# Setting Up Virtual Connection Endpoints (VCEs)

**To view a summary of existing VCEs**

1. Access **Virtual Connection ▶VCE ▶Configuration**.

A list of all existing VCEs and their current status is displayed.

---

***Note:** A type Tunnel VCE will create an implicit VCA which can be included within another VCA. Also, a VCE with both TP A and TP Z ports configured as external will generate an implicit VCA.*

For more information on specific parameters, refer to the following table.

**VCE Configuration and Status (Virtual Connection ▶VCE ▶Configuration)**

| Parameter | Description |
| --- | --- |
| VCE Name | A name that uniquely identifies the VCE on the Skylight element: LX. |
| TPID | The TPID (Tag Protocol Identifier). Specifies the type of VLANtagging used in the frames that will be handled by this VCE. Available tag protocol options are: - **0x8100:** C-VLAN - **0x88a8:** S-VLAN - **0x9100:** T-VLAN |
| TP A | The TP A is the Terminal Point interface. Can be: - **Internal:** Used to identify the TP as being connected to another VCE. - **External:** Used to identify the TP as being connected to an external port. |
| TP A VID | Used to indicate the VLANIDs expected for this VCE configuration. When Frame Type is 'all-to-one', this value is irrelevant, and '---' is displayed. |
| TP Z | The TP Z is the Terminal Point interface. Can be: - **Internal:** Used to identify the TP as being connected to another VCE. - **External:** Used to identify the TP as being connected to an external port. |
| TP Z VID | TP Z VID is applicable when 'vid-relay-action' is set to 'translate' or 'tag'. Only a single value for the VID may be specified. |
| Component ID | The ID of the Component into which the VCE will be attached. Specifying 0 indicates that the system shall automatically assign a component ID. |

**To add a new VCE or edit an existing VCE**

***CAUTION:** Before you can add a VCE to a Skylight module, you must add a standard logical interface to it. For details, see "Configuring Logical Interfaces".*
