Hi,

PTPv2 UDP SYNC packets sent to port 320 are not timestamped with X710 NIC? The same packets sent to port 319 are timestamped.

I checked registers configuration under debugger after i40e_timesync_enable() is called:

PRTTSYN_CTL1.TSYNTYPE = 0x2
PRTTSYN_CTL1.UDP_ENA = 0x3

So both ports 319 and 320 should work fine.
