I350-T2 PTP Hardware Timestamp on drivers

Hello, thanks for choosing Dell.

The PTP Hardware Timestamp feature in Windows drivers depends heavily on both the network adapter model and the driver version—and not all combinations support it natively

• Driver limitations: Some Intel adapters like the I350-T2 or I350-T4 support PTP hardware timestamping in theory, but the Windows driver may not expose it, even though Linux drivers do

• NDIS support: Windows uses the NDIS packet timestamping interface, introduced in NDIS 6.82, to support hardware timestamping for PTPv2 traffic. But the NIC driver must explicitly implement this support

• Adapter-specific support: Adapters like I217-V and I219-V have shown the option in Device Manager, while others (like I350) may not

• Update to the latest driver Use Intel’s latest ProSet Adapter Configuration Utility (ACU) or download the newest driver package from Intel’s site. Some users have reported success enabling hardware timestamping via ACU

• Check Device Manager Look under the adapter’s advanced properties for:

• PTP Hardware Timestamp

• Software Timestamp

• Use NDIS timestamping APIs If you're developing or testing, you can use Windows APIs to query timestamping capabilities. Microsoft’s NDIS packet timestamping guide explains how to do this

Hope this helps.
