I've noticed some random disconnects with my 10g network connection.
The setup is:
FreeBSD 11.0 Server <-> Chelsio T520-SO-CR 10g nic <-> FiberStore DAC cable <-> TP Link T1700G-28TQ
I see these in my dmesg on FreeBSD
cxl0: link state changed to DOWN
cxl0: link state changed to UP
I also see similar error logs on the switch:
3 2017-05-16 17:45:21 LinkScan level_5 Te1/0/25 changed state to up.
4 2017-05-16 17:45:20 LinkScan level_5 Te1/0/25 changed state to down.
It seems to happen at least once a day.
This was causing a big problem on my FreeBSD server as the disconnects were triggering the DHCP client. This caused my jails to lose their IP Address and then my network services started failing. I've worked around it by configuring the server with a static IP instead of using DHCP, but I'd still like to figure out whats going on.
Has anyone seen this kind of behavior before?
