Quality of Service (QoS)
The Dell Networking operating software commands for quality of service (QoS) include traffic conditioning and congestion
control. QoS commands are not universally supported on all Dell Networking Products.

• Policy-Based QoS Commands
• bandwidth-percentage
• description
• dot1p-priority
• policy-aggregate
• policy-map-output
• qos-policy-output
• rate-shape
• service-class bandwidth-percentage
• service-class dot1p-mapping
• service-class dynamic dot1p
• service-policy output
• service-queue
• show qos dcb-map
• show qos dot1p-queue-mapping
• show qos qos-policy-output
Per-Port QoS Commands
Per-port QoS (port-based QoS) allows you to define the QoS configuration on a per-physical-port basis.
Policy-Based QoS Commands
Policy-based traffic classification is handled with class maps. These maps classify unicast traffic into one of four classes. The
system allows 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.
bandwidth-percentage
Assign a percentage of weight to the class/queue.
Syntax
bandwidth-percentage percentage
To remove the bandwidth percentage, use the no bandwidth-percentage command.
Parameters
percentage Enter the percentage assignment of weight to the class/queue. The range is from 1
to 100% (granularity 1%).
Defaults none
Command Modes CONFIGURATION (conf-qos-policy-out)
Supported Modes Programmable-Mux (PMUX)
