The committed burst size (CBS) parameter specifies the maximum burst size that can be transmitted by the source at the CIR while still complying with the CIR. If the transmitted burst is lower than the CBS value, the packets are marked as in-profile by the meter to indicate that the traffic is complying with meter configured parameters.
The operational CBS set by the system is adapted from the user configured value by using the minimum constraint.
See Table: Supported hardware rates and burst step sizes for CIR and PIR values on the 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-T for information about the burst parameter step-size.
