DP83869HM: In Bridge Mode, where could we find the information about the link capabilities??

Hi Gorka,

Thank you for reaching out to us, I'll be more than happy to assist you. Could I ask what your primary goal is? The snippet you sent is referring to RGMII In-band signaling. Please refer to the RGMII Standard for more information. /cfs-file/__key/communityserver-discussions-components-files/138/6661.RGMIIv1_5F00_3.pdf 

However if you have register access, you can easily check Link status, speed, and many more statuses in the registers. What specific information are you searching for?

Regards,

Alvaro

Hi Alvaro,

We are using SFPs RJ45 SGMII 10/100/1000. The DP83869HM is in the middle. It works in bridge mode, RGMII to SGMII. ¿In this situation, in which registers of the DP83869HM are accessible by MDIO, we could know the capabilities of the link?

Thanks,

Gorka

Hi Gorka,

Reg 0x5 & 0xA can be read to see what the Link-Partner advertised speeds are.

Reg 0x11 tells the current link speed & status. (Link status can also be read from Reg 0x1)

Does this answer your question?

Regards,

Alvaro
