The customer noticed that while he is passing 9 Gbps through one S6700 switch (being part of RRPP ring) and coming from a single port the CPU rises up until 60 %. When the customer stops the traffic the CPU usage drops down again to its normal values.
Big problem!!! Because is supposed that data to be forwarded using ASIC without utilizing the CPU unit. So why is the CPU at 60 % ? It is normal for this load of traffic coming just from one port ? Of course not, but what is happening?
