Same problem here. I'm also wondering about some output discards on interfaces connected to some N5Ks and some firewalls. There is no policy-binding on these interfaces and the utilization is max. 70Mbit/s on a 10Gig/s interface.
Some interfaces have the same count of errors although they are connected to different devices.
Has anyone an explanation for this?

Hi
there lot of input errors on the interface
i suggest change the port n sfp n monitor this link

Hello,
thank you for your reply. But the input errors are not the errors we are wondering about. But you are right, Alioune should check the SFP/cable.
