This simplified example for QoS only demonstrates the use of a single class of traffic, VxFlex OS storage
traffic. For more complex traffic priority requirements, administrators can assign multiple unique DSCP values
to the appropriate port group. Administrators may then modify the switch configuration shown in the following
sections to support additional DSCP values and queues. The DSCP value used in this example is only for
demonstrating the configuration process.
4.6.2 Switch QoS configuration
The Dell EMC Networking switches use DSCP marking to place the appropriate traffic into queues for
prioritization. This section details a simple configuration to place a higher priority on storage traffic than all
other traffic.
There is not a generic, one-size-fits-all approach to QoS and Dell EMC Networking switches provide some
customization. The strict queuing used in this example could easily be substituted with explicit bandwidth
assignments. Administrators can use this example as a starting point for their QoS strategy.
The configuration example below accomplishes the following:
