Probably all current Cisco offerings? Ubiquiti industrial switches? A whole crowd of second tier vendors like Lantech or Korenix? These are just those I had direct experience with.
Of these, Cisco definitely does boundary clock on L3, on at least several models of their routers.
> In my tests with directly connected NICs the synchronization is stable to few nanoseconds, same as with PTP.
Yes network sync is piece of cake if you drop the whole network bit. That said am slightly skeptical about ns level precision with NTP. Did you measure synchronicity between the two devices via scope?
