This page shows the differences between the current clean version model with ETSI IFA011 v2.5.1 and other proposed changes:
...
| Attribute Name | Type | Multiplicity | Description | Applied Stereotypes | Attribute Type |
|---|---|---|---|---|---|
cpdId | Identifier | 1 | Identifier of this Cpd information element. | OpenModelAttribute
| attribute |
In IFA 011 and model but not in clean: layerProtocol | Enum Model has type LayerProtocol | 1..N | Identifies which protocol the CP uses for connectivity purposes (Ethernet, MPLS, ODU2, IPV4, IPV6, Pseudo-Wire, etc.). | OpenModelAttribute
| attribute |
cpRole In model this is called cpdRole to distinguish it from a cpRole | String | 0..1 | Identifies the role of the port in the context of the traffic flow patterns in the VNF or parent NS. For example a VNF with a tree flow pattern within the VNF will have legal cpRoles of ROOT and LEAF. | OpenModelAttribute
| attribute |
description | String | 0..1 | Provides human-readable information on the purpose of the CP (e.g. CP for control plane traffic). | OpenModelAttribute
| attribute |
cpProtocol | CpProtocolData | 1..N | Identifies the protocol layering information the CP uses for connectivity purposes and associated information. There shall be one cpProtocol for each layer protocol as indicated by the attribute layerProtocol. Editor's note: the attribute "layerProtocol" still needs further discussion. The info model has layerProtocol and has moved cpProtocol to sub-classes. | OpenModelAttribute
| attribute |
trunkMode | Boolean | 1 | Information about whether the CP instantiated from this CPD is in Trunk mode (802.1Q or other). | OpenModelAttribute
| attribute |

| attribute |
...
| Attribute Name | Type | Multiplicity | Description | Applied Stereotypes | Attribute Type |
|---|---|---|---|---|---|

| attribute |
vnicName | String | 0..1 | Describes the name of the vNIC this CP attaches to, e.g. eth0. It will be configured during the Vdu booting process. | OpenModelAttribute

| attribute |
vnicType Note: This is new in IFA011 v2.5.1 | Enum (create an enum called VnicType with the literals specified in valueRange ...in CAPS) | 0..1 | Describes the type of the virtual network interface realizing the CPs instantiated from this CPD.

Note: This is an Enum and would not have a valueRange specified | attribute |
| virtualNetworkInterfaceRequirements | VirtualNetworkInterfaceRequirements | 0..* | Specifies requirements on a virtual network interface realizing the CPs instantiated from this CPD. | OpenModelAttribute
| association |
IFA 011 and model both contain intVirtualLinkDesc | VnfVirtualLinkDesc (model) Identifier (IFA 011) | 0..1 | Reference of the internal VLD which this internal CPD connects to. | OpenModelAttribute
| association |
IFA 011 and model both contain order Note: Did not add this due to presence of vnicOrder | Integer | 0..1 | The order of the NIC to be assigned on the compute instance (e.g. 2 for eth2). Note: when binding more than one port to a single compute (aka multi vNICs) and ordering is desired, it is mandatory that all ports will be set with an order value. The order values shall represent a positive, arithmetic progression that starts with 0 (i.e. 0, 1, 2,..., n). | OpenModelAttribute
