Applying changes to a QoS policy¶

You can update or remove an existing QoS policy.

To update a QoS policy:

1. Log in to an OpenStack controller node.

2. Update the QoS policy using the neutron qos-bandwidth-limit-rule-update <qos-policy-name> command.

   Example:

   rule_id=`neutron qos-bandwidth-limit-rule-list bw-limiter -f value -c id`
   neutron qos-bandwidth-limit-rule-update bw-limiter $rule_id --max-kbps 200000
   

To remove a QoS policy:

1. Log in to an OpenStack controller node.

2. Remove from:

   • A network:

     neutron net-update <network-name> --no-qos-policy
     

   • A port:

     neutron port-update <sriov_port> --no-qos-policy
