RE: bandwidth and shape/police in MQC

While its for a cisco 10000 router here is a good example of how
parent/child policy maps work compared to the policy map below:

http://www.cisco.com/en/US/docs/ios/12_2sb/feature/guide/3levelsch.html#wp10
77234

look at the buckets picture. From my perspective the implemenation of the
child/parent policies is the opposite to the way its configured, ie from
configuration it looks like the traffic should be tested against the parent
then flow to the child, but it isn't its the opposite way around.

Priority with Explicit Policing Rate
When a priority class is configured with an explicit policer, traffic is
limited to the policer rate regardless of congestion conditions. In other
words, even if bandwidth is available the priority traffic will not be able
to exceed the rate specified with the explicit policer.
policy-map p1
class c1
priority
police cir 1000000 conform-action transmit exceed-action drop

im making the assumption that it is the same with shape/bandwidth ( I see no
reason why not)

I think BW is the minimum BW guaranteed for the class of traffic in this
case and shaping would be based on interface BW not BW# defined under
policy-map. Please correct if wrong.
