Quality of Service

Quality of Service (QoS) is a set of technologies that work on a network to guarantee its ability to dependably run high-priority applications and traffic under limited network capacity. QoS technologies accomplish this by providing differentiated handling and capacity allocation to specific flows in network traffic. This enables the network administrator to assign the order in which traffic is handled, and the amount of bandwidth afforded to traffic.
Palo Alto Networks Application Quality of Service (QoS) provides basic QoS applied to networks and extends it to provide QoS to applications and users.
Use the following topics to learn about and configure Palo Alto Networks application-based QoS:
Use the Palo Alto Networks product comparison tool to view the QoS features supported on your firewall model. Select two or more product models and click

to view QoS feature support for each model (for example, you can check if your firewall model supports QoS on subinterfaces and if so, the maximum number of subinterfaces on which QoS can be enabled).
QoS on Aggregate Ethernet (AE) interfaces is supported on PA-7000 Series, PA-5200 Series, and PA-3200 Series firewalls running PAN-OS 7.0 or later release versions.
