E810 - does is support breakout cables?

[clong10]

Hi,

I would like to connect a card with 1 x 100Gb qSFP28 to another device with 4 x 25Gb SFP28s. The other device is using the NICs in an Intel IceLake D 1700 series CPU. Is there a firmware available for the E810 to support splitting it into 4 x 25Gb ports from a single QSFP28?

Also, is there a configuration tool for the e810 as we can only find one for the XL710

Hi clong10,

Thank you for posting in Intel Ethernet Communities

We have a E810 product features matrix available which you can refer list of feature support by the software drivers.

For the E810 configuration tool, please allow me to get back to you once I check with next level.

Looking forward to your reply.

Hi Irwan,

I have seen that product feature matrix but to me it's not clear - do you think "QSFP28 Direct Attach Copper breakout cables" means the card can support 4 x 25Gb from the single QSFP28?

Hi clong10,

Yes, please use the EPCT (Ethernet Port Configuration Tool) to change the port.

Videos are available for the configuration tool.
