Managing Ethernet Services
C H A P T E R
An Ethernet service is a method for provisioning Ethernet connectivity over a wide-area or Metro
Ethernet network. Ethernet services can provide customers point-to-point or multipoint-to-multipoint
Ethernet connectivity across a service provider's network.
Service providers set up Ethernet services for their customers at User Network Interface (UNI) ports
connecting customer equipment to their network. The actual means of transporting the customer traffic
across the service provider's network is at the discretion of the service provider. A service provider can
configure an Ethernet service to use a specified VLAN, VMAN, or PBB BVLAN as the transport method
between the UNI ports to the customer network.
Using Ridgeline, you can create E-Line (point-to-point) and E-LAN (multipoint-to-multipoint) Ethernet
services. You can select the devices and ports that make up the service, specify traffic mapping options,
create and apply bandwidth profiles, then validate the configuration and deploy it on your network.
For Ethernet services using VLAN or VMAN transport methods, Ridgeline adds the UNI ports to the
transport VLAN/VMAN on the devices where it is configured. For Ethernet services using a PBB
BVLAN as the transport method, Ridgeline creates the SVLANs or CVLANs, maps an ISID to an
SVLAN, adds the UNI ports to the SVLAN, then adds the ISID to the BVLAN. Bandwidth profiles, if
specified in the Ethernet service configuration, are applied to the UNI ports.
Information about the Ethernet services known to Ridgeline is available in Network Views displays. The
Services view provides at-a-glance information about the Ethernet services, the devices and ports where
they are configured, and details about the transport method specified for each service.

E-Line Service

An E-Line service is a point-to-point Ethernet Virtual Connection (EVC) that can be implemented in a
service provider network, as illustrated in Figure 47. E-Line services can be created to support Ethernet
Private Line (EPL) and Ethernet Virtual Private Line (EVPL) services.
In an E-Line service, two UNI ports connected to customer equipment (CE) devices form the endpoints
for the service. Customer traffic entering the service provider network at one UNI port is associated
with the EVC. The UNI ports are associated with each other so that customer traffic in the E-Line
service is exchanged only between the two UNI ports.
