To view a summary of existing VCEs

  1. Access Virtual Connection â–¶VCE â–¶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 â–¶VCE â–¶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".
