[c-nsp] CoPP class-default policer

I've got a 6509 with a 720 and 12.2(18)SXD2 and am playing around with
the CoPP stuff.  I've used this page as a rough guide and my test config
is not too much different than it:

  <http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_white_paper09186a0080211f39.shtml>

However, I run into a problem when I try to apply a specific policer
to the class-default in the policy-map.  As an example, this is what
I get:

  Router(config-pmap-c)#police 32000 6000 12000 conform-action transmit exceed-action drop
  Info: pir/max-burst ignored
  Router(config-pmap-c)#exit
  Router(config-pmap)#exit
  Warning (QoS): Control Plane Interface: Problem installing policy [control-plane-policy] with class class-default. Class can only have
  'match access-group' OR
  'match ip dscp' OR 'match ip precedence' OR
  'match dscp' OR 'match precedence' OR 'match mpls exp' OR
  'match dscp' OR 'match precedence' with one of'match protocol ip' OR
  'match protocol ipv6'

I suspect I'm doing something wrong, but this CoPP stuff is new to me so
I'm a bit confused as to what that might be.  Anyone recognize this problem
and know what to look for to get around it?

FYI... apparently I'm also not calculating the max-burst correctly.  The
calculation for those values have apparently changed from earlier uses of
the rate limiter commands I'm used to.  I've tried it with other values
that don't get the 'Info: pir/max-burst ignored' message and it doesn't
seem to make a difference.

Thanks for any insight.

John
