Example: Color-marking non-ECN Packets in Different Traffic Classes The following examples both show how to mark non-ECN packets for "yellow" handling when packets with DCSP 40 egress on queue 2 and packets with DSCP 50 egress on queue 3. Non-ECN-capable packets have the ECN field in their packet headers set to 0. The first example shows how to achieve the desired configuration without specifying ECN match criteria to classify ECN-capable 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 The second example shows how to achieve the desired configuration by specifying ECN match criteria to classify ECN-capable packets: ip access-list standard dscp_50_ecn seq 5 permit any dscp 50 ecn 1 seq 10 permit any dscp 50 ecn 2 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 class-map match-any class_dscp_40 match ip access-group dscp_40_non_ecn set-color yellow match ip access-group dscp_40_ecn class-map match-any class_dscp_50 match ip access-group dscp_50_non_ecn set-color yellow Quality of Service (QoS) 932
