I'm trying to understand few things about gPTP (IEEE 802.1AS). I am using the open source implementation by AVnu (https://github.com/AVnu/gptp).
I looking on the packets using Wireshark, and they are parsed as PTPv2 packets.
Is there any protocol difference between the packets themselves that can be used to understand whether a certain traffic is gPTP or normal PTP? I know that gPTP only extends PTP, but I thought there would be a detectable difference.
