I have tried to apply the following to an ATM subinterface under the PVC, but it is not accepted, and does not give any error message when entering the configuration:
!
access-list 2050 deny tcp any any eq 1494
access-list 2050 deny tcp any any eq 1604
access-list 2050 deny tcp any any eq 80
access-list 2050 deny tcp any any eq 443
access-list 2050 permit ip any any

(ACLs 2004,2005,2006 and 2007 are used to select the customer)
Basically the idea is that a customer called reb, is given a cir of 2000000bps. Of this, we want Citrix, http and secure-http to be able to use upto the cir rate, but anything else will be restricted to 500000bps.
Without having the service-policy reb_limit under the class reb in service-policy policy1, all is ok, but if we try and add the reb_limit service policy to the class, the entry is accepted, but when the config is displayed, the second service-policy is not seen.
Hardware is a 7206VXR with NPE400, running 12.2(8)T1.
Are hierarchical traffic policies not allowed on ATM interfaces?

This looks like a bug to me. May be you should check the RNE of CSCdx29416 using the bug toolkit on CCO.

This is not a bug. If bandwidth needs to be reserved for some classes like reb-limit, the PVC needs to be configured with ATM traffic shaping such as VBR, ABR or CBR. Furthermore, only 75% of the PVC bandwidth can be reserved by default. If you need to reserve more, you will have to use the PVC command: max-reserved-bandwidth.
Have a look to the following URLs for more information:

Thanks for the replies. It is not a bug. It appears that hierarchical policies are not valid on the 72xx unless the NSE is used. It is only available on the 75xx! (TAC response)
