X550-T2 jumbo frame supported in Win10

[WChan5]

Dear Sir

The X550-T2 NIC mentioned the maximum jumbo frame is 15.5K, I already verify this feature in Ubuntu Linux by an industrial camera without packet loss. 

Are there any updates with the drivers of X550-T2 or any instructions to enable 15.5k jumbo frame in Win10? Thanks.

Dear Sir

Thank you for the reply.

We connect 10GigE industrial cameras to the X550-T2 controller directly without the switch.

The X550-T2 controller can only support 9K jumbo frame in WIN 10 currently, right?

Best regards,

Hello Hans,

Thank you for the patience on this matter. 

Regarding your query, the X550-T2 controller can only support 9K jumbo frame in WIN 10 currently, right?

Yes, because that is only the option available in Windows 10.

You may also refer to below information as we mentioned on our previous update (posted ‎09-05-2021 08:45 PM) from our engineering team. 

Question: How to enable 15.5K Jumbo Frame?

Answer: The only way to enable Jumbo Packet is via device properties. In the device properties, there is a Jumbo Packet item in the Advanced tap, and then enable Jumbo Packet by selecting the Jumbo Packet sizes (4088 Bytes and 9014 Bytes) on the drop-down menu.

Important Note: As described in the datasheet, once some other functions are enabled, the maximum packet size of Jumbo Packet is limited to 9.5KB (9014 Byte payload + other information in the Jumbo packet).

The 9014B packet size is usually a common maximum value to MTU(Maximum Transmission Unit) of an Ethernet port, others that are over 9014KB can be considered as Super Jumbo Packet. Performance and latency may be impacted by the increase in MTU.

Feel free to let us know if you have additional questions. 

We will wait for your reply within 3 business days in case we don't hear from you, we will proceed closing this request.
