45 Quality of Service (QoS) The Dell EMC Networking OS commands for quality of service (QoS) include traffic conditioning and congestion control. QoS commands are not universally supported on all Dell EMC Networking products. Topics: • Global Configuration Commands • Per-Port QoS Commands • Policy-Based QoS Commands • DSCP Color Map Commands Global Configuration Commands There is only one global configuration QoS command. qos-rate-adjust By default, while rate limiting, policing, and shaping, Dell EMC Networking OS does not include the Preamble, SFD, or the IFG fields. These fields are overhead; only the fields from MAC destination address to the CRC are used for forwarding and are included in these rate metering calculations. You can optionally include overhead fields in rate metering calculations by enabling QoS Rate Adjustment. Syntax qos-rate-adjustment overhead-bytes Parameters overhead-bytes Include a specified number of bytes of packet overhead to include in rate limiting, policing, and shaping calculations. The range is from 1 to 31. Defaults Command Modes Command History QoS rate adjustment is disabled by default. CONFIGURATION This guide is platform-specific.
