Configuring iSCSI Optimization

To configure iSCSI optimization on a switch, follow these steps:
Step Task
1 Globally enable iSCSI optimization.
Default: Enabled.
2 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
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.
3 Set the QoS policy that will be applied to iSCSI flows,
where:
• enables the application of preferential QoS
enable
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
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
priority-bits
• dscp dscp-value
assigned to incoming packets in an iSCSI session.
Range: 0 to 63. Default: The DSCP value in
ingress packets is not changed.
• marks incoming iSCSI packets with the
remark
configured dot1p or DSCP value when they egress
the switch. Default: The dot1and DSCP values in
egress packets are not changed.
4 Set the aging time for iSCSI sessions.
Valid values: 5 to 43,200 minutes.
Default: 10 minutes.
