The following configuration is an example of what is needed to run an rfc2544 test.

Services:

labroot@f11-20> show configuration services 

monitoring {
  rfc2544 {
    test-profile gen_profile1 {
      test-type throughput;
      bandwidth 1000 kbps;
      packet-size 1280;
    }
    tests {
      test-name t1 {
        mode initiate-and-terminate;
        family ethernet-switching;
        direction egress;
        test-interface et-0/0/0.1;
        source-mac-address e8:24:a6:7f:35:d8;
        destination-mac-address fc:96:43:1d:86:6b;
        service-type elan;
        test-profile gen_profile1;
      }
    }
  }
}

Interface:

labroot@f11-20> show configuration interfaces  
et-0/0/0 {
  flexible-vlan-tagging;
  encapsulation flexible-ethernet-services;
  unit 1 {
    encapsulation vlan-bridge;
    vlan-id 1;
    family ethernet-switching;
  }
}

In the CLI, the 'test services monitoring rfc2544 test' command can be used to initiate the test:

labroot@f11-20> test services monitoring rfc2544 test t1 start       

Test 't1' with id 4 active

Then, 'show services monitoring rfc2544' referencing active and completed tests can be used to check the status:

labroot@f11-20> show services monitoring rfc2544 active-tests   
Active tests:

And: 

labroot@f11-20> show services monitoring rfc2544 completed-tests      
Test id: 4, Test name: t1
  Test mode: initiate-and-terminate
  Test family: ethernet-switching
  Test state: Completed
  Status: Completed
  Test start time: 2024-05-20 06:30:51 PDT
  Test finish time: 2024-05-20 06:32:20 PDT
