Can PANOS controll / rate limit internet downloads ?
On my squid boxes I can ratelimit and it does this by delaying acks.
Can the PA QOS do this work as well ?

This one I did not know (I am planning actually to do the same with an 80G AE Interface). So as soon you have QoS enable the max total bandwidth you can specify is 40G? But you can have multiple 40G channels and so you can also have multiple 40G QoS configurations?

I thought they removed the artificial limits to QoS with 7.1.11? Meaning, that QoS would support whatever the physical interfaces could support.
7.1.10 and earlier were limited to 1 Gbps when QoS was enabled, regardless of what the physical / aggregate interfaces could handle.
Granted, we don't have access to any ports greater than 10 Gbps, and have no switches with 10 Gbps to test with, so ...

I just tried panoram 8.0.8 set template to 5200 and tried to set Phy ae1 to 80000 max is 60000
think i confirmed this with PA support. strange and annoying !
so lose 20Gb for QOS.
or even more if you are using active / active cause you can share QOS between nodes !

Thanks for testing. Sucks that there's still an artificial limit. 😞
But, good to know the limit is much higher than we will need it to be for the next decade or so. 🙂

I would like to add that when employing Active-Active your throughput per chassis should be calculated to be less than half of the chassis maximum throughput, as the cluster is intended to be a fail-over redundancy and not a capacity increasing measure (if both systems are at 60% capacity and one fails, the remaining chassis will be at 120% and potentially also cause serious impact)
so for a cluster of PA-5280 you would ideally not exceed 34Gbps per chassis
