iSCSI Overview
The Internet Small Computer System Interface (iSCSI) feature helps network administrators
track iSCSI traffic between iSCSI initiators and target systems. This is accomplished by
monitoring or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI
sessions and connections. Data from these exchanges is used to create classification rules
that assign the traffic between the stations to a configured traffic class. Packets in the flow are
queued and scheduled for egress on the destination port based on these rules.

In networks containing iSCSI initiators and targets, iSCSI helps to monitor iSCSI sessions or
give iSCSI traffic preferential Quality of Service (QoS) treatment. Dynamically-generated
classifier rules are used to direct the iSCSI data traffic to queues that can be given the
desired preference characteristics over other data traveling through the switch. This might
help to avoid session interruptions during times of congestion that would otherwise cause
iSCSI packets to be dropped. However, in systems where a large proportion of traffic is
iSCSI, it might also interfere with other network control-plane traffic, such as ARP or LACP.

The preferential treatment of iSCSI traffic must be balanced against the needs of other critical
data in the network.

You can view and manage iSCSI Optimization settings on the device. iSCSI Optimization
provides a means of giving traffic between iSCSI initiator and target systems special Quality
of Service (QoS) treatment.

In addition, if configured, the packets can be updated with IEEE 802.1 or IP-DSCP values.
This is done by enabling Remark. Remarking packets with priority data provides special QoS
treatment as the packets continue through the network.

Configure Global iSCSI Settings
To configure the global iSCSI settings on the switch:
1.
Prepare your computer with a static IP address in the 169.254.100.0 subnet, for
example, 169.254.100.201.
2.
Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on
the switch.
3.
Launch a web browser.
4.
Enter the IP address of the switch in the web browser address field.
The default IP address of the switch is 169.254.100.100.
The Login screen displays.
5.
Enter the user name and password.
The default admin user name is admin and the default admin password is blank, that is,
do not enter a password.
do not enter a password.
6.
Click the Login button.
The web management interface menu displays.
