Bandwidth policy- graph problem

[savioneves]

Hello everybody,
I am plotting a graph about the traffic of a client, but in certain moments the traffic is higher than the bandwidth policy of the client. For example, the bandwidth policy is 45Mb/s and the traffic shows 110Mb/s, and the duration is very short. This doesn't happen with all the clients, until today I only saw this happenning with 3 clients, so I thought it could be a bug with cacti. Does anyone have passed through this problem?
Best regards

You will have to check the native SNMP data returned by the clients in that very moment of a failure. Hrd to debug ...

It seems that this traffic occurs, because cacti is getting the values before the application of the policy. Does anybody know how to get the values after the application of the policy?

I was looking for some mib variable with the same funcionality of the in/out bits(64-bit counter) implemented in cacti, but with the collecting realized after the application of the policy, I found the cbQosCMPostPolicyByte64 of the CISCO-CLASS-BASED-QOS-MIB. However the results obtained are very different, does anybody know why? Does anybody know another mib variable that could sastify my needing?
