Testing Tunnels

Testing Tunnels

You need to test and ensure the connectivity and performance of tunnels on a network that carries packet services, to ensure normal service transmission.

Testing Tunnel Connectivity Using MPLS Tunnel Ping

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

Prerequisites

  • MPLS tunnels have been created. For details on how to create MPLS tunnels, see Configuring an MPLS Tunnel.
    NOTE:

    Before managing an MPLS tunnel that is created on a per-NE basis, you need to search for the MPLS tunnel. For details on how to search for MPLS tunnels, see Searching for MPLS Tunnels.

  • 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 > Tunnel > Manage Tunnel from the main menu.
  2. In the dialog box that is displayed, set filter conditions; for example, set Protocol Type to MPLS and set Signaling Type to Static CR. Then, click Filter. Query all MPLS tunnels that meet the filter conditions.
  3. Right-click the tunnel to be tested and choose Test and Check from the shortcut menu. The Test and Check dialog box is displayed.
  4. Use the LSP ping function to test whether the tunnel is available.
    1. On the Diagnosis Option pane (located in the lower left area), select LSP Ping and click . In the Advanced Parameter dialog box that is displayed, set LSP 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 tunnel, 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 an LSP traceroute test to locate the fault.

  5. Optional: Perform an LSP traceroute test on the affected tunnel to locate the fault.
    1. Click the Configuration tab.
    2. On the Diagnosis Option pane (located in the lower left area), select LSP Traceroute and click . In the Advanced Parameter dialog box that is displayed, set LSP traceroute 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 tunnel by clicking Details in the Check Result pane.

Follow-up Procedure

If the tunnel test fails, see Handling MPLS Tunnel Faults for troubleshooting measures.

Testing Tunnel Performance Using DM in MPLS-TP Tunnel OAM

The LM and DM functions in MPLS-TP tunnel OAM allow you to test tunnel performance online with no need for any test instruments. The LM and DM functions do no affect services.

Prerequisites

  • MPLS tunnels have been created and deployed. For details on how to create MPLS tunnels, see Configuring an MPLS Tunnel.
    NOTE:

    Before managing an MPLS tunnel that is created on a per-NE basis, you need to search for the MPLS tunnel. For details on how to search for MPLS tunnels, see Searching for MPLS Tunnels.

  • MPLS-TP OAM has been configured and enabled on the service source and sink nodes. For details, see Configuring MEPs of MPLS-TP Tunnel OAM.
  • The OAM protocol on the service source and sink nodes has been switched to Y.1731. For details, see Switching the Tunnel OAM Standard.
    NOTE:

    The Y.1731 OAM mode complies with ITU-T G.8113.1.

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