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.
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.

4.10 Configuring EVPLAN Services (IEEE 802.1ad Bridge)

The QinQ technology provides a cheap and easy solution for Layer 2 virtual private networks
(VPNs). The IEEE 802.1ad bridge uses the QinQ technology to provide the VPN solution, thus
facilitating the identifying, differentiating and grooming EVPLAN services.

4.10.1 Networking Diagram

A network operator requires that the voice over IP (VoIP) and high speed Internet (HSI) services
sent to the transmission network be uniformly labeled and groomed at the convergence node.
4.10.2 Signal Flow and Timeslot Allocation
The services of user M and user N are transmitted from the access nodes NE2 and NE4
respectively to the convergence node NE1 through the Ethernet transparent transmission boards.
VoIP and HSI services carrying different C-VLAN IDs are tagged with different S-VLAN IDs.
The service data is isolated and exchanged at Layer 2 through S-VLAN filtering.
4.10.3 Configuration Process
An EVPLAN service (IEEE 802.1ad bridge) and the corresponding S-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.
