User Guidelines
The
iscsi cos enable
command is used to enable an iSCSI CoS profile
(whether the default profile or one configured by using the
iscsi cos vpt/dscp
command).
When executing the
iscsi cos disable
command, iSCSI CoS configuration is
not deleted.
Use the Remark option to prioritize iSCSI traffic in the next hop switch,
which might be iSCSI-unaware.
iSCSI flows are assigned by default with a VPT/DSCP that is mapped to the
highest queue not used for stack management or voice VLAN (if the mapping
was not changed by the user). The user should also configure the relevant (vpt
to queue/dscp to queue) table to complete the setting.
Setting the VPT/DSCP sets the QoS profile that determines the egress queue
to which the frame is mapped. The switch default setting for egress queues
