Testing PWs

Testing PWs

You need to test and ensure the connectivity and performance of pseudo wires (PWs) on a network that carries packet services, to ensure normal service transmission.

Testing PW Connectivity Using PW Ping

The PW ping function in MPLS PW OAM allows you to check PW connectivity with one click. No instrument is required in the test.

Prerequisites

  • A PWE3 service has been created. For details on how to create a PWE3 service, see Managing PWE3 Services.
    NOTE:

    Before managing a PWE3 service that is created on a per-NE basis, you need to search for the PWE3 service.

  • You are an NM user with Administrators rights or higher.

Background Information

Only certain boards on the OptiX OSN equipment support MPLS OAM. For details about applicable boards, see Availability of MPLS OAM (Packet) in the Feature Description.

Procedure

  1. Choose Service > PWE3 Service > Manage PWE3 Service from the main menu.
  2. In the dialog box that is displayed, set filter conditions; for example, set Protocol Type to PW APS Protection. Then, click Filter. Query all PWE3 services that meet the filter conditions.
  3. Right-click the PWE3 service to be tested and choose Test and Check from the shortcut menu. The Test and Check dialog box is displayed.
  4. Use the ping function to check whether the PW is available.
    1. On the Diagnosis Option pane (located in the lower left area), select VCCV ping and click . In the Advanced Parameter dialog box that is displayed, set PW ping parameters and click OK.

    2. In the lower right area of the window, click Run.
    3. View test results in the Result window. You can also view the number of packets transmitted and received on the PW, packet loss ratio, and delay information by clicking Details in the Check Result pane.

      NOTE:
      If the number of transmitted packets and the number of received packets are different, packet loss has occurred. Perform a VCCV traceroute test to locate the fault.

  5. Optional: Perform a VCCV traceroute test on the affected PW to locate the fault.
    1. Click the Configuration tab.
    2. On the Diagnosis Option pane (located in the lower left area), select VCCV traceroute and click . In the Advanced Parameter dialog box that is displayed, set VCCV ping parameters and click OK.

    3. In the lower right area of the window, click Run.
    4. View test results in the Result window. You can also view running status of the PW by clicking Details in the Check Result pane.

Follow-up Procedure

If the PW test fails, see Handling PW Faults for troubleshooting measures.
