I installed the E810-XXVDA4T adapter in a AMD Ryzen Threadripper machine running Ubuntu 22.04.
When inserting the SPF transceiver into a SFP port, auto-negotiation is turned off off. It is also off when connected to a radio unit via the fiber. Removing the SFP transciver from the port turns auto-negotiation back on).
Executing ethtool with an active link gives the following:
#ethtool enp74s0f0np0
Settings for enp74s0f0np0:
Supported ports: [ FIBRE ]

Trying to enable auto-negotiation using 'ethtool –s enp74s0f0np0 autoneg on' does not work.
Is there a way to force auto-negotiation to be enabled?

Hi Hayat,
Please find attached the SSU log.
Note that the SFP transceiver is connected to interface enp74s0f0np0, for which auto-negotiation support is off. If I try to move the SFP transceiver to one of the other ports, the auto-negotiation support is turned off for that one.

Hi Jehake,
For dual-rate optic modules, the negotiation of the speed is handled by the module itself.
You should be able to change the advertised speed to only link with partners that will support that speed.
Kindly let us know if you have any questions.

Hayat

Hi Hayat,
We had to return the radio unit connecting to the interface for other reasons, so I have not been able to check.
In the bring up guide of the radio unit, it states that auto-negotiation must be enabled. When we get a new radio unit, I will check if that is really the case and I will come back to you.

jehake
