Figure 8.2.142-1: NW-TT Port Number
The Port Number value may refer either to an Ethernet port or an IEEE PTP port and it shall be encoded as an Unsigned16 binary integer in octets 7 and 8. Octets 5 and 6 shall be set to all zeros.
For Ethernet type PDU Sessions, it is assumed that the PTP port number is the same as the associated Ethernet port number.
