I want to connect my BPI-R4 Pro with the SFP+ DAC cable to my Xiaomi Router BE10000 (RC01).
The link is up with “10Gbps/Full - flow control off” but soon tx disabled due to “tx_fault event timeout”.
The light of the RC01‘s SFP+ port is blinking after the module is inserted.
Using BPI official firmware (BPI-R4Pro-8X-BE14-MT76-OpenWRT24.10-DSA-251229) download from bpi docs.
The SFP+ DAC is Samzhe(山泽) 10G SFP+ DAC.
