control on a per port basis. This controls how limited

bandwidth is allocated. NOT ENFORCED status indicates

that there is no admission control. Every modem that

registers with a class of service specifying a minimum

upstream rate will be admitted by the CMTS regardless of

how much aggregate bandwidth is actually available.

Users enable admission control by using the admission

control CLI
