E810-XXVDA4: Auto-negotiation doesn't work in 1000baseT/Full and 1000baseX/Full modes

[YuanYan]

Hi, 

Auto-negotiation of Salem Channel is verified in below environment.

After 2 Salem channel cards are negotiated to 25000Mb/s,

(1) Keep the settings of the card on machine A

(2) Change the supported modes of the card on machine B only. 

(3) Check if 2 cards can be negotiated to the specified modes.

Below are the results:

(1) Overall results: Auto-negotiation failed in 1000baseT/Full and 1000baseX/Full modes

	10000baseLR/Full	0x100000000000	ethtool -s ens11f0 advertise 0x100000000000	PASS

(2) Link can be up if 1000baseT/Full or 1000baseX/Full modes is set on both machine A and machine B.

Could you help to clarify this is a limitation or a bug? 

Thanks,

Yuan

Hi YuanYan,

Thank you for posting in Intel Ethernet Communities.

In order to better assist you, we recommend for you to provide below information:

1. Are the Auto-negotiation is between machine A and B, or is between machine and switch?
2. Is your machine Bios firmware and NIC driver updated to the latest?
3. Is your machine and NIC come from OEM?

You may use the Ethernet Port Configuration Tool on below link to run the command "Get" to see the supported configurations of the NIC:
