BPI-R3 SFP1, how to enable?

Hello, What is the trick to get the SFP1 port enabled? I see that SFP2 is bridged to eth1, BR-LAN, this is working good. I thought I could somehow bridge eth0 and SFP1, via coping the SFP2 settings. I did use a different static subnet for SFP1, instead of the SFP1 IP settings. This is confusing…

root@OpenWrt:/# brctl show br-wan

bridge name bridge id STP enabled interfaces

br-wan 7fff.1ee79636fa84 no lan0

                       eth1

root@OpenWrt:/#

root@OpenWrt:/# brctl show br-lan

bridge name bridge id STP enabled interfaces

br-lan 7fff.1ee79636fa84 no lan4

                      rax0

                      lan2

                      lan5

                      ra0

                      lan3

                      lan1

  1. SFP1 is for WAN port, it’s eth1
  2. SFP2 is for lan port, it’s lan5

the SFP modules only work at 2.5Gbps. the CPU’s mac seeting is forcing link up 2.5Gpbs.

Thanks for explaining this!
