QOS - real time bandwidth monitoring

Hi All,


I've created a generic QoS profile under Network >> QoS but when I view the graph it shows the bandwidth as being much less that I know it is.


At the moment I'm streaming music which is around 2 Mbps but the graph never goes above 0.25 Mbps


Have I missed something in the config?

I'm downloading a 5GB ISO from MS and I know I'm getting around 170Mbps via the switch CLI but the Palo Alto QoS is completely wrong...

Hello @ChrisDownes 

QoS in PA works on egress traffic only. If ethernet1/1 is your Internet interface, then the figures might be correct since you are watching the traffic to the Internet. Let's assume your LAN interface is ethernet1/2, then apply QoS on that interface as well (and compare the figures with the data from network switch.

Hello @ChrisDownes 


For QoS it is always applied to the source of the traffic.

A QoS profile will be applied on egressing packets so the profile needs to be attached to the interface where the biggest data stream is going to exit the firewall. In your case if users are receiving streaming from the internet so the biggest data flow will go from the internet to the client and the QoS profile on the client side will be applied to limit the flow.


So we should apply QoS to the PA interface which connects to the LAN
