125ms is the recommended interval for Data Traffic
If you have time sensitive traffic like Voice the recommended Tc is 10 ms Regards, Tyson Scott - CCIE #13513 R&S, Security, and SP Managing Partner / Sr. Instructor - IPexpert, Inc.

Is the 125ms just a good base? If you're measuring in ever smaller intervals, I assume that keeps actual transmission rates closer and closer to the CIR. Can you name some reasons to make it larger or smaller? On Tue, May 25, 2010 at 2:33 PM, Tyson Scott <[email protected]> wrote: Correct, You cannot configure Tc yourself.

IOW, the CIR is the number that truly matters, and the different values you enter for Burst will just affect what Tc ends up being for measurement?
