25 Quality of Service (QoS) Overview The Dell Force10 operating software (FTOS) commands for quality of service (QoS) include traffic conditioning and congestion control. This chapter contains the following sections: • Global Configuration Commands • Policy-Based QoS Commands Global Configuration Commands • qos-rate-adjust • service-class dot1p-mapping qos-rate-adjust By default, for rate policing and rate shaping, FTOS 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 policing, and rate shaping calculations. Range: 1-31 Defaults QoS rate adjustment is disabled by default, and no qos-rate-adjust is listed in the running-configuration.
