QoS Policies Template

QoS Policy determines how flows are queued and marked.

The QoS Policy’s SET actions determine two things:

  • What traffic class a shaped flow—whether optimized or pass-through—is assigned

  • Whether to trust incoming DSCP markings for LAN QoS and WAN QoS, or to remark them as they leave for the WAN

Use the Shaper to define, prioritize, and name traffic classes.

Think of it as the Shaper defines and the QoS Policy assigns.



  • With this template, you can create rules with a priority from 1000 – 9999. When the template is applied to an appliance, Orchestrator will delete all rules having a priority in that range before applying its policies.

  • If you access an appliance directly, you can create rules with higher priority than Orchestrator rules (1 – 999) and rules with lower priority (10000 – 19999 and 25000 – 65534).

    NOTE: The priority range from 20000 to 24999 is reserved for Orchestrator.

  • When adding a rule, the priority is incremented by ten from the previous rule. The priority can be changed, but this default behavior helps to ensure you can insert new rules without having to change subsequent priorities.

Match Criteria

  • These are universal across all policy maps—Route, QoS, Optimization, NAT (Network Address Translation), and Security.

  • If you expect to use the same match criteria in different maps, you can create an ACL (Access Control List), which is a named, reusable set of rules. For efficiency, create them in Configuration > Templates & Policies > ACLs > Access Lists, and apply them across appliances.

  • The available parameters are Application, Address Map (for sorting by country, IP address owner, or SaaS application), Domain, Geo Location, Interface, Protocol, DSCP, IP/Subnet, Port, Traffic Behavior Overlay, Fabric or Internet, and User Role (the User Role as specified in the authentication exchange with the ClearPass RADIUS server).

    NOTE: User Role options include the RADIUS User Role, User Name, User Group, User Device, or User MAC. Configuring User Role match criteria enables an EdgeConnect to automatically assign traffic steering and firewall zone policies.

  • To specify different criteria for inbound versus outbound traffic, select the Source:Dest check box.

    NOTE: Source and destination role-based policies can be configured when both source and destination users are in the same network.

Source or Destination

  • An IP address can specify a subnet; for example, (IPv4) or fe80::204:23ff:fed8:4ba2/64 (IPv6).

  • To allow any IP address, use (IPv4) or ::/0 (IPv6).

  • Ports are available only for the protocols tcp, udp, and tcp/udp.

  • To allow any port, use 0.

Wildcard-based Prefix Matching Rules

  • Even when using a range or a wildcard, the IPv4 address must be specified in the 4-octet format, separated by the dot notation. For example, A.B.C.D.

  • Range is specified using a single dash. For example, 128-129.

  • Wildcard is specified as an asterisk (*).

  • Range and Wildcard can both be used in the same address, but an octet can only contain one or the other. For example, 10.136-137.*.64-95.

  • A wildcard can only be used to define an entire octet. For example, 10.13*.*.64-95 is not supported. Use 10.130-139.*.64-95 to specify this range.

  • The same rules apply to IPv6 addressing.

  • CIDR notation and (Range or Wildcard) are mutually exclusive in the same address. For example, is not supported. Use either or

  • These prefix-matching rules apply to the following policies only: Route, QoS, Optimization, NAT, Security, and ACLs.

Handle and Mark DSCP Packets

  • DSCP markings specify end-to-end QoS policies throughout a network.

  • The default values for LAN QoS and WAN QoS are trust-lan.

Apply DSCP Markings to Optimized (Tunnelized) Traffic

  • The appliance encapsulates optimized traffic. This adds an IP outer header to packets for travel across the WAN. This outer header contains the WAN QoS DSCP marking.

  • LAN QoS – The DSCP marking applied to the IP header before encapsulation.

  • WAN QoS – The DSCP marking in the encapsulating outer IP header. The remote appliance removes the outer IP header.





Apply DSCP Markings to Pass-through Traffic

  • The appliance applies the QoS Policy’s DSCP markings to all pass-through flows—shaped and unshaped.

  • Pass-through traffic does not receive an additional header, so it is handled differently:

    • The Optimization Policy’s LAN QoS Set Action is ignored.

    • The specified WAN QoS marking replaces the packet’s existing LAN QoS DSCP marking.

    • When the packet reaches the remote appliance, it retains the modified QoS setting as it travels to its destination.
