The above requirement can be achieved using either of the two approaches.
Approach without explicit ECN match qualifiers for ECN packets:
!
ip access-list standard dscp_50
seq 5 permit any dscp 50
!
ip access-list standard dscp_40
seq 5 permit any dscp 40
!
ip access-list standard dscp_50_non_ecn
seq 5 permit any dscp 50 ecn 0
!
ip access-list standard dscp_40_non_ecn
seq 5 permit any dscp 40 ecn 0
!
class-map match-any class_dscp_40
match ip access-group dscp_40_non_ecn set-color yellow
match ip access-group dscp_40
!
class-map match-any class_dscp_50
match ip access-group dscp_50_non_ecn set-color yellow
match ip access-group dscp_50
!
policy-map-input pmap_dscp_40_50
service-queue 2 class-map class_dscp_40
service-queue 3 class-map class_dscp_50
Approach with explicit ECN match qualifiers for ECN packets:
!

seq 15 permit any dscp 50 ecn 3
!
ip access-list standard dscp_40_ecn
seq 5 permit any dscp 40 ecn 1
seq 10 permit any dscp 40 ecn 2
seq 15 permit any dscp 40 ecn 3
!
ip access-list standard dscp_50_non_ecn
seq 5 permit any dscp 50 ecn 0
!
ip access-list standard dscp_40_non_ecn
seq 5 permit any dscp 40 ecn 0
!
