switch(config)# interface ethernet 1/5-32
switch(config-if-range)# untagged cos 4
switch(config-if-range)# exit
2.10.2

Define a QoS map for iSCSI

switch(config)# class-map type qos class-iscsi
switch(config-cmap-qos)# match cos 4
switch(config-cmap-qos)# exit
2.10.3

Define a QoS policy map for iSCSI

switch(config)# policy-map type qos policy-qos
