Hello Ammad:

This is not possible. You can create a default QoS policy that will apply to a network and thus to the internal ports created on this network.

When you create a FIP, a port on the external network is created and this port receives a QoS policy (the default policy). However, the FIP QoS driver reads the FIP QoS policy, not the associated FIP port QoS policy. That means, for now, what you need is not possible.

Regards.

You can mark QoS policy as default for the project: https://
docs.openstack.org/api-ref/network/v2/index.html?expanded=create-qos-policy-
detail#qos-default-extension
But TBH I'm not sure if that will work with FIPs - You should test it and if
that will not work, probably You can open bug for Neutron about that :)
