Viewing RAM Log Entries Counter Using the CLI Commands
The following table summarizes the equivalent CLI commands for setting fields displayed in the
General Settings page.
The following is an example of the CLI commands:
Optimizing iSCSI
iSCSI is a communication protocol used for sending data between file servers and storage disks. The file
servers are called initiators and the disks are called targets. You can optimize iSCSI flow by setting
Quality of Service frame priority parameters in the device. The device can also intercept iSCSI frames
and provide information about iSCSI communications (called sessions).
Configuring iSCSI Global Parameters
The iSCSI Optimization Global Parameters page includes parameters that affect how the device
handles iSCSI frames.
iSCSI can be configured for QoS. In the iSCSI Optimization Global Parameters page, you must enable
iSCSI, set its classification to CoS or DSCP. You may also enable Remark to change the DSCP or Cos
user priority field in the packet. In the QoS pages, you can then set the queueing to strict priority or
WRR, and then map the CoS or DSCP to the desired queue. You set the queueing in the Qos Queue
Settings page, and you map to queues in the QoS CoS to Queue or DSCP to Queue pages.
Be careful when setting QoS parameters. For example, if you set the queueing to WRR and set a low
weight, iSCSI traffic will be dropped whenever there is an overload.

Parameters in the tree view.
