Configuring EPL Services on an Ethernet Switching Board

Configuring EPL Services on an Ethernet Switching Board

EPL services provide the point-to-point Ethernet transparent transmission solution with the bandwidth exclusively occupied. EPL services are applicable when the communication equipment that is used to access the client-side data in the transmission network does not support VLANs or when the VLAN planning must be kept secret to the network operator.

Networking Diagram

The completely isolated data services of two users at a station must be transported to another station.

Service Requirement

In the network as shown in Figure 2-69, the service requirements are as follows:

  • The two branches of user A that are located at NE1 and NE3 need to communicate with each other over Ethernet. A 10 Mbit/s bandwidth is required.
  • The two branches of user B that are located at NE1 and NE3 need to communicate with each other over Ethernet. A 20 Mbit/s bandwidth is required.
  • The services of user A must be isolated from the services of user B.
  • The Ethernet equipment of user A and user B provides 100 Mbit/s Ethernet ports of which the working mode is auto-negotiation, and does not support VLANs.
Figure 2-69  Networking diagram of the EPL services

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.

Board Configuration Information

Ethernet transparent transmission boards or Ethernet switching boards can be used to configure EPL services. The Ethernet switching processing board is displayed as the EFS8 on the U2000, which occupies logical slot 4.

In this example, NE1 and NE3 each are configured with one EFS8 board, which is an Ethernet switching board.

Signal Flow and Timeslot Allocation

Ethernet services are received from an external port, encapsulated through an internal port, and mapped to the SDH network for transparent transmission. In this way, the node communicates with a remote node.

Figure 2-70 shows the signal flow and timeslot allocation of the EPL services.

For the method of calculating the bandwidth of the Ethernet services carried by a VCTRUNK, see Ethernet Service Bandwidths Carried by VCTRUNKs of Ethernet Boards.

Figure 2-70  Signal flow and timeslot allocation (Ethernet switching board)

  • The EPL services of user A:
    • Occupy the first to fifth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-5) on the SDH link between NE1 and NE3 and pass through NE2.
    • Are added and dropped by using the first to fifth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-5) on the EFS8 board of NE1 and the first to fifth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-5) on the EFS8 board of NE3.
  • The EPL services of user B:
    • Occupy the sixth to fifteenth VC-12 timeslots of the first VC-4 (VC4-1:VC12:6-15) on the SDH link between NE1 and NE3 and pass through NE2.
    • Are added and dropped by using the sixth to fifteenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:6-15) on the EFS8 board of NE1 and the sixth to fifteenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:6-15) on the EFS8 board of NE3.

Configuration Process (Configuration on a Per-NE Basis)

This topic describes the process of configuring Ethernet private line services for Ethernet switching boards.

Prerequisites

You must be familiar with Flow of Configuring EPL Services.

Background Information

If the Ethernet switching boards in the actual application scenarios are different from the boards in this example, you need to learn about the requirements for configuring specific boards.

Procedure

  1. Configure the EPL services for users A1 and B1 on NE1.
    1. Set the attributes of the external ports (PORT1 and PORT2 on the EFS8 board) used by the services of users A1 and B1.

      • In the NE Explorer, select the EFS8 and then choose Configuration > Ethernet Interface Management > Ethernet Interface from the Function Tree.
      • Select External Port.
      • Click the Basic Attributes tab. After setting the parameters, click Apply.
        Parameter Value in This Example Description

        Enabled/Disabled

        PORT1: Enabled

        PORT2: Enabled

        PORT1 is used by the service of user A1. PORT2 is used by the service of user B1. In this example, Enabled/Disabled is set to Enabled for PORT1 and PORT2.

        Working Mode

        PORT1: Auto-Negotiation

        PORT2: Auto-Negotiation

        In this example, the Ethernet service access equipment of user A1 and user B1 supports the auto-negotiation mode. Hence, Working Mode is set to Auto-Negotiation for PORT1 and PORT2.

        Maximum Frame Length

        PORT1: 1522

        PORT2: 1522

        Generally, this parameter adopts the default value 1522.

        MAC Loopback

        PORT1: Non-Loopback

        PORT2: Non-Loopback

        The MAC loopback setting is used for fault diagnosis. In this example, MAC Loopback is set to Non-Loopback.

