QoS profile: Egress Max of Tunneled Traffic + Egress guaranteed of Clear(Regular) Text Traffic > Egress Max of Interface

[ThomasX]

Hi all,

I have some Platform: PA-850, PA-820, ...

I have configure QoS profile and apply QoS profile to interface (ethernet1/1) as attach files.

When configure QoS profile then: Egress Max of Tunneled Traffic + Egress guaranteed of Clear(Regular) Text Traffic > Egress Max of Interface

But, some Platforms then commit -> OK, some Platform then commit -> error.

Could you help me resolve this problem and explain to our customer 🙂

Thanks,

ThomasX

In Bangkok_Office_QoS policy, you have set the max and guaranteed to be 50Mbps. 

You attached that profile to both a tunnel, AND cleartext traffic. However, you have only allocated 50 Mbps for Eth1/1 when you need at least 100 (the sum of both types of traffic you are using the QoS feature for).

See attached photo examples. In my example, my maximum egress on eth1/3 needs to be at least 500Mbps to support the 250 maximum of each cleartext/tunnel QoS. However, if you don't set a maximum, then you will need the sum to be at least the guaranteed egress, in my case, 400 Mbps. 

Be sure you enable QoS only on egress interfaces, and that the maximum bandwidth doesn't exceed the ISP perimeter pipe, also.  See here for other examples, where you will see the sum of guaranteed/max egresses profiles do not exceed what is allocated on the interface.
