I am trying to understand how ip qos works with FR
 and
 ATM.

 I read that both FR and ATM do per vc queueing, is
 this true?
 If I configure CBWFQ udner one fr or atm pvc, does
the
 router have two sets of queues? one set for
 different
 classes of ip packets, after the ip packet got
 dequeued from the ip layer, they will be queued
 again
 under that pvc? is it same for fr and atm?
 
 since the atm/fr vcs have cbr, vbr or cir, so they
 must have queues per pvc for cells or frames, ip
 qos
 such as CBWFQ has queues for different classes of
 ip
 packets, how do they work together?
 
 I can not find anything from cco, all of the qos
 docs
 either explain ip qos or atm/fr qos.

 thanks for any help.
 
 JJ
