IoT Platform:Create a JT/T 808 cloud gateway

更新時間:Sep 12, 2023

If you want to use a JT/T 808 cloud gateway to connect a device to IoT Platform, you must add a cloud gateway in the IoT Platform console. This topic describes how to create a JT/T 808 cloud gateway.

Prerequisites

An Exclusive Enterprise Edition instance is purchased. For information about how to purchase an instance, see Purchase Enterprise Edition instances.

Background information

For information about how to use a JT/T 808 cloud gateway to connect a device to IoT Platform, see JT/T 808 gateways.

Add a cloud gateway

  1. Log on to the IoT Platform console.

  2. On the Overview tab, click the Exclusive Enterprise Edition instance that you want to manage.

  3. In the left-side navigation pane, choose Devices > Gateway. On the page that appears, click Add Gateway.

  4. Configure the parameters based on the on-screen instructions and click Next. The following table describes the parameters.

    Parameter

    Description

    Gateway Name

    The name of the gateway. The name must be unique in the instance. The name must be 4 to 30 characters in length and can contain letters, digits, and underscores (_).

    Protocol

    Select JT/T 808.

    Custom Port Number

    Valid values: 1024 to 65535. Default value: 7999.

    Authentication Type

    One-party verification

    If you select this option, you must import the verification information of a device to IoT Platform. The verification information includes the Manufacturer ID, Terminal Model, and Terminal ID of the device. IoT Platform verifies the device based on the verification information.

    Third-party Certification

    • Alibaba Cloud Function Compute: If you select this option, you must configure the Device-verified FC Service, Device-verified FC Function, and Authorize parameters. You can select an existing Function Compute function or create a new function for device verification. The input and output parameters of the function that you create must meet specific requirements. You can specify a custom function name. For information about the requirements on the input and output parameters of the device verification function, see Table 1 Device registration parameters, Table 2 Device verification parameters, and Table 3 Device deregistration parameters.

      • Click Create Service to go to the Function Compute console and create a service. For information about Function Compute services, see Manage services.

      • Click Create Function to go to the Function Compute console and create a function. For information about Function Compute functions, see Manage functions.

      • If the AliyunIOTAccessingFCRole role is not available, click Create RAM Role to go to the RAM console and create the role. For information about how to create a RAM role and grant permissions to the role, see Create a RAM role.

    Transmission Protocol

    TCP

    If you use Transmission Control Protocol (TCP) to connect a device, we recommend that you do not connect the device over the Internet. To ensure security, establish a connection over a leased line.

    Important

    If you use TCP to connect a device, you do not need to configure certificates. After you complete all configurations in the Basic Information step, click OK to create the gateway.

    TLS

    If you connect devices to IoT Platform over Transport Layer Security (TLS), you can enable server-side one-way verification, Online Certificate Status Protocol (OCSP) for devices, two-way secure connections between devices and servers, and other features.

    • Enable X.509 certificate-based device verification. Valid values of the Enable OCSP parameter:

      • Disabled

      • OCSP Verification for Server Certificate

      • OCSP Verification for Client Certificate

      • Client and Server-side OCSP Verification

    • Disable X.509 certificate-based device verification. Valid values of the Enable OCSP parameter:

      • Disabled

      • OCSP Verification for Server Certificate

    Note
    • Online Certificate Status Protocol (OCSP) is an Internet protocol that is used by a certificate authority (CA) to check the revocation status of a certificate.

    • When a client sends a message to a server, the server performs OCSP verification on the client certificate. If the client certificate is revoked, the server closes the connection.

    • The default time to live (TTL) of cached OCSP information ranges from 5 minutes to 1 hour. After the cached OCSP information expires, server-side OCSP stapling does not take effect until the OCSP information is re-obtained.

  5. Complete the Certificate Configuration step and click OK.

    Configure certificates

    Important
    • If you select TCP as the transmission protocol, you do not need to configure certificates.

    • The certificates that are configured in this step are Privacy Enhanced Mail (PEM) files.

    1. You must configure the Server Certificate and Private Key of Server Certificate parameters.

    2. If you enable X.509 certificate-based device verification, you must configure the Device Root Certificate parameter.

    3. If you set the Enable OCSP parameter in the previous step to OCSP Verification for Server Certificate or Client and Server-side OCSP Verification, you must set the Trusted Certificate parameter to the server root certificate in this step.

  6. View the information about the gateway that you created on the Gateway page, including the name, ID, gateway URL, status, and associated product.

    Important

    You must record the gateway URL. When you connect a device to IoT Platform over JT/T 808, you must replace the JT/T 808 endpoint with the gateway URL. You can specify the gateway URL as the JT/T 808 endpoint or configure a CNAME record to resolve the JT/T 808 endpoint to the gateway URL.

What to do next

  • The first time you use the cloud gateway whose Authentication Type parameter is set to Third-party Certification to connect a device to IoT Platform, IoT Platform automatically combines the values of the manufacturer, deviceModel, and deviceId parameters in the ${manufacturer}_${deviceModel}_${deviceId} format as the DeviceName to create a device.

  • After you create a cloud gateway whose Authentication Type parameter is set to One-party Verification, you must import the verification information of devices to add the devices to the related gateway product. For more information, see Add multiple devices.
