CBWFQ on ATM interfaces


I've been playing around with CBWFQ on ATM interfaces and noticed some strange output:

ATM main interface - can apply service policy and see counters incrementing on 'sh policy-map int' so this seems OK

ATM sub interface - cannot apply service policy to subinterface so apply to main interface. However cannot see any counters incrementing on 'sh policy-map int' so suspect this is not doing anything (similar to applying service policy to FR interface on 7200 without applying via FR map-class)

I've only tried this on 7200 routers so suspect its something to do with hardware and the 12.2S IOS train.


Does anyone have any details on what does/does not work for applying service policies on ATM interfaces on the CCIE SP lab hardware?
