Do you have subinterfaces on this interface?

Please post complete configuration.

I think you are trying to shape in two places. First, you are shaping in class of a policy-map, and then you are applying this policy map as a child map of another shaped policy map.

This is two level hierarchy.

Your IOS does not support this, so it writes, that you can shape only at a first level.


Policy-map LEVEL2

class HTTP

shape average 256000

class class-default

Policy-map LEVEL1

class class-default

shape average 512000

service-policy LEVEL2

I named the maps to show you which level is which. So you can shape only at first level map, not at the second level one.

For more info, refer to this document:

hope this helps.
