Network > Network Profiles > QoS

Add
a QoS profile to define the bandwidth limits and priority for up to eight classes of service. You can set both guaranteed and maximum bandwidth limits for individual classes and for the collective classes. Priorities determine how traffic is treated in the presence of contention.
To fully enable the firewall to provide QoS, also:
  • Define the traffic that you want to receive QoS treatment (select Policies > QoS to add or modify a QoS policy).
  • Enable QoS on an interface (select Network > QoS).
See Quality of Service TechDocs_logo_cropped.png for complete QoS workflows, concepts, and use cases.
QoS Profile Settings
Profile Name
Enter a name to identify the profile (up to
31
characters). The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
Egress Max
Enter the maximum throughput (in Mbps) for traffic leaving the firewall through this interface. The value is 0 by default, which specifies the firewall limit (60,000 Mbps in PAN-OS 7.1.16 and later releases; 16,000 in PAN-OS 7.1.15 and earlier releases).
The
Egress Max
for a QoS profile must be less than or equal to the
Egress Max
for the physical interface enabled with QoS. See Network > QoS.
Though this is not a required field, it is recommended to always define the
Egress Max
value for a QoS profile.
Egress Guaranteed
Enter the bandwidth that is guaranteed for this profile (Mbps). When the egress guaranteed bandwidth is exceeded, the firewall passes traffic on a best-effort basis.
Classes
Add
and specify how to treat individual QoS classes. You can select one or more classes to configure:
  • Class
    —If you do not configure a class, you can still include it in a QoS policy. In this case, the traffic is subject to overall QoS limits. Traffic that does not match a QoS policy will be assigned to class 4.
  • Priority
    —Click and select a priority to assign it to a class:
    • real-time
    • high
    • medium
    • low
When contention occurs, traffic that is assigned a lower priority is dropped. Real-time priority uses its own separate queue.
  • Egress Max
    —Click and enter the maximum throughput (in Mbps) for this class. The value is 0 by default, which specifies the firewall limit (60,000 Mbps in PAN-OS 7.1.16 and later releases; 16,000 in PAN-OS 7.1.15 and earlier releases). The
    Egress Max
    for a QoS class must be less than or equal to the
    Egress Max
    for the QoS profile.
Though this is not a required field, we recommend you always define the
Egress Max
value for a QoS profile.
  • Egress Guaranteed
    —Click and enter the guaranteed bandwidth (Mbps) for this class. Guaranteed bandwidth assigned to a class is not reserved for that class—bandwidth that is unused continues to remain available to all traffic. However, when the egress guaranteed bandwidth for a traffic class is exceeded, the firewall passes that traffic on a best-effort basis.
