Configuring cloud connections

About cloud connections

A cloud connection is a management tunnel established between a local device and the H3C Oasis

server. It enables you to manage the local device from the H3C Oasis server without accessing the

network where the device resides.

Multiple subconnections

After a local device establishes a connection with the H3C Oasis server, service modules on the

local device can establish multiple subconnections with the microservices on the H3C Oasis server.

These subconnections are independent from each other and provide separate communication

channels for different services. This mechanism avoids interference among different services.

Cloud connection establishment

As shown in Figure 1, the cloud connection between the device and the H3C Oasis server is

established as follows:

1. The device sends an authentication request to the H3C Oasis server.

2. The H3C Oasis server sends an authentication success packet to the device.

The device passes the authentication only if the serial number of the device has been added to

the H3C Oasis server. If the authentication fails, the H3C Oasis server sends an authentication

failure packet to the device.

3. The device sends a registration request to the H3C Oasis server.

4. The H3C Oasis server sends a registration response to the device.

The registration response contains the uniform resource locator (URL) used to establish a

cloud connection.

5. The device uses the URL to send a handshake request (changing the protocol from HTTP to

WebSocket) to the H3C Oasis server.

6. The H3C Oasis server sends a handshake response to the device to finish establishing the

cloud connection.

7. After the cloud connection is established, the device automatically obtains the subconnection

URLs and establishes subconnections with the H3C Oasis server based on the service needs.

Configuring the H3C Oasis server

For a successful cloud connection establishment, add the serial number of the device to be managed

to the H3C Oasis server. For more information about the H3C Oasis server settings, see the

installation guide for the H3C Oasis server.

Configuring the local device

About this task

You can specify a domain name for the H3C Oasis server and log in to the server through the domain

name on a remote PC to manage the local device.

If the local device does not receive a response from the H3C Oasis server within three keepalive

intervals, the device sends a registration request to re-establish the cloud connection.

To prevent NAT entry aging, the local device sends ping packets to the H3C Oasis server

periodically.

Restrictions and guidelines

Reduce the ping interval value if the network condition is poor or the NAT entry aging time is short.

Procedure

1. Enter system view.

system-view

2. Configure the domain name of the H3C Oasis server.

cloud-management server domain domain-name

By default, the domain name of the H3C Oasis server is not configured.

3. (Optional.) Set the keepalive interval.

cloud-management keepalive interval

By default, the keepalive interval is 180 seconds.

4. (Optional.) Set the ping interval.

cloud-management ping interval

By default, the ping interval is 60 seconds.

5. (Optional.) Specify the TCP port number used to establish cloud connections.

cloud-management server port port-number

By default, the TCP port number used to establish cloud connections is 19443.

Unbinding the device from the Oasis server

About this task

A device can be registered on the Oasis server by only one user.

To register a device that has been registered by another user, you need to take the following steps:

1. Obtain a verification code for device unbinding from the Oasis server.

2. Execute the command on the device for sending the verification code to the Oasis server.

3. Register the device on the Oasis server.

Procedure

1. Enter system view.

system-view

2. Send the verification code for device unbinding to the Oasis server.
