Hi all

we've got LLQ configured on a ATM interface for a ATM-Frame relay network supporting our remote sites and i would like to put some QoS on these interfaces. A typical sub-interface configuration looks like this:

interface ATM4/0/0.53 point-to-point

bandwidth 384

ip address

ip summary-address eigrp 100 190

ip policy route-map deny-dr

pvc 98/66

ubr 427

encapsulation aal5snap


service-policy output llq


Policy Map llq

class highpriority

priority percent 50

class mediumpriority

bandwidth percent 30


class class-default



What we're finding is that traffic in the highpriority class still gets affected when someone does a large file transfer which is in the default class. Have we implemented the service-policy output in the correct place (sub-interface) or should it be in the vc? Could it be anything else?
