Make sure you have created a QoS policy with the required access rules.
From the domain level, you assign a QoS policy to the required inline port pairs of that domain. You have to assign a QoS policy separately for inbound and outbound. Only when you assign a QoS policy, the Sensor is aware of the rules against which it should match the traffic and corresponding bandwidth that it should allow for the matching traffic. You can assign the same QoS policy to any number of inline ports that belong to the domain.
The QoS policy that you assign might belong to the domain or inherited from a parent domain. For delegated Sensor ports, you can only assign the QoS policy from the domain that owns the Sensor.
Select Intrusion Prevention → Policy Types → QoS.
Click the Assignments value of the policy that you want to assign.
The Assignments window displays. It lists the available resources for the admin domain.

Search Interfaces
To filter the list of available resources, enter a string that is part of the Available Interfaces.
Available Interfaces
Lists the Sensor resources for the admin domain. For example, if an admin domain has only Sensor ports allocated from the parent domain but no Sensor of its own, then no device-level resource is listed. Also, the items in this list are filtered based on your filter criteria.
Note
In case of Sensors in failover, the ports used for interconnection of the Sensors are not displayed. If you have assigned the QoS policy to an interconnect port, the assignment is automatically removed when you create the failover.

to move it to Selected Interface.Current Policy
The QoS policy that is currently assigned to a resource. To replace that policy with the policy that you are currently assigning, move the resource to Selected Interface.
Selected Interface (Policy Group)
Lists the Sensor resources to which you have assigned the policy.
