The switch is Mikrotik CSS326 and I'm concerned about errors in port n° 9 in this image :
23'428 Rx Overruns while other ports are much lower, including port n° 1 which is connected to the router.
According to this What Are "Overruns" on a Serial Interface? Rx Overruns happen when the port is receiving data at a higher speed than it can transfer them from the fifo buffer to the switch's shared memory.
So why could this happen. Is it a hardware problem at the network card of the PC connected to the port, or a software related (computer at port ° 2 also uses a particular software).
