3.3 Configuration Example (PORT-Shared EVPL Services)
This topic uses an example to describe how to plan the service parameters and complete the entire process of configuring the parameters of each NE according to the PORT-shared EVPL service requirements.
3.3.1 Networking Diagram
The networking diagram forms the foundation of service planning. In the following example, the networking diagram shows the NE networking mode and service requirements.
3.3.2 Service Planning
According to the service requirements and the equipment specifications that are shown in the networking diagram, the network planning department can plan all the parameters that are required for configuring the new Ethernet services of the NEs.
3.3.3 Configuring NE1
You can configure the PORT-shared Ethernet private line services of NE1 based on the parameters of the service planning, by using the NMS.
3.3.4 Configuring NE2 and NE3
You can configure the Ethernet services of NE2 and NE3 based on the parameters of the service planning, by using the NMS.
3.3.1 Networking Diagram
The networking diagram forms the foundation of service planning. In the following example, the networking diagram shows the NE networking mode and service requirements.
As shown in Figure 3-5, NE1, NE2, and NE3 are the OptiX RTN 600 NEs that are configured with the IDU 620. 16xE1 services exist between NE1, NE2, and NE3. The new service requirements are as follows:
l The headquarters C1 of User C are located at NE1 and the two branches of User C (C2 and
C3) are located at NE2 and NE3. The services between C1 and C2 are transmitted in the VLAN of which the VLAN ID ranges from 100 to 110. The services between C1 and C3 are transmitted in the VLAN of which the VLAN ID ranges from 200 to 210.
l The services of C2 are isolated from the services of C3. The services of C2 and C3 require
a 20 Mbit/s bandwidth respectively.
l The Ethernet equipment of C1, C2, and C3 provide 100 Mbit/s Ethernet electrical ports of

3.3.2 Service Planning
According to the service requirements and the equipment specifications that are shown in the networking diagram, the network planning department can plan all the parameters that are required for configuring the new Ethernet services of the NEs.
In the following example, NE1 needs to use Ethernet switching boards to create PORT-shared EVPL services. NE2 and NE3 can use Ethernet transparent transmission boards to create PORT- shared EVPL services.
