4 Configuring Ethernet Services
Step 2 Configure the EPL services on NE2 and NE4.
NOTE
Step 3 Check whether the services are configured correctly. For the operation procedures, see Testing
Ethernet Service Channels.
l Before testing the service connectivity between F1 and F2, set TAG to Access and set Default
VLAN ID to 1 for PORT1 and VCTRUNK1, which receive the services of F1 and F2
respectively, on the EFS8 board.
l Before testing the service connectivity between F1 and F3, set TAG to Access and Default
VLAN ID to 1 for PORT1 and VCTRUNK2, which receive the services of F1 and F3
respectively, on the EFS8 board.
NOTE
Step 4 Enable the performance monitoring function of the NEs. For details, see Setting Performance
Monitoring Parameters of an NE.
Step 5 Back up the configuration data of the NEs. For details, see Backing Up the NE Database to the
SCB Board.

4.9 Configuring EVPLAN Services (IEEE 802.1q Bridge)

The EVPLAN service (IEEE 802.1q bridge) provides an LAN solution for multipoint-to-
multipoint convergence. This service applies in cases where user-side data communication
equipment connected to the transmission network does not support VLANs or where the VLAN
planning is open to the network operator.

4.9.1 Networking Diagram

The convergence node needs to exchange Ethernet services with two access nodes at Layer 2.
LAN services of the two users (H and G) need to be isolated.

4.9.2 Signal Flow and Timeslot Allocation

The Ethernet services of the convergence node are received from an external port and tagged
with the corresponding VLAN IDs. After the services are forwarded to an internal port through
Layer 2 switching, the VLAN IDs are stripped and then the services are transparently transmitted
in the SDH network. In this way, the node communicates with a remote node.
4.9.3 Configuration Process
At the convergence node NE1, you need to create An EVPLAN service (IEEE 802.1q bridge)
and a VLAN filtering table need to be created for the convergence node NE1. The access nodes
NE2 and NE4 need to be configured with EPL transparent transmission services only.

The Ethernet services of NE2 and NE4 are point-to-point transparent transmission EPL services. See
Configuring EPL Services on an Ethernet Transparent Transmission Board
After the test, change the modified parameter values to the values specified in the service configuration.
