Huawei OptiX OSN 550, Configuration Manual, Page: 198 / 470

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.
4.5.3 Configuration Process
This topic describes the process of configuring Ethernet private line services for Ethernet
switching boards.
4.5.4 Configuration Process (End-to-End Mode)
During the configuration of EPL services on Ethernet switching boards, you need to configure
Ethernet private line services. This topic describes the process of configuring EPL services for
Ethernet switching boards in end-to-end mode.
4.5.1 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 4-24 , the service requirements are as follows:
l 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.
l 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.
l The services of user A must be isolated from the services of user B.
l 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.
