Hi,
I have a RUT XR1 running firmware 7.03.3 with SFP WAN port configured as LAN.
It happens now from time to time that this port stops to work, so the other end device doesn't respond anymore.
The only way to recover it that to reboot the router. From the log I've extracted this part:
Mon Mar 27 16:04:35 2023 kern.notice Port link state of port LAN3 changed to UP
Mon Mar 27 16:04:35 2023 kern.notice Port speed for port LAN3 changed to 1000 baseT
Mon Mar 27 16:04:43 2023 kern.notice Port link state of port LAN3 changed to DOWN
Mon Mar 27 16:04:46 2023 kern.notice Port link state of port LAN3 changed to UP
Mon Mar 27 16:04:46 2023 kern.notice Port speed for port LAN3 changed to 1000 baseT
Mon Mar 27 16:10:31 2023 kern.notice Port link state of port LAN3 changed to DOWN
Mon Mar 27 16:10:33 2023 kern.notice Port link state of port LAN3 changed to UP
Mon Mar 27 16:10:33 2023 kern.notice Port speed for port LAN3 changed to 10 baseT
Mon Mar 27 16:10:39 2023 kern.notice Port link state of port LAN3 changed to DOWN
where it seems that the SFP port is trying to negotiate port speed down to 10 base T unsuccessfully.
Can you please help me addressing this problem?
Thanks
Kind regards
