• All dot1p traffic is mapped to Queue 0 unless you enable the service-class dynamic dot1p command
on an interface or globally.
• Layer 2 or Layer 3 service policies supersede dot1p service classes.
Policy-Based QoS Commands
Policy-based traffic classification is handled with class maps. These maps classify data traffic into eight classes. Dell EMC Networking OS
enables you to match multiple class maps and specify multiple match criteria. Policy-based QoS is not supported on logical interfaces, such
as port-channels, VLANS, or loopbacks.
