strange error message when applying policy map to interface

We are trying to apply a Policy Map to our Multilink interface on our MPLS router using the "service policy" command.

Each time we try to apply the policy, we get the following error message

" GAMPLSRTR01(config-if)# service-policy output CE_EGRESS_QUEUING

Insufficient bandwidth for new remaining percent (50%)

Suspending service policy CE_EGRESS_QUEUING on Multilink1

GAMPLSRTR01(config-if)#

We are not sure what this means. We have tried un-applying and then re-applying the policy, but always get the same error.

Here is the policy configuration:

policy-map CE_EGRESS_QUEUING

class NMC

shape average percent 1

bandwidth remaining percent 1

random-detect dscp-based

random-detect exponential-weighting-constant 1

random-detect dscp 16 100 200 10

random-detect dscp 48 200 300 10

service-policy NMC_CLASSIFICATION

class COS2

shape average percent 24

bandwidth remaining percent 24

random-detect dscp-based

random-detect exponential-weighting-constant 1

random-detect dscp 26 200 300 10

random-detect dscp 28 100 200 10

class COS3

shape average percent 25

bandwidth remaining percent 25

random-detect dscp-based

random-detect exponential-weighting-constant 1

random-detect dscp 18 200 300 10

random-detect dscp 20 50 100 10

class COS4

shape average percent 50

bandwidth remaining percent 50

random-detect dscp-based

random-detect exponential-weighting-constant 1

random-detect dscp 0 100 200

We just started receiving this error when we flash a new IOS image to the box. The new image is "12.4(24)T". We had formerly been running version "12.4(9)T" and had been told that there was a bug in the code,and to proceed with the new code.

Re: strange error message when applying policy map to interface

By default, the interface allows you to reserve up to 75% of the bandwidth and looking at your numbers, you are reserving 100% between the 4 classes.

The command max-reserve bandwidth

http://www.cisco.com/en/US/docs/ios/interface/command/reference/ir_l2.html#wp1017628

allows you to modify this value but I don't recommend any value greater than 90%. You need to allow bandwidth for control traffic and routing protocols.
