Per-Tunnel QoS for DMVPN

Hello, i am designing a QoS policies for optimize the network for business traffic so this is my first idea:

​

class-map match-all PRUEBA

match ip dscp cs1

!

policy-map SCAVENGER

class PRUEBA

bandwidth remaining percent 1

random-detect

class class-default

bandwidth remaining percent 99

random-detect

policy-map shape_2m

class class-default

shape average 2000000

service-policy SCAVENGER

policy-map shape_5m

class class-default

shape average 5000000

service-policy SCAVENGER

​

​

this policies would be applied to the hub router to limit the traffic of the application that i previusly mark with CS1 (scavenger), and the other traffic (BE) would has their bandwidth (99%), so the QoS will be applied on each tunnel using nhrp groups, this groups will be configured based on the capacity of the spoke's links.

this configuration could function that i was intended?

what do you recommend me?
