Palo Alto Bandwidth Throttling

L2 Linker

Hello Everyone,

I have a question regarding Palo Altos and bandwidth throttling. I know that the Palo Altos can do QoS to limit the bandwidth for specific applications, but can the Palo Altos just do bandwidth throttling with different networks? Say for instance, we have an office and guest network going to a Palo Alto firewall. Can you do a QoS with the Guest network so that its bandwidth doesn't go above a specific limit, say 20Mbps? Any help is appreciated.

Of course Yes. Please read this two documents:

Also you can look at the following doc as well:

and some about limitation od QoS and subinterfaces:

Hopefully this helps.

I've got a screen shot where Internal zone traffic destined for the External zone has QoS applied for 'any' application but sourced from a specific subnet within that internal zone. Is this what you're referring to?10-3-2013 9-00-44 PM.png

That was exactly what I was looking for. Though, does QoS in Palo Altos only do egress limiting or can it do ingress as well?

QoS on the PAN is for egress only traffic

Got it. I think I'm getting the handle of this. One more question, is there any functionality for dynamic QoS? Say for instance, we have our office and guest network, and our office network requires more bandwidth for whatever reason. Is there an automation available to increase the max bandwidth of the office network and lower the max bandwidth of the guest network?
