Configuring EVPLAN Services (IEEE 802.1q Bridge)

Configuring EVPLAN Services (IEEE 802.1q Bridge)

The EVPLAN service (IEEE 802.1q bridge) provides an LAN solution for multipoint-to-multipoint convergence. This service applies in cases where user-side data communication equipment connected to the transmission network does not support VLANs or where the VLAN planning is open to the network operator.

Networking Diagram

The convergence node needs to exchange Ethernet services with two access nodes at Layer 2. LAN services of the two users (H and G) need to be isolated.

Service Requirement

In the network shown in Figure 2-77, the service requirements are as follows:

  • Three branches (G1, G2, and G3) of user G are located at NE1, NE2, and NE4 respectively. The branches need to form a LAN and share a 10 Mbit/s bandwidth. G2 and G3 do not need to communicate with each other.
  • Three branches (H1, H2, and H3) of user H are located at NE1, NE2, and NE4 respectively. The branches need form a LAN and share a 20 Mbit/s bandwidth. H2 and H3 need to communicate with each other.
  • The service of user G needs to be isolated from the service of user H.
  • The Ethernet equipment of user G and user H provides 100 Mbit/s Ethernet electrical interfaces that work in auto-negotiation mode and do not support VLANs.

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

For the EVPLAN (IEEE 802.1q bridge) services supported by Ethernet switching boards, refer to Table 2-152.

In this example, the convergence node NE1 is configured with an EFS8 board that supports the IEEE 802.1q bridge to implement EVPLAN services in which user data is isolated.

The access nodes NE2 and NE4 each are configured with two Ethernet transparent transmission boards respectively, which occupy logical slots 3 and 4. The EPL services are configured to implement transparent transmission from NE2 and NE4 to NE1.

Signal Flow and Timeslot Allocation

The Ethernet services of the convergence node are received from an external port and tagged with the corresponding VLAN IDs. After the services are forwarded to an internal port through Layer 2 switching, the VLAN IDs are stripped and then the services are transparently transmitted in the SDH network. In this way, the node communicates with a remote node.

Figure 2-78 shows the signal flow of the EVPLAN services (IEEE 802.1q bridge) and the timeslot allocation to the EVPLAN services (IEEE 802.1q bridge).

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.

    6. Configure the cross-connections from the Ethernet service to the SDH link for user G2, user G3, user H2, and user H3.

      • In the NE Explorer, select NE1, and then choose Configuration > SDH/PDH Service Configuration from the Function Tree.
      • Click Create on the lower-right pane to display the Create SDH/PDH Service dialog box. Set the parameters as follows.
        User Parameter Value in This Example Description
        User G1←→user G2 Level VC12 The timeslot bound with the service between user G1 and user G2 is at the VC-12 level. The service level must be consistent with the level of the path bound with the VCTRUNK.
        Direction Bidirectional The service between user G1 and user G2 is a Bidirectional service.
        Source Slot 4-EFS8-1(SDH-1) When you create a bidirectional SDH service from an Ethernet board to a line board, it is recommended that you set the slot of the Ethernet board as the source slot.
        Source VC4 VC4-4 The value range of Source VC4 is consistent with the value range of Available Resources, which is set for the paths bound with VCTRUNK1. In the case of VCTRUNK1, Available Resources is set to VC4-4.
        Source Timeslot Range(e.g.1,3-6) 1-5 The value range of the source timeslots is consistent with the value range of Available Timeslot, which is set for the paths bound with VCTRUNK1. In the case of VCTRUNK1, the value of Available Timeslot is from VC12-1 to VC12-5.
        Sink Slot 6-SL4D-1(SDH-1) When you create a bidirectional SDH service from an Ethernet board to a line board, it is recommended that you set the slot of the line board as the sink slot.

The number of source timeslots must be, however, the same as the number of sink timeslots. For example, if the source timeslots are five VC-12s, the sink timeslots must be five VC-12s.

  2. Configure the EPL services on NE2 and NE4.

    NOTE:
    The Ethernet services of NE2 and NE4 are point-to-point transparent transmission services. See Configuring EPL Services on an Ethernet Transparent Transmission Board to set the parameters.

  3. Check whether the services are configured correctly.
  4. Enable the performance monitoring function of the NEs. For details, see Setting Network-Wide Performance Monitoring.
  5. Back up the configuration data of the NEs. For details, see Backing Up the NE Data to the System Control Board.
Relevant Task

If the services are configured incorrectly and thus need to be deleted, see Deleting EVPLAN Services.
