Can anyone help explain to me the way that arp inspection packet per second limiting works when enabling burst. For example, if my config is "ip arp inspection limit rate 25 burst 3", does the switch check every three seconds to see if arp packets were beyond the threshold every second of that interval? Is it simply checking every three seconds to see if the total arp packets are above 75 for the entire interval? Is it checking every three seconds or every second for the prior three second interval?
I am having a consistent issue with multiple devices in one building violating our arp packet per second limit. Is anyone else using a burst interval, and have you come across any client hardware that consistently violates the pps limit? What is your pps limit?
Initiallywe used thedefaultsettings, ie15pps, but since themigrationof the park inWin7wehad problems(probablyWindows network discovery): %SW_DAI-4-PACKET_RATE_EXCEEDED: 16packets receivedin855millisecondsonFa0/1.
Recently Ihad auser who exceededthe threshold: %SW_DAI-4-PACKET_BURST_RATE_EXCEEDED: 279packets receivedin3 secondsonFa0/35.
The messagein the logs,suggests that ifthe thresholdis exceededper second,you can expectto see the valueof3 seconds.The thresholdwould beyour valuemultiplied bythe durationof the burstthreshold(ie64x3= 192?).I'm not sure.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
