Intel network adapter such as I340 and I350 supports IEEE 1588 (hardwawre time stamping), You may refer to product briefes below ,look for IEEE 1588 protocol under the ethernet feature
1) I340 server adapter http://www.intel.ph/content/dam/doc/product-brief/ethernet-i340-server-adapter-brief.pdf
2) I350 server adapter Intel® Ethernet Server Adapter I350: Product Brief
Hope these information helps.
thank you for the quick reply. I have a few follow-up questions:
Is it also possible to have these hardware timestamps for non-PTP packets using the given adapters?
Because I am looking for a solution that does both synchronization via IEEE1588 and precise timestamping for other incoming packet.
You may refer to Question #6, FAQ about IEEE 1588 at http://www.intel.com/content/dam/www/public/us/en/documents/faqs/ieee1588-faq.pdf. As stated "Some Ethernet NICs that support PTP only time stamp PTP packets and not all Ethernet traffic"
Hope this helps.
thanks for your effort. I have already found this FAQ, but tried to get concrete model names.
Knowing that some NICs support stamping Ethernet packets doesn't help, because I need actual model names. Otherwise I have to purchase each model and test. Shouldn't there be a resource by Intel to find out, which NIC supports that?
The I340 and I350 Server adapter (Please refer to product brief) supports IEEE 1588.
1) I340 series server adapter http://www.intel.ph/content/dam/doc/product-brief/ethernet-i340-server-adapter-brief.pdf
I340-T4 server adapter Model : E1G44HT
I340-F4 server adapter Model: E1G44HF
2) I350 series server adapter
I350T2 (Dual Port)
I350T4 (Quad port)
• Fiber connection:
I350F2 (Dual Port)
I350F4 (Quad port)
Hope this helps.
The Intel(r) Ethernet Server Adapter I210-T1 also supports IEEE-1588 as well. (Technically, it also supports AVB - audio video bridging).
The datasheet for the silicon on the card outlines the capabilities of the silicon (The Intel(r) Ethernet Controller I210 Intel® Ethernet Controller I210: Datasheet).
Actually I now got a confirmation from this post: How do hardware timestamps (hardstamps) work - Network Engineering Stack Exchange
You were all correct with the I340 and I350 support timestamping for PTP. But only the I340 series supports timestamping of all Ethernet traffic.
We already have the I350 at out lab and when I tried to use the hardstamping, it only worked for PTP traffic, so I can at least confirm the information on I350.
