Configuring iSCSI Optimization
This chapter describes how to configure Internet Small Computer System 
Interface (iSCSI) optimization, which enables special quality of service 
(QoS) treatment for iSCSI traffic.
The topics covered in this chapter include:
• iSCSI Optimization Overview
• Default iSCSI Optimization Values
• Configuring iSCSI Optimization (Web)
• Configuring iSCSI Optimization (CLI)
• iSCSI Optimization Configuration Examples
iSCSI Optimization Overview
iSCSI optimization provides a means of giving special Quality of Service 
(QoS) treatment to iSCSI traffic on the switch. This is accomplished by 
monitoring, or “snooping,” traffic to detect packets used by iSCSI stations to 
establish iSCSI sessions and connections. Data from these exchanges is used 
to create classification rules to assign traffic between the stations to a 
configured traffic class. The traffic classification affects how the packets in 
the flow are queued and scheduled for egress on the destination port.
