Example for Configuring Dynamic Telemetry Subscription Based on gRPC (IPv4 Collector)

Networking Requirements

As the network scale increases, carriers need to optimize networks and rectify faults based on device information. For example, if a user wants to monitor an interface for a period of time, configure dynamic telemetry subscription. To stop monitoring, tear down the connection. The subscription is automatically canceled and cannot be restored. This avoids the long-term load on devices and simplifies the interaction between users and devices.

As shown in Figure 1, DeviceA supports telemetry and establishes a gRPC connection with the collector. Interface1 of DeviceA needs to be monitored, and data needs to be sent to the collector as required.

Figure 1 Networking of configuring gRPC-based dynamic telemetry subscription

In this example, Interface1 and Interface2 represent GE 0/1/1 and GE 0/1/2, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Create a local user, add the user to the administrator group, and configure the service type of the user.
Set the source IP address to be listened for during dynamic telemetry subscription.
Configure the number of the port to be listened during dynamic telemetry subscription.
Enable the gRPC service.

Data Preparation

To complete the configuration, you need the following data:

IP address of Interface1: 192.168.1.1 (Interface1 on DeviceA and the collector must be routable.)
Number of the port to be listened for: 20000

Procedure

Configure an IP address and a routing protocol for each interface so that all devices can communicate at the network layer.

Create a local user, add the user to the administrator group, and configure the service type of the user.

Set the source IP address to be listened for during dynamic telemetry subscription.

Configure the number of the port to be listened during dynamic telemetry subscription.
```
[*DeviceA-grpc-server] server-port 20000
```

Enable the gRPC service.
