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 Cisco Provider Connectivity Assurance Sensor LT-S (formerly Skylight performance element: LT/LT-S).
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 an Assurance module, you must add a standard logical interface to it. For details, see "Configuring Logical Interfaces".
