• ip-address species the IP address of the iSCSI target. When you enter the no form of the command, and the TCP port
to be deleted is one bound to a specic IP address, the IP address value must be included in the command.
3. Set the QoS policy that is applied to the iSCSI ows.
CONFIGURATION mode
[no] iscsi cos {enable | disable | dot1p vlan-priority-value [remark] | dscp dscp-value
[remark]}
• enable: enables the application of preferential QoS treatment to iSCSI trac 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: species 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: species 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 congured dot1p or DSCP value when they egress the switch. The default
is: the dot1 and DSCP values in egress packets are not changed.
4. Set the aging time for iSCSI session monitoring.
CONFIGURATION mode
[no] iscsi aging time time.
The range is from 5 to 43,200 minutes.
The default is 10 minutes.
5. (Optional) Congures DCBX to send iSCSI TLV advertisements.
CONFIGURATION mode or INTERFACE mode
[no] advertise dcbx-app-tlv iscsi.
You can send iSCSI TLVs either globally or on a specied interface. The interface conguration takes priority over global
conguration.
The default is Enabled.
6. (Optional) Congures the advertised priority bitmap in iSCSI application TLVs.
CONFIGURATION mode
[no] iscsi priority-bits.
The default is 4 (0x10 in the bitmap).
7. (Optional) Enter interface conguration mode to congure the auto-detection of Dell Compellent disk arrays.
CONFIGURATION mode
interface port-type slot/port
8. (Optional) Congures the auto-detection of Dell Compellent arrays on a port.
INTERFACE mode
[no] iscsi profile-compellent.
The default is: Dell Compellent disk arrays are not detected.
