[no] iscsi target port tcp-port-1 [tcp-port-2...tcp-port-16] [ip-address
address]
• 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 configure 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 specific 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 specifies 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 specific 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 flows.
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 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.
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) Configures DCBX to send iSCSI TLV advertisements.
LLDP CONFIGURATION mode or INTERFACE LLDP CONFIGURATION mode
[no] advertise dcbx-app-tlv iscsi.
