Configuring MPLS-TP Tunnel OAM

Configuring MPLS-TP Tunnel OAM

This section describes how to configure MPLS-TP tunnel OAM.

Configuring MPLS-TP Tunnel OAM

This section describes how to smoothly switch the tunnel OAM standard from ITU-T Y.1711 with which the centralized MPLS tunnel OAM complies to ITU-T G.8113.1 with which MPLS-TP tunnel OAM complies.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Tunnels have been created.
    NOTE:

    Before managing a tunnel that is created on a per-NE basis, you need to search for the tunnel. For details on how to search for a tunnel, see "Searching for MPLS Tunnels" in the Configuration Guide (Packet Transport Domain).

NOTE:

The Y.1731 mode indicates the ITU-T G.8113.1 compliant OAM mode.

Procedure

  • Switching the tunnel OAM standard on a per-NE basis.
    1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.
    2. In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management.
    3. Click the Static Tunnel tab, and select one or more tunnels.

      NOTE:

      The OAM standard can be switched only for ingress nodes and egress nodes.

    4. Right-click and choose Switch to Y.1731 from the shortcut menu. A dialog box is displayed, indicating the operation result.

    5. Click Close.
  • Switching the tunnel OAM standard in end-to-end mode.
    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. Select one or more tunnels.
    4. Right-click and choose MPLS OAM > Switch to Y.1731. A dialog box is displayed, indicating the operation result.

    5. Click Close.

Configuring MEPs of MPLS-TP Tunnel OAM

This section describes how to configure MEPs of MPLS-TP tunnel OAM. MEPs are end points of MEGs. MEPs can initiate and terminate OAM packets, which helps to implement fault management and performance monitoring.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Global OAM parameters have been configured.
  • Tunnels have been created. The tunnel OAM standard has been switched to ITU-T G.8113.1 with which MPLS-TP tunnel OAM complies.

Procedure

  1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.
  2. In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management.
  3. On the MPLS-TP OAM tab page, click the MEP tab.
  4. Set MPLS-TP tunnel OAM parameters for MEPs. Set OAM Status to Enabled.

    NOTE:

    If you want to perform an LCK test on a tunnel, you need to set Lock Status to Lock.

  5. Click Apply. In the Warning dialog box, choose I have read the message and fully understood the operation impacts on services., then click Yes.
  6. In the Result dialog box indicating that the operation is successful, click Close.

Configuring MIPs of MPLS-TP Tunnel OAM

This section describes how to configure MIPs of MPLS-TP tunnel OAM. MIPs are intermediate points of MEGs. MIPs can forward OAM packets and respond to some OAM packets, but cannot initiate OAM packets. If MEG ID Type is not IP Based and an LT test needs to be performed, you need to configure MIPs on transit nodes.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Global OAM parameters have been configured.
  • Tunnels have been configured on transit nodes. The tunnel OAM standard has been switched to ITU-T G.8113.1 with which MPLS-TP tunnel OAM complies.

Procedure

  1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.
  2. In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management.
  3. On the MPLS-TP OAM tab page, click the MIP tab.
  4. Click New. In the Create Tunnel MIP dialog box, set MPLS-TP tunnel OAM parameters for an MIP.
    1. Select Tunnel and click . In the Select Tunnel dialog box, select the corresponding tunnel and click OK.
    2. Set MEG ID Type, MEG ID, and MIP ID.

  5. Click Apply. A dialog box is displayed, indicating the operation result.
  6. Click Close.

Starting CC of MPLS-TP Tunnel OAM

This section describes how to start CC of MPLS-TP tunnel OAM. CC is used to check the connectivity between two MEPs in an MEG.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Tunnels have been created, and MPLS-TP OAM has been configured.

Procedure

  1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.
  2. In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management.
  3. On the MPLS-TP OAM tab page, click the MEP tab.
  4. Select one or more tunnels and set OAM Status to Enabled.

  5. Choose OAM Operation > Start CC. A dialog box is displayed, indicating the operation result.

  6. Click Close.

Enabling AIS of MPLS-TP Tunnel OAM

If AIS of MPLS-TP tunnel OAM is enabled, a fault on a tunnel triggers AIS packet transmission at the PW layer and an AIS alarm is generated.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Tunnels have been created, and MPLS-TP OAM has been configured.

Procedure

  1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.
  2. In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management.
  3. On the MPLS-TP OAM tab page, click the MEP tab.
  4. Select one or more tunnels and set AIS Status to Enabled.

  5. Click Apply. In the Warning dialog box, choose I have read the message and fully understood the operation impacts on services., then click Yes.
  6. In the Result dialog box indicating that the operation is successful, click Close.

Performing LB of MPLS-TP Tunnel OAM

Procedure

  1. On the Main Topology, right-click the required NE and choose NE Explorer from the shortcut menu.

    An LB test can be started only when OAM is enabled.

  5. Choose OAM Operation > Start LB. The LB Test dialog box is displayed.

  6. Set LB test parameters.

  7. Click Start Test. View the test result in Test Result.

    NOTE:
    • Total of TX: number of packets sent each time
    • Total of RX: number of packets received each time
    • Total Rate (%): percentage of the received packets in total packets transmitted
    • Min Delay (us): minimum transmission time of a single packet
    • Max Delay (us): maximum transmission time of a single packet
    • Avg Delay (us): average transmission time of a single packet
