Configuration Example: E-Line Services Carried by PWs(Based on VLANs)

This topic uses an example to describe how to plan the engineering information and how to configure the E-Line services carried by PWs for each NE according to the networking diagram.

Networking Diagram

The networking diagram shows the requirements for the E-Line services carried by PWs (based on VLANs).

On the network shown in Figure 3-10, the service requirements of User A and User B are as follows:

  • User A1 and User B1 are connected to NE1 through the 4-EM6F-3 and 4-EM6F-4 ports respectively.
  • User A2 and User B2 are connected to NE4 through the 4-EM6F-3 and 4-EM6F-4 ports respectively.
  • The service between User A1 and User A2 is the common Internet access service of which the CIR is 10 Mbit/s and the PIR is 30 Mbit/s.
  • The service between User B1 and User B2 is the data service of which the CIR is 30 Mbit/s and the PIR is 50 Mbit/s.
  • The services of User A and User B each are carried on one PW link.
  • The two PW links that carry the services of User A and User B share the bandwidth of one tunnel.
  • The service between User A and User B is configured with MPLS tunnel APS.
    • Working path: NE1-NE2-NE4
    • Protection path: NE1-NE3-NE4

NOTE:
  • This topic considers the OptiX OSN 550 as an example to describe the board layout. In the case of other products, the configuration method is the same, except for the slots. For the slot information, see the Hardware Description of the relevant product.
  • On a live data network, an Ethernet service is added to the source NE, passed through the transit NEs, and dropped from the sink NE. Follow instructions in Configuring Transit NEs for Ethernet Services Carried by PWs to configure transit NEs for the Ethernet services carried by PWs.

Service Planning

The engineering information for configuring the E-Line services carried by PWs contains the engineering information for configuring the tunnel carrying the PWs, the engineering information for configuring the PWs, and the engineering information for configuring the UNI-NNI E-Line services carried by the PWs.

The PWs that carry the E-Line services are carried by a tunnel. Hence, you need to plan the tunnel during the service planning. Therefore, planning the E-Line services carried by PWs involves the following:

Configuration Process (in End-to-End Mode)

Before configuring E-Line services carried by PWs, you need to configure the tunnels that carry the PWs.

Prerequisites

  • You must be familiar with the networking requirements and service planning information of the UNI-NNI E-Line services carried by the PWs.
  • You are an NM user with Administrators rights or higher.
  • If the E-Line services carried by PWs need to occupy the UNI ports exclusively, disable the DCN function of the UNI ports. For the method of disabling the DCN function of a port, see Configuring the DCN Function for a Port.

Procedure

  1. Follow the instructions in Configuring LSR ID and Configuring the NNIs for Ethernet Services Carried by Static MPLS Tunnels and configure LSR IDs for NEs and NNIs for services carried by MPLS tunnels.

Relevant Task

See Verifying the Correctness of E-Line Service Configuration to check whether the E-Line services carried by PWs are configured correctly.

Configuration Process (Configuration on a Per-NE Basis)

Before configuring E-Line services carried by PWs, configure the tunnels that carry the PWs, MPLS tunnel OAM, and MPLS tunnel APS according to service planning.

Prerequisites

  • You must be familiar with the networking requirements and service planning information of the UNI-NNI E-Line services carried by the PWs.
  • You are an NM user with Administrators rights or higher.
  • If a port needs to be occupied exclusively, you need to disable the DCN function of the port. For details, see Configuring the DCN Function for a Port.

Procedure

  1. On NE1, NE2, NE3 and NE4, configure the tunnels that carry the PWs. For the configuration procedures, see Configuring an MPLS Tunnel.

Relevant Task

See Verifying the Correctness of E-Line Service Configuration to check whether the E-Line services carried by PWs are configured correctly.

Verifying the Correctness of E-Line Service Configuration

The LB function provided by ETH OAM is used to test whether Ethernet services are available.

Prerequisites

  • You are an NM user with Administrators rights or higher.
  • Ethernet services have been configured. For details on how to configure Ethernet services, see Configuring ETH PWE3 Services in the Configuration Guide (Packet Transport Domain).
Application Scenario

The LB function in ETH OAM can be used to test the following services (PW-carried E-Line services, for example):

  • Native ETH-carried E-Line and E-LAN services
  • PW-carried E-Line (based on VLAN) and E-LAN services
Precautions

For details on the feature dependencies and limitationshow to configure ETH OAM services, Please see Feature Dependencies and Limitations in the Feature Description.

Tools, Equipment, and Materials

U2000

Background Information

For details about the boards that support the ETH OAM function, see Availability of the ETH OAM function in the Feature Description.

Huawei's Ethernet service processing boards can achieve ETH OAM in compliance with IEEE 802.1ag and IEEE 802.3ah. IEEE 802.1ag define the OAM standards for Ethernet services; IEEE 802.3ah defines the OAM standards for Ethernet ports. As shown in Figure 3-11, the two recommendations are applied to provide a complete ETH OAM solution.

NOTE:

The OptiX OSN is usually applied to the access layer of networks.

  • Ethernet service OAM achieves end-to-end maintenance for Ethernet links. It functions based on "maintenance domains" which segment the trail that an Ethernet service travels along.
  • Ethernet port OAM achieves point-to-point maintenance for Ethernet links. It functions based on the two directly-connected devices of Ethernet in the First Mile (EFM). Ethernet port OAM can be performed by means of auto-discovery, link performance monitoring, fault detection, remote loopback, and self-loop detection.

Procedure

  1. Optional: Convert the Ethernet services that are created in per-NE mode to end-to-end PWE3 services.
    1. Choose Service > Search for IP Service from the main menu.
    2. In the dialog box that is displayed, set the auto-discovery policies.
    3. Click Start.
    4. After the auto-discovery is finished, click Close.
  2. Choose Service > PWE3 Service > Manage PWE3 Service from the Main Menu.
  3. In the dialog box that is displayed, set the filter conditions. For example, set Protocol Type to PW APS. Then click Filter.
  4. Right-click the required PW-carried E-Line service and choose Ethernet OAM > ETH OAM Test from the shortcut menu.
  5. Set the Measurement Type as LB in the dialog box that is displayed.
  6. Click Run.
  7. After the test is finished, click the LB Statistic Information tab and check the test results.



    NOTE:

    The service under test has normal connectivity if the number of transmitted packets equals the number of received packets.
