By using the following commands I can set/unset a port:

openstack port set --qos-policy qos_policy_name "network_id"

openstack port unset --qos-policy "network_id"

But the issue is I cannot find the proper way to set/unset a port.

I see this document:

And I see the module has this method:

But I don't see any more documents to see how to do that and what parameters are required.

Can you help me?
