Oregano Synchronization: Not Connecting To External Grand Master Clock / Layer 2 vs Layer 3 PTP


When trying to synchronize the Oregano with an external grand master clock (the Albedo clock in this case), the oregano card is not synchronizing with the external grand master, even though all the settings are matching. Why?


One reason could be that one device is using Layer 2, whereas the other is using Layer 3. To figure out which layer it is using (the oregano card is using by default layer 3), you can check the Wireshark packets:

In the screenshot below, we can see that the Oregano card packets are using Layer 3 because of the UDP field.
