Hi
When I power on one of my esxi hosts 1 out of the 10g ports does not come up. I have to take out sfp+ DAC cable and reinsert it then it comes up.
It does this with also my second host.
some days when i power them up, they all come up fine.
The nics are mellanox connect-4 these are brand new.
I have tried various cables and the behaviour is the same.
The switch works fine other than this. Not even a year old as well. Speeds via iperf are full line speed so no issues there.
Port one is a uplink which is connected to a 10GBe Mikrotik module
Firmware is 2.13
Has anyone else had this kind of problem.
