Enabling ECN marking on Cisco nexus 3064

Hi,

I have a requirement to enable ECN marking on CIsco nexus 3064 switch. ECT(0) traffic is being switched.

 

Tried the below configs, But not quite helping.

==================================

n# sh policy-map type network-qos nq_pm_1

  Type network-qos policy-maps

  ===============================

  policy-map type network-qos nq_pm_1

    class type network-qos nq_cm_1

 

      mtu 1500

      congestion-control random-detect ecn

    class type network-qos class-default

 

      mtu 1500

     congestion-control random-detect ecn

 

n# sh run | beg "system qos"

system qos

  service-policy type qos input iscsi

  service-policy type network-qos nq_pm_1

 

 

n# sh policy-map type queuing pqu

  Type queuing policy-maps

  ========================

  policy-map type queuing pqu

    class type queuing cqu

      random-detect minimum-threshold 10 packets maximum-threshold 350 packets

      bandwidth percent 50

    class type queuing class-default

      bandwidth percent 50

      random-detect minimum-threshold 5 packets maximum-threshold 5 packets

 

n# sh run int e1/21

!Command: show running-config interface Ethernet1/21

!Time: Tue Apr 29 09:04:35 2014

version 5.0(3)U5(1b)

interface Ethernet1/21

  no switchport

  service-policy type queuing output pqu

  ip address 15.0.20.1/24

 

what could possibly be missing?

 

Thanks

Jose.
