Quality of Service (QoS)
The Dell Networking operating software commands for quality of service (QoS) include trac conditioning and congestion control. QoS
commands are not universally supported on all Dell Networking Products.
Per-Port QoS Commands
Per-port QoS (port-based QoS) allows you to dene the QoS conguration on a per-physical-port basis.
Policy-Based QoS Commands
Policy-based trac classication is handled with class maps. These maps classify unicast trac 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

Usage Information
The unit of bandwidth percentage is 1%. A bandwidth percentage of 0 is allowed and disables the scheduling of
that class. If the sum of the bandwidth percentages given to all eight classes exceeds 100%, the bandwidth
percentage automatically scales down to 100%.
