Figure 18-65 PW-HE Interface 
The PW-HE interface is treated like any existing L3 interface and operates on one of the following nodes:
Bridged interworking (VC type 5 or 4) node—PW will carry customer Ethernet frames with IP 
payload. The S-PE device must perform ARP resolution for customer IP addresses learnt over 
PW-HE, which acts as a broadcast interface.
IP interworking node (VC type 11)—The PW-HE acts as a point-to-point interface. Hence, there will 
be two types of PW-HE interface-PW-Ether and PW-IW. These PW’s can terminate into a VRF or 
the IP global table on SP-E.
Viewing the PW-HE configuration
To view the PW-HE configuration:
Step 1Right-click the required device in the Vision client and choose Inventory.
Step 2In the logical inventory window, choose Logical Inventory > PW-HE. The list of PW-HE interfaces 
configured in Prime Network are displayed in the content pane. 
Step 3From the PW-HE node, choose a PW-HE interface. The PW-HE interface details are displayed in the 
content pane as shown in Figure 18-66.

Working with Ethernet Services
Ethernet services are created when the following business elements are linked to one another: 
Network VLAN and bridge domain are linked through a shared EFP.
Network VLAN and VPLS instance are linked through either of the following: 
–A shared, standalone EFP.
–A shared switching entity.
Network VLAN and network pseudowire (single or multi-segment) are linked through either of the 
following: 
–A shared, standalone EFP.
–A shared switching entity. 
VPLS-EoMPLS connected via a shared access pseudowire endpoint.
Network VLAN and cross-connect are connected by a shared EFP.
Network VLAN and service link are connected by a shared EFP.
If a VPLS, network pseudowire, cross-connect, or network VLAN object is not connected to another 
business element, it resides alone in an Ethernet service. 
In releases prior to Prime Network 3.8, EVC multiplex was discovered by means of Ethernet flow point 
associations. Beginning with Prime Network 3.9, multiplex capabilities were enhanced to distinguish 
multiplexed services based on the Customer VLAN ID; that is, Prime Network 3.9 is Inner Tag-aware.
As a result, in environments in which service providers have customers with multiplexed services, an 
EVC can distinguish each service and create its own EVC representation.

  Working with Ethernet Services
Prime Network discovers Ethernet services and enables you to add them to maps, apply overlays, and 
view their properties. See the following topics for more information: 
Adding Virtual Connections to a Map, page 18-123
Applying Ethernet Service Overlays, page 18-124 
Viewing Ethernet Service Properties, page 18-126 
Adding Virtual Connections to a Map
You can add the virtual connections that Prime Network discovers to maps as required. 
To add a virtual connection to a map: 
Step 1In the Vision client, select the required map or domain. 
Step 2Open the Add Ethernet Service to map dialog box in either of the following ways:
In the toolbar, choose Add to Map > Virtual Connection. 
In the menu bar, choose File > Add to Map > Virtual Connection. 
Step 3In the Add Virtual Connection dialog box, do either of the following: 
To search for specific elements: 
a. Choose Search, and then choose a search category: EVC Terminating EFPs, Name, or System 
Name.
b. To narrow the display to a range of virtual connection or a group of virtual connections, enter a 
search string in the search field. 
c. Click Go. 
For example, if you choose Name and enter 
EFP1, the network elements that have names beginning 
with EFP1 are displayed. 
To view all available virtual connections, choose Show All and click Go. 
The available elements that meet the specified search criteria are displayed in the Add Virtual 
Connections dialog box in table format. The dialog box also displays the date and time at which the list 
was generated. To update the list, click Refresh.
NoteIf an element is not included in your scope, it is displayed with the locked device icon. 
For information about sorting and filtering the table contents, seeViewing a Table of NEs and Their 
Properties (List View), page 7-7.
Step 4In the Add Virtual Connections dialog box, select the elements that you want to add. You can select and 
add multiple elements by pressing Ctrl while selecting individual elements or by pressing Ctrl +Shift 
to select a group of elements.
Step 5Click OK. 
The virtual connection is displayed in the navigation pane and in the content area. In addition, any 
associated tickets are displayed in the ticket pane. See Figure 18-67.
