Hi, running openwrt snapshot latest from iirc yesterday. When i run my workstation on the lan1 port, all is fine. When i switch that to the sfp+ port (sfp-rj45 converter), i get wierd results and i am not sure if this is a problem with the sfp±rj45-adapter or something with openwrt.
It should be a consistent state, not with such a drops. It gets even worse when it comes to upload: Anyone an idea what could cause that? I use an active FAN so the temperature shouldnt be that hot.
Only sfp-port has 100mbit or the others too? Bpi-r4?
How does ethtool look like on this interface and related dmesg? Which module do you use here exactly? Maybe the eeprom is wrong (fallback to 100mbit maybe).
So please dump the i2c devices too
i2cdetect -l
Then
i2cdetect -y <bus-nr-found>
Then
i2cdump -y <bus-nr-found> 0x<addr>
its not 100mbit its 1gbit from the measurement. the sfp adapter has 10gbit. but i can exclude a problem with my isp, because when i use the lan1 port all is fine.

i am not sure which one related to the sfp port (eth1)
oh interesting found in dmesg:

logread is also interesting: the first lines show that the workstation used lan3 before, then got plugged in to eth1 and then a lot of errors appear. not sure if its a dhcp problem?

i dont use dnsmasq but unbound because the r4 is my own resolver with adblock.
All errors i see in below log are iv6 related,so try to disable ipv6 for now. Ipv4 got dhcp response.
Interesting is the above log where interface eth1 goes up and down. Maybe it gets solved by disabling ipv6,but normally it should not go down if ipv6 is not available.
You can also try disabling odhcp6c maybe it puts eth1 down if sending to multicast does not work
For i2c,you see the i2c-mux for i2c 2-5…sfp slots are channel 1+2 (2nd and 3rd).
disabled ipv6, all is good now 0o
maybe some sort of mis-configuration that leads to an error that leads to an overflow that leads to a crash in some part of the driver code…? xD
I guess it is the service configured to drop interface on error…so interface flap is fixed too? You can try enabling ipv6 again and just disabling the service
I made a mistake before, the first i2cdump should be i2cdetect
Thanks… fixed…
