Chapter 4 EPLAN Service Configuration using Station by Station Method
4.1 Laboratory Network Topology Introduction
The network topology diagram is as follows, the network elements (NEs) consist of 5 OptiX OSN 3500. The basic topology is form from a four NEs two-fiber bidirectional multiplex section protection ring with a non-protection chain. Pair slot of slot #7 and #12 is used in each NE in the ring network; slot
#7 is connected to slot #12 in the next NE. A non-protection chain is form from NE A slot #6 connected to NE E slot #12. The GNE and board slot number can be changed according to the actual situation during the configuration. One N2EFS4 board is configured in every NE and the actual slot number for each board is shown as follows. The slot number can be flexibly adjusted according to actual configuration situation.

4.2 Service Requirement
The headquarters of company H, H1 is located to NE A, while company H’s branches H2 and H3 are located to NE B and NE D respectively.
Headquarters, H1 needs Ethernet service communication with branch H2 and H3 which requires a 6Mbits/s bandwidth for communication with each branch.
4.3 Parameters Description
The convergence node needs to exchange Ethernet services with two access nodes at Layer 2. The Ethernet services are transmitted transparently through the SDH network to interact with the remote node.
Use VC12 timeslot number 1 to 3 of VC4 number 1 for SDH link between NE A and NE B（VC4-1:VC12:1-3）, and between NE A and NE D
（VC4-1:VC12:1-3）.
For Ethernet LAN service between NE A and NE D, use VC-12 timeslot number 1 to 3 of VC4 number 4（VC4-4:VC12:1-3）of N2EFS4 board of NE A and NE D to add and drop service.
For Ethernet LAN service between NE A and NE B, use VC-12 timeslot number 4 to 6 of VC4 number 4 （VC4-4:VC12:4-6）of N2EFS4 board of NE A and use VC-12 timeslot number 1 to 3 of VC4 number 4 VC4-4:VC12:1-3）of N2EFS4 board of NE B to add and drop service.

76 2、At the Ethernet LAN service panel, click “New”, (When the bridge adopts the SVL learning mode, all the VLANs share the same MAC address table. That is, the bridge learns and forwards the packets according to the MAC address of the user packets only. The information in the VLAN tags of the user packets, however, is not considered in the learning and forwarding process.) Take note that the VB name must be set, the VB name “AB_LAN” was set as shown below. Select the correct parameters and click “Configure Mount”.
3、AT the panel, click “Configure Mount” button and select PORT1, VCTRUNK1 and VCTRUNK by clicking the “>>” button. Click “OK” when finish.
