I recently upgraded my core network from 1G to 10G and after the upgrade I
have noticed that my 10G switch during peak traffic (1500mbps, 100,000pps)
seems to be dropping traffic for a split second across all ports and all
vlans. I immediately replaced the switch with a different brand/model and
the problem persists.
Sometimes traffic drops to zero, others it drops to 50%, problem is very
random but seems to occur with much more frequency during high PPS (pushing
high traffic / iperf does not induce problem)
Could this be MTU? I've tried flow control, hard code duplex, stp on/off etc
I'm at a loss any ideas?
