Activating queueing template on N7K F2E linecard

[e.nieuwstad]

We are working on the QoS configuration on our Nexus7K. According to the documents 3 output queueing methods are supported

Configurable template-based queuing modes:

• Ingress (4q1t and 2q1t)

• Egress (1p3q1t, 2p2q1t, and 3p1q1t)

http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9402/data_sheet_c78-720322.html

it appears the template linked to the egress 1p3q1t and ingress 2q1t is active

N7K-vdc-1# sh policy-map type queuing default-4q-8e-out-policy

  Type queuing policy-maps
  ========================

  policy-map type queuing default-4q-8e-out-policy
    class type queuing 1p3q1t-8e-out-pq1
      priority level 1
    class type queuing 1p3q1t-8e-out-q2
      bandwidth remaining percent 33
    class type queuing 1p3q1t-8e-out-q3
      bandwidth remaining percent 33
    class type queuing 1p3q1t-8e-out-q-default
      bandwidth remaining percent 33
N7K-vdc-1#

N7K-vdc-1# sh policy-map type queuing default-4q-8e-in-policy

  Type queuing policy-maps
  ========================

  policy-map type queuing default-4q-8e-in-policy
    class type queuing 2q4t-8e-in-q1
      queue-limit percent 10
      bandwidth percent 50
    class type queuing 2q4t-8e-in-q-default
      queue-limit percent 90
      bandwidth percent 50
N7K-vdc-1#

However I am unable to determine how to configure a different template and specify different ingress and outgress queue types.

Any help?

Hello,

If I understand your question properly, then you want to change from default-nq-8e-policy to something like default-nq-6e-policy.  This is done in the default VDC, and under the system QoS paremater. 

N7K1(config)# system qos

N7K1(config-sys-qos)# service-policy type network-qos ?

  default-nq-4e-policy  Default 4-ethernet policy (4-drop 4-nodrop CoS)

  default-nq-6e-policy  Default 6-ethernet policy (6-drop 2-nodrop CoS)

  default-nq-7e-policy  Default 7-ethernet policy (7-drop 1-nodrop CoS)

  default-nq-8e-policy  Default 8-ethernet policy (8-drop CoS)

http://www.cisco.com/en/US/docs/switches/datacenter/sw/6_x/nx-os/qos/configuration/guide/nt_qos.html#wp1077006

Also, it needs to be said that you cannot modify the default policies, you must copy the policy using the command:

"qos copy policy-map type network-qos"

Once you build your new policy, then you must activate using the system QoS.

To copy policies refer to this document:

Hope this helps.

Thanks for the answer. After some searching I found the same as well.
