Chapter 2 EVPL Service Configuration using Station by Station Method (PORT-Shared)
2.2 Service Requirements
The headquarters of company H; H1 is located to NE A, while there are two branches which are H2 and H3 are located to NE B and NE D each. Both branches needed to have Ethernet communication with the headquarters and a bandwidth of 2Mbits/s is needed each.
2.3 Parameters Description
The network planning is shown below:
1. EVPL service between company H headquarters, H1 and branch H2;
2. EVPL service between company H headquarters, H1 and branch H3;
EVPL service between company H headquarters, H1 and branch H2:
− Use VC-12 timeslot number 4 of VC4 number 1 for SDH link between NE A and NE B（VC4-1:VC12:4）.
− Use VC-12 timeslot number 4 of VC4 number 4（VC4-4:VC12:4） of N2EFS4 board for NE A and VC-12 timeslot number 1 of VC4 number 4 （VC4-4:VC12:1）of N2EFS4 board for NE B to add drop services.

2.5 Test Service Configuration
When all the configuration has been completed, the configurations have to be tested to make sure it works. First, you must make sure the Tag Attributes of the external port of NE A is configured as “Access” (PCs cannot ping each other when the ports are in Tag Aware mode as PCs do not have VLAN IDs.
Test Ethernet Service between NE A and NE B:
Two PCs are needed to test the connectivity, connect two PCs to port 2 of Ethernet board in NE A and port 1 of Ethernet board in NE B each.
PCs with IP addresses of 188.20.7.100 and 188.20.7.101 were used for the
“ping” test in this case. The results below show the EPL service is working normally.
