SCE 8080 CIR/PIR issue

Unanswered Question
Apr 2nd, 2012

Hi I create a package in SCABB  with CIR=0, PIR=3500 kbps to have bandwith control over a range of IP address in a csv file directly applied on SCE. but when i review SCA reporter Bandwith service per package, I see  4000Kbps and more in this package. Why the PIR is not working??

Example:

csv file:

client1, 1.1.1.0/24, 5

Package in SCABB:

index: 5

CIR = 0

PIR = 3500

I have this problem too.

Hello Geovanny,

Is this production environment or lab?

What kind of traffic passing through the SCE?

(Num of flows, src IPs, TCP/UDP, applications, etc.)

One possible explanation for this is that since the traffic control

starts only after the classification is completed, those pre-classified

traffic is not controlled. This is usually not a problem but some P2P

protocols may require many packets to be inspected to classify and

if there is a heavy P2P user, the traffic for the user may exceed the PIR

slightly.

I think you can check which protocol is exceeding the PIR by looking

at the report which you realized the issue.

Thanks,

Tomo
