Users Guide

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.
6 (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.
7 (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.
8 (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).
9 (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.
