Step 2 Use a regular rate-limiting algorithm on the upstream without rate shaping and see the drops of the excess bandwidth requests from this cable modem when it exceeds its peak upstream rate. See that the upstream rate received by that modem is in fact less than its configured-peak rate due to the timeouts and backoffs produced by the drop in bandwidth requests. Step 3 Enable grant shaping on the upstream channel by using the new shaping keyword extension to the token-bucket algorithm command line interface. This value should be close to the modem's peak-upstream rate. Also see the drop counts for the modem's Sid by using the show interface sid counters command and see that CMTS no longer drops the bandwidth requests from the cable modem.
