises.

    High priority. This method is preferred if routers can use multiple methods to obtain the cloud management platform's address information.

    Through the registration center

    Routers use the Huawei device registration query center's URL/IP address and port number that are preconfigured or obtained through a software upgrade to access the registration center and then obtain the cloud management platform's address information based on their ESNs or MAC addresses.

    This method applies to the cloud managed networks on which devices can communicate with the Huawei device registration query center. The cloud management platforms of these networks are the Huawei public cloud platform.

    Low priority

  2. ARs register with the cloud management platform for authentication.

    Routers obtain the cloud management platform's URL/IP address and port number, register with the cloud management platform for authentication, and establish a NETCONF transmission channel. Before the authentication, the cloud management platform needs to import the ESN, device type, and CA certificate of each router. Each router has a local certificate and CA certificate configured before delivery.

  3. ARs are unified managed by the cloud management platform.

    After NETCONF transmission channels are established, the cloud management platform can manage and operate the routers. All the data exchanged between the cloud management platform and routers will be encrypted.

    For details about how the cloud management platform manages routers, see the documentation of the Huawei Cloud Managed Network Solution.

How to Obtain the Cloud Management Platform's Address Information Through a DHCP Server

In the Huawei Cloud Managed Network Solution, DHCP can implement plug-and-play deployment of routers and configure the cloud management platform's address information. In Figure 6-1, administrators need to deploy the DHCP server function on the network egress gateway or deploy an independent DHCP server on the network, and then configure DHCP Option 148, including the cloud management platform's URL/IP address and port number. After a router connects to the network, it initiates a request to the DHCP server to obtain the cloud management platform's address information. After the DHCP server receives the request, it replies with a DHCP packet carrying Option 148. The router receives this DHCP packet, obtains the cloud management platform's URL/IP address and port number, and registers with the cloud management platform for authentication.

How to Obtain the Cloud Management Platform's Address Information Through the Registration Center

In addition to using DHCP, routers can obtain the cloud management platform's address information through the registration center, implementing plug-and-play deployment. In the network shown in Figure 6-2, the cloud management platform needs to establish an HTTP2.0 connection with the registration center and synchronize information about the devices to be managed; routers need to establish an HTTP2.0 connection with the registration center and obtain the cloud management platform's address information.

Figure 6-2  Cloud managed network including the registration center

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

In Figure 6-3, 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.

Figure 6-3  Cloud management platform establishing an HTTP2.0 connection with the registration center

ARs establish an HTTP2.0 connection with the registration center.

The ARs 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 ARs that were delivered earlier and support cloud-based management do not have this URL and port number preconfigured and can be upgraded to the latest software version to obtain default settings. In Figure 6-4, after a router connects to the network, it initiates an HTTP request to the registration center. The router and registration center then establish an HTTP2.0 connection for bidirectional authentication. After the connection is established, the router sends a request packet carrying its ESN and system MAC address to the registration center. The registration center receives the request packet, finds the corresponding ESN in the system, and sends a response packet carrying cloud management platform information to the switch. Based on the information, the router can register with the cloud management platform for authentication.
