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

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.

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.
