Mode Global Config

iscsi cos

This command sets the quality of service profile that will be applied to iSCSI flows. iSCSI
flows are assigned by default to the highest VPT or DSCP mapped to the highest queue not
used for chassis management. Take care that you configure the relevant Class of Service
parameters for the queue in order to complete the setting.
Setting the VPT or DSCP sets the QoS profile which determines the egress queue to which
the frame is mapped. The switch default setting for egress queues scheduling is Weighted
Round Robin (WRR).
You can complete the QoS setting by configuring the relevant ports to work in other
scheduling and queue management modes via the Class of Service settings. Depending on
the platform, these choices may include strict priority for the queue used for iSCSI traffic. The
downside of strict priority is that, in certain circumstances (under heavy high priority traffic),
other lower priority traffic may get starved. In WRR the queue to which the flow is assigned to
can be set to get the required percentage.
