Configuring PORT-Shared EVPL (VLAN) Services

Configuring PORT-Shared EVPL (VLAN) Services

The PORT-shared EVPL (VLAN) service is applicable when the services of multiple users received from the same external port on the Ethernet board at a station are transmitted on different VCTRUNKs to another station or to another external port of the station.

Networking Diagram

The services of multiple users received from the same external port on an Ethernet board of a station are transmitted to different stations on different VCTRUNKs.

Service Requirement

In the network as shown in Figure 2-71, the service requirements are as follows:

  • The headquarters C1 of user C is located at NE1. Two branches (C2 and C3) of user C are located at NE2 and NE4. The services between C1 and C2 are transmitted in the VLAN of which the VLAN ID is 100. The services between C1 and C3 are transmitted in the VLAN of which the VLAN ID is 200.
  • The services of C2 are isolated from the services of C3. The services of C2 and C3 require a 20 Mbit/s bandwidth respectively.
  • The Ethernet equipment of C1, C2, and C3 provides 100 Mbit/s Ethernet electrical interfaces that work in auto-negotiation mode. The Ethernet equipment of C1 supports VLANs, but the Ethernet equipment of C2 and C3 does not support VLANs.
    • The VLAN ID used by the Ethernet services between C1 and C2 is 100.
    • The VLAN ID used by the Ethernet services between C1 and C3 is 200.

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

In this example, NE1 is configured with an EFS8 board. VLAN IDs are used to isolate the data of different users received from the same port. NE2 and NE4 are each configured with an EGT1 board. The EPL services are configured to implement service transparent transmission from NE2 and NE4 to NE1.

In this example, NE1 is configured with an EFS8 board. NE2 and NE4 are each configured with an EGT1 board.

Signal Flow and Timeslot Allocation

Ethernet services wherein different VLAN IDs are used to isolate the data of different users are received from the same external port of NE1, encapsulated through an internal port, and transparently transmitted on the SDH network. In this way, the node communicates with a remote node.

Figure 2-72 shows the signal flow of the PORT-shared EVPL (VLAN) services and the timeslot allocation to the PORT-shared EVPL (VLAN) 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.

  • The EVPL service from C1 to C2:
    • Occupies the first to tenth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-10) on the SDH link from NE1 to NE2.
    • Is added and dropped by using the first to tenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-10) on the EFS8 board of NE1 and the first to tenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-10) on the EGT1 board of NE2.
  • The EVPL service from C1 to C3:
    • Occupies the first to tenth VC-12 timeslots of the first VC-4 (VC4-1:VC12:1-10) on the SDH link from NE1 to NE4.
    • Is added and dropped by the using the eleventh to twentieth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:11-20) on the EFS8 board of NE1 and the first to tenth VC-12 timeslots of the fourth VC-4 (VC4-4:VC12:1-10) on the EGT1 board of NE4.
