Configuring iSCSI Optimization To configure iSCSI optimization on a switch, follow these steps: Step 1 2 3 4 Task Command Command Mode Globally enable iSCSI optimization. Default: Enabled. Configure the iSCSI target ports and optionally the IP addresses on which iSCSI communication will be monitored, where: • 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. Default: 860, 3260. Separate port numbers with a comma. • ip-address specifies 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 specific IP address, the IP address value must be included in the command. [no] iscsi enable [no] iscsi target port tcp-port-1 [tcp-port-2...tcp-port-16] [address ip-address] CONFIGURATION CONFIGURATION Set the QoS policy that will be applied to iSCSI flows, where: • 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. Default: 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 VLAN priority tag assigned to incoming packets in an iSCSI session. Range: 0 to 7. Default: The dot1p value in ingress iSCSI frames is not changed and is used in iSCSI TLV advertisements if the iscsi priority-bits command is not entered (Step 5). • dscp dscp-value specifies the DSCP value assigned to incoming packets in an iSCSI session. Range: 0 to 63. Default: 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. Default: The dot1and DSCP values in egress packets are not changed. [no] iscsi cos {enable | disable | dot1p vlan-priority-value [remark] | dscp dscp-value [remark]} CONFIGURATION Set the aging time for iSCSI sessions. Valid values: 5 to 43,200 minutes. Default: 10 minutes. [no] iscsi aging time time CONFIGURATION iSCSI Optimization | 283
