converting QoS marking ?

[pfrancis3]

Hello, on my router I am currently identifying 'cs6' marked outgoing traffic and re-marking to 'ef'.

Vice versa, when incoming 'ef' traffic comes back in to my interface, I want to convert it back to 'cs6'. Would my code below achieve this ?

Thank you for any help.

class-map match-all VOIP
 match ip dscp cs6

class-map match-all matchEF
match ip dscp ef

policy-map SUB-LEVEL
 class VOIP
    shape average percent 95
    bandwidth percent 30
    fair-queue
  set dscp cs6
 class class-default
    fair-queue
    bandwidth percent 10
    shape average percent 95
  set ip precedence 0
policy-map TOP-LEVEL
 class SHAPE-ALL
    shape average 4900000 200000
    bandwidth 4900
  service-policy SUB-LEVEL

policy-map SETcs6Toef
  class matchEF
  set dscp ef

interface FastEthernet4
 description Routerport PHYSICAL
 bandwidth 5000
 no ip address
 ip nbar protocol-discovery
 ip flow ingress
 ip flow egress
 service-policy output TOP-LEVEL
 service-policy input SETcs6Toef

No, it wouldn't.

PS:

If you would like to know what needs changing. . .

policy-map SETefTOcs6
  class matchEF
  set dscp cs6

policy-map SUB-LEVEL
 class VOIP
    shape average percent 95
    bandwidth percent 30
    fair-queue
  set dscp ef

BTW, are you sure you want to do this?  It's a rather unusual mutation.

PPS:

Some other suggestions:

policy-map SUB-LEVEL
 class VOIP
    shape average percent 95
    priority percent 30
    fair-queue
  set dscp cs6
 class class-default
    fair-queue
    bandwidth remaining percent 100
    shape average percent 95