        PHY Loopback

        PORT1: Non-Loopback

        PORT2: Non-Loopback

        The PHY loopback setting is used for fault diagnosis. In this example, PHY Loopback is set to Non-Loopback.
      • Click the Flow Control tab. The parameters in the Flow Control tab page adopt the default values.
      • Click the TAG Attributes tab. After setting the parameters, click Apply.
        Parameter Value in This Example Description
        TAG

        PORT1: Access

        PORT2: Access

        The access equipment of user A1 and user B1 does not support the VLAN. Hence, the access equipment transmits only the packet without the VLAN tag. In this example, it is recommended that you set the TAG flags at PORT1 and PORT2 to Access.

        Default VLAN ID

        PORT1: 1

        PORT2: 1

        The services of user A1 and user B1 exclusively occupy the PORTs and VCTRUNKs. Hence, the VLAN ID is not required for isolating the services. In this example, Default VLAN ID adopts the default value.
        VLAN Priority

        PORT1: 0

        PORT2: 0

        Both the VLAN ID and VLAN priority are unnecessary for users A1 and B1. In this example, VLAN Priority adopts the default value.
        Entry Detection

        PORT1: Disabled

        PORT2: Disabled

        The services of user A1 and user B1 are EPL transparent transmission services. Hence, you need not enable the entry detection function to check the VLAN tags of the packets. In this example, Entry Detection need to be set to Disabled. When Entry Detection is set to Disabled, the parameters of TAG, Default VLAN ID, and VLAN Priority are invalid.

      • Click the Advanced Attributes tab. The parameters in the Advanced Attributes tab page adopt the default values.

    2. Set the attributes of the internal ports (VCTRUNK1 and VCTRUNK2 of the EFS8 board) used by the services of user A1 and user B1.

      • Select Internal Port.
      • Click the TAG Attributes tab. After setting the parameters, click Apply.
        Parameter Value in This Example Description
        Entry Detection

        VCTRUNK1: Disabled

        VCTRUNK2: Disabled

        The services of user A1 and user B1 are EPL transparent transmission services. Hence, you need not enable the entry detection function to check the VLAN tags of the packets. In this example, Entry Detection need to be set to Disabled. When Entry Detection is set to Disabled, the parameters of TAG, Default VLAN ID, and VLAN Priority are invalid.

      • Click the Network Attributes tab. After setting the parameters, click Apply.
        Parameter Value in This Example Description
        Port Attributes

        VCTRUNK1: UNI

        VCTRUNK1: UNI

        UNI indicates the user-network interface, namely, the interface of the service provider located near the user side. The UNI interface processes the tag attribute of IEEE 802.1Q-compliant packets. That is, the UNI interface processes and identifies the VLAN information of the accessed user packets, according to the supported tag flag, namely, Tag Aware, Access, and Hybrid.
      • Click the Encapsulation/Mapping tab. After setting the parameters, click Apply.
        Parameter Value in This Example Description
        Mapping Protocol

        VCTRUNK1: GFP

        VCTRUNK2: GFP

        In this example, the EFS8 board is used. This parameter adopts the default value GFP. Mapping Protocol of the VCTRUNKs on the Ethernet boards of the interconnected equipment at both ends must be set to the same value.
        Scramble

        VCTRUNK1: Scrambling mode [X43+1]

        VCTRUNK2: Scrambling mode [X43+1]

        In this example, this parameter adopts the default value Scrambling mode [X43+1]. Scramble of the VCTRUNKs on the Ethernet boards of the interconnected equipment at both ends must be set to the same value.
        Check Field Length

        VCTRUNK1: FCS32

        VCTRUNK2: FCS32

        In this example, this parameter adopts the default value FCS32. Check Field Length of the VCTRUNKs on the Ethernet boards of the interconnected equipment at both ends must be set to the same value.
        FCS Calculated Bit Sequence

        VCTRUNK1: Big endian

        VCTRUNK2: Big endian

        When Mapping Protocol is set to GFP, FCS Calculated Bit Sequence is set to Big endian. FCS Calculated Bit Sequence of the VCTRUNKs on the Ethernet boards of the interconnected equipment at both ends must be set to the same value.
        Set Inverse Value for CRC

        VCTRUNK1: -

        VCTRUNK2: -

        When Mapping Protocol is set to GFP, this parameter is valid and adopts the default value -. Set Inverse Value for CRC of the VCTRUNKs on the Ethernet boards of the interconnected equipment at both ends must be set to the same value.
