Example: Configure an RFC 2544-Based Benchmarking Test for Layer 3 IPv4 Services

date_range 01-Dec-23

arrow_backward

arrow_forward

This example shows how to configure the benchmarking test for a Layer 3 IPv4 service.

Note:

This example is not applicable for ACX5448, ACX5048, and ACX5096 routers.

Requirements

This example uses the following hardware and software components:

An ACX Series router
Junos OS Release 12.3X53 or later

Overview

Consider a sample topology in which a router, Router A, functions as an initiator and terminator of the test frames for an RFC 2544-based benchmarking test. Router A is connected over a Layer 3 network to another router, Router B, which functions as a reflector to reflect back the test frames it receives from Router A. IPv4 is used for transmission of test frames over the Layer 3 network. This benchmarking test is used to compute the IPv4 service parameters between Router A and Router B. Logical interfaces on both the routers are configured with IPv4 addresses to measure the performance attributes, such as throughput, latency, frame loss, and bursty frames, of network devices for the IPv4 service.

Figure 1 shows the sample topology to perform an RFC 2544 test for a Layer 3 IPv4 service.

Figure 1: RFC 2544-Based Benchmarking Test for a Layer 3 IPv4 Service

Configuration

In this example, you configure the benchmarking test for a Layer 3 IPv4 service that is between interface ge-0/0/0 on Router A and interface ge-0/0/4 on Router B to detect and analyze the performance of the interconnecting routers. You do not configure a test profile on Router B, because it operates as a reflector. You must configure the reflector (Router B) before you configure the initiator (Router A), because the reflector needs to be already configured and the tests running before you start tests on the initiator. If you start the tests on the initiator first, then all the packets sent are lost until you start the tests on the reflector.

Configure Benchmarking Test Parameters on Router B

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode.

To configure the test parameters on Router B:

In configuration mode, go to the [edit interfaces] hierarchy level:
```
[edit]
user@RouterB# edit interfaces
```
Configure the interface on which the test must be run.
```
[edit interfaces]
user@RouterB# edit ge-0/0/4
```
Configure a logical unit and specify the protocol family as inet.
```
[edit interfaces ge-0/0/4]
 user@RouterB# edit unit 0 family inet
```

Specify the address for the logical interface.

content_copy zoom_out_map
[edit interfaces ge-0/0/4 unit 0 family inet]
user@RouterB# set address 192.0.2.2/24

Enter the up command to go the previous level in the configuration hierarchy.
```
[edit interfaces ge-0/0/4 unit 0 family inet]
user@RouterB# up
```
Go to the top level of the configuration mode.
```
[edit interfaces ge-0/0/4 unit 0]
user@RouterB# top
```
In configuration mode, go to the [edit services] hierarchy level.
```
[edit]
user@RouterB# edit services
```
Configure a real-time performance monitoring service (RPM) instance.
```
[edit services]
user@RouterB# edit rpm
```
Configure an RFC 2544-based benchmarking test for the RPM instance.
```
[edit services rpm]
user@RouterB# edit rfc2544-benchmarking
```
Define a name for the test—for example, test1. The test name identifier can be up to 32 characters in length.
```
[edit services rpm rfc2544-benchmarking]
user@RouterB# edit tests test-name test1
```
Specify the logical interface, ge-0/0/4.0, on which the RFC 2544-based benchmarking test is run.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set test-interface ge-0/0/4.0
```
Specify reflect as the test mode for the packets that are sent during the benchmarking test.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set mode reflect
```
Configure the address type family, inet, for the benchmarking test.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set family inet
```
Configure the destination IPv4 address for the test packets as 192.0.2.2. The destination IPv4 address configured on the reflector must match the destination IPv4 address configured on the initiator. If you configure 192.0.2.1 instead, you get this error message: error: test test1 - Could not determine local interface for address 192.0.2.1.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set destination-ipv4-address 192.0.2.2
```
Specify the UDP port of the destination to be used in the UDP header for the generated frames as 4001.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set destination-udp-port 4001
```

Configure the source IPv4 address for the test packets.

content_copy zoom_out_map
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# set source-ipv4-address 192.0.2.1

Go to the top level of the configuration mode.

content_copy zoom_out_map
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterB# top

Commit the configuration.
```
[edit]
user@RouterB# commit
```

Confirm the configuration. If the output does not contain the configuration below, repeat the configuration instructions in this example to correct it.

content_copy zoom_out_map
[edit interfaces]
  ge-0/0/4 {
      unit 0 {
          family inet {
              address 192.0.2.2/24;
          }
       }
  }

  [edit services rpm]
  rfc2544-benchmarking {
      # Note, When in reflector mode, test profile is not needed
      tests {
          test-name test1 {
              test-interface ge-0/0/4.0;
              mode reflect;
              family inet;
              destination-ipv4-address 192.0.2.2;
              destination-udp-port 4001;
              source-ipv4-address 192.0.2.1
          }
      }
  }

Exit to operational mode.
```
[edit]
user@RouterB# exit
user@RouterB>
```
Start the benchmarking test on the reflector.
```
user@RouterB> test services rpm rfc2544-benchmarking test test1 start
```
Once you configure the initiator (Router A), you can start the test on the initiator, and the initiator starts sending packets to the reflector. Once the test is successfully completed at the initiator, you can stop the test at the reflector by entering the test services rpm rfc2544-benchmarking test test1 stop command in operational mode.

Configure Benchmarking Test Parameters on Router A

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode.

```
Specify the test mode for the packets that are sent during the benchmarking test as initiate and terminate.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# set mode initiate-and-terminate
```
Configure the address type family, inet, for the benchmarking test.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# set family inet
```

Configure the destination IPv4 address for the test packets.

content_copy zoom_out_map
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# set destination-ipv4-address 192.0.2.2

Specify the UDP port of the destination to be used in the UDP header for the generated frames as 4001.
```
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# set destination-udp-port 4001
```

content_copy zoom_out_map
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# set source-ipv4-address 192.0.2.1

Go to the top level of the configuration mode.

content_copy zoom_out_map
[edit services rpm rfc2544-benchmarking tests test-name test1]
user@RouterA# top

Commit the configuration.
```
[edit]
user@RouterA# commit
```

Confirm the configuration. If the output does not contain the configuration below, repeat the configuration instructions in this example to correct it.

content_copy zoom_out_map
[edit]
user@RouterA# show
[edit interfaces]
  ge-0/0/0 {
      unit 0 {
          family inet {

          }
       }
  }

  [edit services rpm]
  rfc2544-benchmarking {
      profiles {
          test-profile throughput {
              test-type throughput
              packet-size 64;
              bandwidth-kbps 1000;
          }
      }

      tests {
          test-name test1 {
              test-profile throughput;
              interface ge-0/0/0.0;

              source-ipv4-address 192.0.2.1
          }
      }
  }

Exit to operational mode.
```
[edit]
user@RouterA# exit
user@RouterA>
```
Start the benchmarking test on the initiator.
```
user@RouterA> test services rpm rfc2544-benchmarking test test1 start
```
After the test successfully completes, it automatically stops at the initiator. Once the test is successfully completed at the initiator, you can stop the test at the reflector by entering the test services rpm rfc2544-benchmarking test test1 stop command on Router B in operational mode.

Results

If you have not done so already, confirm your configuration on Router A and Router B by entering the show command in configuration mode at the [edit interfaces] and [edit services rpm] hierarchy levels. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.
