Hi Vince,
I can only find that three-level hierarchies are supported with
policing:
http://www.cisco.com/en/US/products/ps6350/products_configuration_guide_
chapter09186a00804559b1.html
Duane is configuring shaping, that's why I mentioned the two-level
hierarchy feature.
Regards,
Henk

Hi Duane,
I've been reading the following link after I got home:

It seems that you can only build a two level hierarchy, see the text
from the link above:
If you want to use CBWFQ with the Class-Based Traffic Shaping mechanism,
the following conditions must be met:
*A secondary-level (child) policy map must be created. This
secondary-level (child) policy map is then used to configure CBWFQ by
enabling the bandwidth command.
*Traffic shaping must be configured in the primary-level (parent) policy
map.

Henk

Hi Henk
Yup, that's what I've found. If I put shaping in the aggregate policy
for each BU and apply the aggregate as a policy then it is accepted. If
I do the same, but apply the Global-Egress policy it tells me "GTS : Can
be enabled only at the first level".
If I apply the aggregate policy it seems to be fine, however that isn't
in line with the cisco documentation on three-level hierarchy policy.

Hi Duane,
Looking at your configuration you'll need more shaping configuration in
your deeper nested policy-maps. The Global-Egress policy-map is
configured with shaping, but the aggregate policy-map isn't.
I've got no router to test it on to see If this is your problem.
Just my 0.02

Henk

Hi All
When I try to attach the below three-level hierarchy policy to an
interface it tells me "CBWFQ : Hierarchy supported only if shaping is
configured in this class" Any ideas if this is a code issue or am I
doing something wrong?
