Configuring QoS

Hi, I'm still a little new to Palo Alto (but familiar with QoS concepts), and right now I'm trying to understand how QoS is configured on a PA3020 in production (configured by someone else before I was with the company).

 

I can see a QoS profile called 'default', which is applied to two interfaces. However, there is no QoS policy at all.

If I understand correctly, we need a QoS policy to classify traffic. So, if that's true, does that mean that there is essentially no QoS configured on this firewall?

 

Thanks

Re: Configuring QoS

Hi @Luke_R 

Without QoS policies it works too. In this case it is then - depending on the configuration in this default profile - not really QoS but more a bandwidthlimitation.

Without QoS policies the firewalls assings class 4 to all traffic. So if you have configured a max bandwidth value for the overall profile or for class 4, then the firewall does exactly that on the interfaces where the profile is assigned. Other values in this profile are useless in your configuration (if I understood correctly your description of how it is used).

Thanks, I am seeing traffic in class 4, so what you're saying makes sense.

I really appreciate your help!
