Create VPWS
Purpose
The “Create Service” dialog allows you to create a Virtual Private Wire Service (VPWS).
The dialog supports you with service creation by proposing many default settings. A number of manual settings are required however. These are mentioned in the step explanations under “Controls (buttons, menu items, etc.)” below.
Please note:
A service created with this dialog is saved to the database but not deployed to the nodes. In order to deploy the services to the nodes you need to select the service in the VPWS tab of the ENP main window and execute “Deploy VPWS” from the “Edit” menu or from the context menu.
You can execute this command with a maximum of 5 concurrently selected services at a time.

Informational content
All dialogs
Steps | Displays the steps to create a Service. |
Summary | Displays the currently configured/selected mandatory parameters |
Controls (buttons, menu items, etc.)
Step 1 (a): Define Service, tab “Service”
Name | Specify a Name for the VPWS. A default name is proposed that can be taken over. However the name can be edited manually. Note: The Name must be unique and shall not contain characters like [ ] / | * ? { } = |
Description | Enter a description for the Service. |
Type | Specify Service Type: - VPWS (default setting shall be taken over; however, if required you can change the service type here) |
Select a Service Profile from the list of existing Service Profiles. This entry is mandatory with a TE Service Profile license option. Note: If you want to create a VPWS based on a Service Profile but need to configure some of the service parameters individually make sure to use a profile with the relevant parameter options set to “Variable” instead of “Fixed”. For details refer to Create Service Profile. | |
EVC ID | An automatically generated and assigned Ethernet Virtual Connection ID. |
Service Category | Shows the service category defined by the service profile. |
Dual Home / PW Control Word settings: | |
PW Control Word | Sets the PseudoWire Control Word to enabled or disabled. For dual home capable services the PW Control Word must be enabled. For non-dual home capable services the PW Control Word can be disabled if required. A service with PTP mode “Transparent Clock” can only be used for PTP if the PW Control Word is disabled. For PTP mode “Transparent Clock with CW” (preferred / default service category for transparent lock) the PW Control Word must be enabled. When using an EPEX1 unit in any of the involved nodes, the use of “Transparent Clock with CW” is mandatory for PTP mode “Transparent Clock”. |
Link Loss Forwarding settings: | |
Link Loss Forwarding | Click the “Link Loss Forwarding” checkbox to activate LLF for the service. When enabled, LLF will signal a local link down over the PW of a port-based VPWS and replicate the link down on the remote port. This feature is needed where the VPWS is used as a super-transparent wire service, e.g. when transporting an RSTP link over MPLS-TP. Default is “Enabled”. |
Service Supervision settings: | |
Add To Service Supervision | Click the “Add To Service Supervision” checkbox to activate the Service Supervision parameters: - Network, - Customer, - SLA. Note: These options can only be selected if Service Supervision and Reporting has been configured. If selected, this adds the service to the monitored services under the Service Supervision Service Supervision. A monitored Service must be deployed. |
Network | Select the Network attributes for the Service: - red, - green, - blue, - yellow. Note: The network is an attribute that allows coloring and filtering paths and components according to their physical implementation. Refer to Service Editor section for details. |
Customer | Select a Customer profile from the Customer Manager list. |
SLA | Select a Service Level Agreement profiles from the SLA Manager list. |
Step 1 (b): Define Service, tab “Quality of Service / Rate Limiting”

Type | This type defines the AC’s frame handling and VLAN tag handling. Select the Initiator Type and the Terminator Type from the list: - AC Port Based, No Change, - AC Port Based, Add PW Tag, - AC VLAN Based, No Change, - AC VLAN Based, Change Tag, - AC VLAN Based, Add PW Tag, - AC Untagged, No Change, - AC Untagged, Add PW Tag. Note: The type defines first the AC frame handling: - AC Port Based: The AC frame can be untagged, priority tagged or VLAN tagged. - AC VLAN Based: The AC frame must be VLAN tagged. - AC Untagged: The AC frame must be untagged. The type further defines the AC VLAN handling: - No Change: The AC frames are not modified. - Add PW Tag: Add a PW VLAN tag to the AC frames. - Change Tag: The AC VLAN ID is modified to the PW VLAN ID. The list below provides an overview of the possible configuration parameters per type: - AC Port Based, No Change: AC VLAN and PW VLAN are not shown and cannot be modified. - AC Port Based, Add PW Tag: Enter the PW VLAN: <VID PW>. - AC VLAN Based, No Change: Enter the AC VLAN: <VID ETH>. PW VLAN: takes the configured value of AC VLAN. - AC VLAN Based, Change Tag: Enter the AC VLAN: <VID ETH>, Enter the PW VLAN: <VID PW>. - AC VLAN Based, Add PW Tag: Enter the AC VLAN: <VID ETH>, Enter the PW VLAN: <VID PW>. - AC Untagged No Change: AC VLAN and PW VLAN are not shown and cannot be modified. - AC Untagged, Add PW Tag: Enter the PW VLAN: <VID PW>. | |
AC VLAN | Enter the Initiator/Terminator AC VLAN - <VID AC> Accept only tagged frames with the VLAN ID <VID AC> This parameter value is associated with the “AC VLAN Based” service type and can be modified. The valid range is 1…4089. | |
PW VLAN | Enter the Initiator/Terminator PW VLAN: - <VID PW> This parameter value is associated with the “Add PW tag” and “Change Tag” service types and can be modified. The valid range is 1…4089. If the service type is “VLAN Based, No Change”, the PW VLAN ID is copied from the AC VLAN ID and cannot be modified. | |
Port (table) | Select the AC port from the list of available ports. The ports list shows - Label, - Slot, - Port Type: Note: When selecting a port with port type “None” or “CVP”, the port type is automatically set to “PWAC”, and the “Next >” navigation button changes to “Apply Port Types >”. To confirm the port selection and apply the port type modification, click on “Apply Port Types >”. You can manually modify the port type to match the required type “PWAC”; click into the field to modify the port type. The port type cannot arbitrarily be modified. Only types that match the AC Type can be selected. Port types are updated when changing the AC Type. To revert the proposed port type modifications, deselect the port (via <Ctrl>/<Strg>-click), or select a different port, or cancel service creation. Once port types are selected, click on “Apply Port Types >” to apply the modifications to the network. When modifications have been applied, the “Apply Port Types >” button changes back to “Next >”. - VLAN Mode, - Reason (for a port not being selectable when “Show all ports” is enabled). | |
