Example for Configuring TWAMP Light Based on Eth-Trunk Member Interfaces
This section provides an example for configuring TWAMP Light based on Eth-Trunk member interfaces.
Networking Requirements
On the IP network shown in Figure 1, DeviceA functions as the Controller, and DeviceB functions as the Responder. Multiple member links of an Eth-Trunk are bundled between DeviceA and DeviceB.
- DeviceA: sends and receives packets over a test session, collects and calculates performance statistics, and reports the statistics to the performance management system.
- DeviceB: responds to the packets received over a test session.
Figure 1 TWAMP Light networking
In this example, interfaces 1 and 2 represent GE 0/1/0 and GE 0/1/8, respectively.
Configuration Roadmap
The configuration roadmap is as follows:
- Configure an IP address and a routing protocol for each interface so that all the devices can communicate at the network layer.
- Create an Eth-Trunk interface on DeviceA and DeviceB, and then add Ethernet physical interfaces to each Eth-Trunk interface.
- Configure the TWAMP Light Responder on DeviceB.
- Configure the TWAMP Light Controller on DeviceA.
- Configure the Controller to send statistics to the performance management system through telemetry.
Data Preparation
To complete the configuration, you need the following data:
- Responder DeviceB
- IP address of the Eth-Trunk interface: 10.2.2.2
- UDP port number: 2010
- Controller DeviceA
- IP address of the Eth-Trunk interface: 10.1.1.1
- UDP port number: 2001
- Performance management system
- IP address: 192.168.100.100
- gRPC port number: 10001
Procedure
- Configure an IP address and a routing protocol for each interface so that all the devices can communicate at the network layer. The configuration procedure is not provided here.
- Create an Eth-Trunk interface and add Ethernet physical interfaces to the Eth-Trunk interface. The following example uses the configuration on DeviceB. The configuration roadmap on DeviceA is the same as that on DeviceB.
