Example for Configuring a Generalflow Test in the IP Gateway Scenario (RFC 2544)

This section describes how to configure a generalflow test in the IP gateway scenario. The generalflow test monitors the Ethernet network performance.

Usage Scenario

A generalflow test needs to be configured to monitor the performance of the Ethernet network shown in Figure 1 between Device A and IP gateway Device B.

Figure 1 General flow test in the IP gateway scenario

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

Configuration Roadmap

The configuration roadmap is as follows:

Configure reflector Device A.
Configure initiator Device B and monitor the latency time.

Data Preparation

To complete the configuration, you need the following data:

On reflector Device A: Set the simulated IP address to 10.1.1.1 (CE's IP address) and the reflector interface to GE 0/1/1.
On initiator Device B:
- Destination IP address: (10.1.1.1) of the CE connected to Device A's GE 0/1/1
- Source IP address: an address that resides on the same network segment as the IP address of the initiator
- Latency test parameters: packet rate (99000 Kbit/s), packet loss ratio (81%), test duration (100s), and interval (5s) at which the initiator sends test packets

Procedure

Configure Layer 2 devices so that Layer 3 routes between the CE and Device B are reachable. For configuration details, see "Configuration Files" in this section.

Configure the reflector.

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