I have two X650 stacked together they both have firmware XOS 18.104.22.168 v1254b5-patch1-6.
I set rate-limit flood broadcast for example 1000pps on 10G port 1:15 and I see on show ports rate-limit flood command that Flood Rate Exceeded is still increasing. The problem is that on graphs I see only 300pps of broadcast traffic the same thing is when i do show port statistics command, values of broadcast traffic are increasing about ~300pps. So I did a test and configured rate-limit flood broadcast for this port to 200000pps .. and i show ports rate-limit flood Flood Rate Exceeded is still increasing.
Maybe somebody could test it on their switches or explain to me what I'm doing wrong.
