232 Configuring System InformationViewing RAM Log Entries Counter Using the CLI CommandsThe following table summarizes the equivalent CLI commands for setting fields displayed in theGeneral Settings page.The following is an example of the CLI commands:Optimizing iSCSIiSCSI is a communication protocol used for sending data between file servers and storage disks. The fileservers are called initiators and the disks are called targets. You can optimize iSCSI flow by settingQuality of Service frame priority parameters in the device. The device can also intercept iSCSI framesand provide information about iSCSI communications (called sessions).Configuring iSCSI Global ParametersThe iSCSI Optimization Global Parameters page includes parameters that affect how the devicehandles iSCSI frames.iSCSI can be configured for QoS. In the iSCSI Optimization Global Parameters page, you must enableiSCSI, set its classification to CoS or DSCP. You may also enable Remark to change the DSCP or Cosuser priority field in the packet. In the QoS pages, you can then set the queueing to strict priority orWRR, and then map the CoS or DSCP to the desired queue. You set the queueing in the Qos QueueSettings 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 lowweight, iSCSI traffic will be dropped whenever there is an overload.To open the iSCSI Optimization Global Parameters page, click System → iSCSI Optimization→ GlobalParameters in the tree view.Table 6-51.
