Here is a snippet from http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/qos_frhqf_support.html Policy Map and Interface Bandwidth In HQF, a policy map can reserve up to 100 percent of the interface bandwidth. If you do not assign an explicit bandwidth guarantee to the class-default class, you can assign a maximum of 99 percent of the interface bandwidth to user-defined classes and reserve the other 1percent for the class-default class. --------------------------------------------------------------------------------Note If you are migrating to Cisco IOS Release 12.4(20)T and the configured policy map allocates 100 percent of the bandwidth to the user-defined classes, an error message appears in the console after booting the HQF image. The message indicates that the allocated bandwidth exceeds the allowable amount, and the service policy is rejected. In HQF, you must reconfigure the policy to account for the minimum 1 percent bandwidth guaranteed for the class-default. Then you can apply a service policy to the interface. Hope this helps!

I am sure am missing something simple here and just can't see the wood for trees at this time at night. Can you help?
