host1(config)#scheduler-profile 2m
host1(config-scheduler-profile)#shaping-rate 2000000
host1(config-scheduler-profile)#exit
Configure per-VC CDVT by configuring QoS profile with ATM VC queues.
4.
host1(config)#qos-profile low-cdv-q-p
host1(config-qos-profile)#atm-vc node scheduler-profile 1m

host1(config-qos-profile)#exit
Configure per-VP CDVT using shapeless VP tunnels that are used when the QoS

TIP: For ATM interfaces on ERX7xx models, ERX14xx models, and the
ERX310 router, you must specify port 0.
