M4300 Intelligent Edge Series Fully Managed Stackable Switches Default Format Mode 10 minutes iscsi aging time time Global Config Parameter Description time The number of minutes a session must be inactive prior to its removal. Range: 1-43,200. Command example: The following example sets the aging time for iSCSI sessions to 100 minutes: (NETGEAR Switch)(config)#iscsi aging time 100 no iscsi aging time Use the no iscsi aging time command to reset the aging time value to the default value. Format Mode no iscsi aging time Global Config iscsi cos This command sets the quality of service profile that will be applied to iSCSI flows. iSCSI flows are assigned by default to the highest VPT or DSCP mapped to the highest queue not used for switch management. Take care that you configure the relevant Class of Service parameters for the queue in order to complete the setting. Setting the VPT or DSCP sets the QoS profile which determines the egress queue to which the frame is mapped. The switch default setting for egress queues scheduling is Weighted Round Robin (WRR). You can complete the QoS setting by configuring the relevant ports to work in other scheduling and queue management modes via the Class of Service settings. Depending on the platform, these choices may include strict priority for the queue used for iSCSI traffic. The downside of strict priority is that, in certain circumstances (under heavy high priority traffic), other lower priority traffic may get starved. In WRR the queue to which the flow is assigned to can be set to get the required percentage. iSCSI optimization is best applied to mixed-traffic networks in which iSCSI packets constitute a portion of overall traffic. In these cases, the assignment of iSCSI packets to nondefault queues can provide flows with lower latency and prevent queue resource contention. If iSCSI frames comprise most of the traffic passing through the switch, the system provides optimal throughput if all traffic is assigned to the default queue. An example of this situation is a Storage Area Network (SAN) in which the switch is dedicated to interconnecting iSCSI Quality of Service Commands 998 CLI Command Reference Manual

Quality of Service Commands

CLI Command Reference Manual

998

Command example:

The following example sets the aging time for iSCSI sessions to 100 minutes:

(NETGEAR Switch)(config)#iscsi aging time 100

no iscsi aging time

Use the

no iscsi aging time

command to reset the aging time value to the default

value.

iscsi cos

This command sets the quality of service profile that will be applied to iSCSI flows. iSCSI

flows are assigned by default to the highest VPT or DSCP mapped to the highest queue not

used for switch management. Take care that you configure the relevant Class of Service

parameters for the queue in order to complete the setting.

Setting the VPT or DSCP sets the QoS profile which determines the egress queue to which

the frame is mapped. The switch default setting for egress queues scheduling is Weighted

Round Robin (WRR).

You can complete the QoS setting by configuring the relevant ports to work in other

scheduling and queue management modes via the Class of Service settings. Depending on

the platform, these choices may include strict priority for the queue used for iSCSI traffic. The

downside of strict priority is that, in certain circumstances (under heavy high priority traffic),

other lower priority traffic may get starved. In WRR the queue to which the flow is assigned to

can be set to get the required percentage.

iSCSI optimization is best applied to mixed-traffic networks in which iSCSI packets constitute

a portion of overall traffic. In these cases, the assignment of iSCSI packets to nondefault

queues can provide flows with lower latency and prevent queue resource contention.

If iSCSI frames comprise most of the traffic passing through the switch, the system provides

optimal throughput if all traffic is assigned to the default queue. An example of this situation is

a Storage Area Network (SAN) in which the switch is dedicated to interconnecting iSCSI
