Scheduler Shaping Rate

You use the shaping rate to set the percentage of total bundle bandwidth that is dedicated to a DLCI. For link services IQ DLCIs, only percentages are accepted, which allows adjustments in response to dynamic changes in bundle bandwidth—for example, when a link goes up or down. This means that absolute shaping rates are not supported on FRF.16 bundles. Absolute shaping rates are allowed for MLPPP and MLFR bundles only.

For scheduling between DLCIs in a MLFR FRF.16 bundle, you can configure a shaping rate for each DLCI. A shaping rate is expressed as a percentage of the aggregate bundle bandwidth. Shaping rate percentages for all DLCIs within a bundle can add up to 100 percent or less. Leftover bandwidth is distributed equally to DLCIs that do not have the shaping-rate statement included at the [edit class-of-service interfaces lsq-fpc/pic/port:channel unit logical-unit-number] hierarchy level. If none of the DLCIs in an MLFR FRF.16 bundle specify a DLCI scheduler, the total bandwidth is evenly divided across all DLCIs.

Note: For FRF.16 bundles on link services IQ interfaces, only shaping rates based on percentage are supported.
