[no] iscsi cos {enable | disable | dot1p vlan-priority-value [remark] | dscp dscp-value
[remark]}
• enable: enables the application of preferential QoS treatment to iSCSI traffic so that iSCSI packets are scheduled in the switch
with a dot1p priority 4 regardless of the VLAN priority tag in the packet. The default is: iSCSI packets are handled with dotp1
priority 4 without remark.
• disable: disables the application of preferential QoS treatment to iSCSI frames.
• dot1p vlan-priority-value: specifies the virtual local area network (VLAN) priority tag assigned to incoming packets in an
iSCSI session. The range is from 0 to 7. The default is: the dot1p value in ingress iSCSI frames is not changed and the same priority
is used in iSCSI TLV advertisements if you do not enter the iscsi priority-bits command (Step 10).
• dscp dscp-value: specifies the DSCP value assigned to incoming packets in an iSCSI session. The range is from 0 to 63. The
default is: the DSCP value in ingress packets is not changed.
• remark: marks incoming iSCSI packets with the configured dot1p or DSCP value when they egress the switch. The default is: the
dot1 and DSCP values in egress packets are not changed.
