4 Configuring Ethernet Services
4.7 Configuring VCTRUNK-Shared EVPL (VLAN) Services
When the data of multiple users without VLAN tags sent to a transmission network is transmitted
on the same VCTRUNK, the VCTRUNK-shared EVPL (VLAN) service is used to isolate the
data by adding VLAN tags. In this way, the bandwidth is shared on the SDH side.
4.8 Configuring EPLAN Services (IEEE 802.1d Bridge)
The EPLAN service (IEEE 802.1d bridge) provides a LAN solution for multipoint-to-multipoint
convergence. This service applies where the user-side data communication equipment connected
to the transmission network does not support VLANs or where the VLAN planning is kept secret
from the network operator.
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.
4.10 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.
4.11 Ethernet Port Configuration Parameters
Before configuring an Ethernet service, you need to configure the corresponding Ethernet ports.
4.12 Ethernet Service Configuration Parameters
Ethernet services can be classified into Ethernet private line services and Ethernet private
network services. Ethernet private line services include EPL services and EVPL services.
Ethernet private network services include EPLAN services and EVPLAN services.
