Combine police with bandwidth in policy-map

[billmatthews]

We have an outbound QOS policy applied to a serial T1.  We have a priority reservation for voice.  For some of the remaining classes we use bandwidth remaining statements. 

policy-map qosoutbound
 class TAG-EF
  set dscp ef
  priority 480
 class TAG-AF41
  set dscp af41
 class TAG-AF42
  set dscp af42
  bandwidth remaining percent 10
 class TAG-AF31
  set dscp af31
  bandwidth remaining percent 15
 class TAG-AF21
  set dscp af21
  bandwidth remaining percent 25
 class TAG-AF11
  set dscp af11
  bandwidth remaining percent 15
.....etc....

However for one class (tag-af21) we want to enforce a bandwidth limit.   Can I combine a police cir with the bandwidth statements?

class TAG-AF21

  set dscp af21

  police cir 768000

   conform-action transmit

   exceed-action drop

  bandwidth remaining percent 25

Thanks

Bill

Yes you can police.  You consider shaping instead.  Or if you police, instead of dropping packet you might mark it down.

Hello
Even though the ios excepts the policer with the bw% I am curious how qos would read the policy?

Another option would to apply the policer on the LAN facing interface where also it can be marked for some congestion avoidance and then apply the cbwfq policy that you have posted on the wan interface from some congestion management

If I remember correctly, the later IOSs that support percentages on policers or shapers, I recall, should use its parent's bandwidth.
