Set the QoS policy that is applied to the iSCSI flows.

iscsi cos {enable | disable | dot1p vlan-priority-value [remark] | dscp dscp-value [remark]}

To disable the QoS policy, use the no iscsi cos dscp command.

Parameters

enable	Enter the keyword `enable` to allow the application of preferential QoS treatment to iSCSI traffic so that the iSCSI packets are scheduled in the switch with a dot1p priority 4 regardless of the VLAN priority tag in the packet. The default is: the iSCSI packets are handled with dotp1 priority 4 without remark.
disable	Enter the keyword `disable` to disable the application of preferential QoS treatment to iSCSI frames.
dot1p vlan-priority-value	Enter the dot1p value of the VLAN priority tag assigned to the incoming packets in an iSCSI session. The range is from 0 to 7.
