Example for Configuring a Generalflow Test in a Native Ethernet Scenario (RFC 2544)

This section describes how to configure a generalflow test in a native Ethernet scenario. A generalflow test is used to monitor the native Ethernet network performance.

Networking Requirements

A generalflow test needs to be configured to monitor the performance of an Ethernet virtual connection (EVC) between Device A and Device B on the network shown in Figure 1.

Figure 1 General flow test in a native Ethernet scenario

Interfaces 1 and 2 in this example are GE0/1/1, and GE0/1/2, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure reflector Device B to loop traffic with a specified destination MAC address through reflector interface GE 0/1/1 to the initiator.
Configure initiator Device A and test the throughput, latency, and packet loss rate.
Configure Device C's interface to join the specified VLAN.

Data Preparation

To complete the configuration, you need the following data:

On reflector Device B: MAC address (00-e0-fc-12-34-56) of the interface directly connected to UNI-B
On initiator Device A:
- Destination MAC address (00-e0-fc-12-34-56) of the interface directly connected to UNI-B
- Throughput test parameters: upper rate threshold (100000 Kbit/s), lower rate threshold (10000 Kbit/s), throughput precision (1000 Kbit/s), packet loss rate (81), interval (5s) at which test packets are transmitted at a specified rate, data size (70 bytes) of each test packet, and test duration (100s)
- Delay test parameters: packet rate (99000 Kbit/s), test duration (100s), and interval (5s) at which the initiator sends test packets
- Packet loss rate test parameters: packet rate (99000 Kbit/s), and test duration (100s)

Procedure

Configure reachable Layer 2 links between the initiator and reflector and add Layer 2 interfaces to VLAN 10. For configuration details, see "Configuration Files" in this section.

Configure the reflector.

<DeviceB> system-view
[~DeviceB] nqa reflector 1 interface gigabitethernet 0/1/1 mac 00-e0-fc-12-34-56 vlan 10

Configure the initiator to conduct a throughput test and check the test results.

Configure the initiator to conduct a latency test and check the test results.

Configure the initiator to conduct a packet loss rate test and check the test results.

[*DeviceA] nqa test-instance admin loss
[*DeviceA-nqa-admin-loss] test-type generalflow
[*DeviceA-nqa-admin-loss] measure loss
