DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide iSCSI The iSCSI awareness application involved in providing automated QoS preferential treatment of iSCSI flows can be divided into the following categories: Detecting the establishment and termination of iSCSI sessions and connections by snooping packets used in the iSCSI protocol. Maintaining a database of currently active iSCSI sessions and connections to store data about the participants. This allows the formulation of classifier rules giving the data packets for the session the desired QoS treatment. Installing and removing classifier rule sets as needed for the iSCSI session traffic. Monitoring activity in the iSCSI sessions to allow for aging out session entries if the session termination packets are not received. iSCSI Settings This window is used to display and configure the Internet Small Computer Systems Interface (iSCSI) settings. To view the following window, click QoS > iSCSI > iSCSI Settings, as shown below: Figure 7-29 iSCSI Settings Window The fields that can be configured are described below: Parameter iSCSI State iSCSI CoS Session Aging Time Description Select to globally enable or disable the iSCSI awareness feature here. Select the iSCSI CoS that will be configured here. Options to choose from are: VPT - Specifies to use VLAN Priority Tag (VPT) to assign iSCSI session packets. Enter the VPT value in the space provided. DSCP - Specifies to use DSCP to assign iSCSI session packets. Enter the DSCP value in the space provided. Default - Specifies to use the default settings. By default, the VPT is used with the value of 7. Select the Remark option to mark the iSCSI frames with the configured VPT or DSCP when egressing the Switch. Enter the session aging time value here. The range is from 1 to 43200 minutes. This is used to configure the aging time for iSCSI sessions. When configuring the aging time to be longer than the current setting, the current sessions will be timed out and use the new aging time. When configuring the aging time to be shorter than the current setting, sessions that are longer than the new aging time will be deleted, and sessions that are shorter than or equal to the new aging time will be continue to be monitored with the new setting. Select the Default option to use the default value which is 5 minutes. 444
