Hi Jurgen,
I apologize for confusion, been thinking of Port ID. Indeed, the Interface ID is local ID and used in case of unnumbered interface as described in section 4.7.1.3:
Interface ID
The identifier assigned to the link by the node specified by the Node ID.
Thus it MAY be SNMP' IfIndex , as you've pointed out. The document leaves it to the implementation.
Regards,
Greg

If this is specifically a PTP Interface ID, it might be desirable to
be explicit about this and that it may be different from other numeric
interface IDs. (This is what I heard you saying, I do not know much
about PTP and surely not any details how PTP defines Interface IDs.

PS: This was actually the only operational comment I had. From an
operational perspective, it is important to know whether interface
numbers us a common or possibly different numbering scheme.
