3.1 Terms

For the purposes of the present document, the terms given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

Sub-parameter: port parameter or user plane node parameter included into another port parameter or user plane node parameter consisting of a collection of sub-parameters. For instance, the PTP profile port parameter is a sub-parameter of the PTP instance list port parameter.

Parameter-entry: entry of a port parameter or user plane node parameter data structure supporting instantiation. For example:

– Static filtering with port-map support entry is a parameter-entry of Static filtering with port-map support entries as specified in clause 9.6B referred by a combination of MacAddress value and VID value;

– Stream filter instance is a parameter-entry of Stream filter instance table as specified in clause 9.8 referred by DS-TT port number value;

– Stream gate instance is a parameter-entry of Stream gate instance table as specified in clause 9.9 referred by StreamGateInstance value;

– DS-TT port neighbor discovery configuration for DS-TT ports instance is a parameter-entry of DS-TT port neighbor discovery configuration for DS-TT ports as specified in clause 9.10 referred by DS-TT port number value; or

– PTP instance is a parameter-entry of PTP instance list as specified in clause 9.15 referred by PTP instance ID value.

For the purposes of the present document, the following terms and definitions given in 3GPP TS 23.501 [2] apply:
