Monitoring Iscsi Traffic Flows - Dell S4820T Configuration Manual

Figure 55. iSCSI Optimization Example

Monitoring iSCSI Traffic Flows

The switch snoops iSCSI session-establishment and termination packets by installing classifier rules that
trap iSCSI protocol packets to the CPU for examination.
Devices that initiate iSCSI sessions usually use well-known TCP ports 3260 or 860 to contact targets.
When you enable iSCSI optimization, by default the switch identifies IP packets to or from these ports as
iSCSI traffic.
You can configure the switch to monitor traffic for additional port numbers or a combination of port
number and target IP address, and you can remove the well-known port numbers from monitoring.
