Administrator Guide
• tcp-port-n is the TCP port number or a list of TCP port numbers on which the iSCSI target listens to requests. You can
congure up to 16 target TCP ports on the switch in one command or multiple commands. The default is 860, 3260.
Separate port numbers with a comma. If multiple IP addresses are mapped to a single TCP port, use the no iscsi target
port
tcp-port-n command to remove all IP addresses assigned to the TCP number.
To delete a specic IP address from the TCP port, use the no iscsi target port tcp-port-n ip-address address
command to specify the address to be deleted.
• ip-address species the IP address of the iSCSI target. When you enter the no form of the command, and the TCP port you
want to delete is one bound to a specic IP address, include the IP address value in the command.
If multiple IP addresses are mapped to a single TCP port, use the no iscsi target port command to remove all IP
addresses assigned to the TCP port number.
To remove a single IP address from the TCP port, use the no iscsi target port ip-address command.
7 (Optional) 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 trac 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: species 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: species 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 congured dot1p or DSCP value when they egress the switch. The default is: the
dot1 and DSCP values in egress packets are not changed.
8 (Optional) 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.
9 (Optional) Congures DCBX to send iSCSI TLV advertisements.
LLDP CONFIGURATION mode or INTERFACE LLDP CONFIGURATION mode
[no] advertise dcbx-app-tlv iscsi.
You can send iSCSI TLVs either globally or on a specied interface. The interface conguration takes priority over global conguration.
The default is Enabled.
10 (Optional) Congures the advertised priority bitmap in iSCSI application TLVs.
LLDP CONFIGURATION mode
[no] iscsi priority-bits.
The default is 4 (0x10 in the bitmap).
11 (Optional) Congures the auto-detection of Compellent arrays on a port.
INTERFACE mode
[no] iscsi profile-compellent.
