Service Manual

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.
You can send iSCSI TLVs either globally or on a specified interface. The interface configuration takes priority over global
configuration.
The default is Enabled.
10. (Optional) Configures 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) Configures the auto-detection of Compellent arrays on a port.
INTERFACE mode
[no] iscsi profile-compellent.
The default is: Compellent disk arrays are not detected.
