Configuring Ethernet Services
About This Chapter This chapter describes the process of configuring Ethernet private line (EPL) and Ethernet private local area network (EPLn) services on the T2000, and related engineering requirements and engineering information as well. The configuration of Ethernet virtual private line (EVPL) and Ethernet virtual private local area network (EVPLn) will be described with resilient packet ring (RPR) in Chapter 4. Through this example, you can learn how to configure EPL and other similar services. The following table is a mapping table which associates the Ethernet services to the Ethernet boards of the OptiX OSN 3500/2500/1500.

In this chapter, the OptiX OSN 3500 product is taken as an example. For the OptiX OSN 2500 and the OptiX OSN 1500A/B, service configuration is performed in the same way. The only difference is that the boards of the OptiX OSN 2500 and the OptiX OSN 1500A/B are inserted in different slots.
The following table lists the contents of this chapter.

3.1 Configuring the Point-to-Point EPL Service 3.1.1 Engineering Requirements The two companies A and B in NE1 need to transmit data services to NE5 through multi-service transport platform (MSTP) equipment. The services of A and B are required to be completely isolated. Both A and B provide 100 Mbit/s Ethernet electrical interfaces. A requires 10 Mbit/s bandwidth, B requires 40 Mbit/s bandwidth, and their interconnected equipment does not support VLAN, as shown in Table 3-2. Table 3-2 Service requirement of each station User

3.2 Configuring the PORT Shared EPL Service 3.2.1 Engineering Requirements The headquarters of company C is located in NE1, with two branches (M&S Department and Technical Support Department) located in NE5. The headquarters needs to communicate with two branches. The service of the two branches is required to be isolated completely, each occupying 10 Mbit/s bandwidth. The Ethernet switch of company C provides 100 Mbit/s Ethernet electrical interfaces. The Ethernet switch of headquarters supports virtual local area network (VLAN), but the interconnected equipment of the two branches does not.

They need to communicate with each other. E and E' are users of large corporations and located in NE2 and NE3 respectively. They also need to communicate with each other. Services of communities and that of corporations are isolated completely. Because the traffic peak of community services is at night and that of corporation services is in daytime, they can share a 300 Mbit/s bandwidth. Their Ethernet equipment provides GE optical interfaces but does not support VLAN.
