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. Table 6-51. General Settings CLI Commands CLI Command Description logging buffered size number Sets the number of syslog messages stored in the internal buffer (RAM). port jumbo-frame Enables jumbo frames for the device. show port jumbo-frame Displays jumbo frame information for the device. The following is an example of the CLI commands: Console (config)# logging buffered size 300 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. To open the iSCSI Optimization Global Parameters page, click System → iSCSI Optimization→ Global Parameters in the tree view. 232 Configuring System Information
