1 Configure an interface or interface range to detect a connected storage device. interface ethernet node/slot/port:[subport] interface range ethernet node/slot/port:[subport]-node/slot/port[:subport] 2 Enable the interface to support a storage device that is directly connected to the port and not automatically detected by iSCSI. Use this command for storage devices that do not support LLDP. The switch auto-detects and auto-configures Dell EqualLogic storage arrays directly connected to an interface when you enable iSCSI optimization. iscsi profile-storage storage-device-name 3 Configure DCBX to use LLDP to send iSCSI application TLVs with the dot1p priorities for iSCSI traffic in INTERFACE mode. lldp tlv-select dcbxp-appln iscsi 4 Return to CONFIGURATION mode. exit 5 (Optional) If necessary, re-configure the iSCSI TCP ports and IP addresses of target storage devices in CONFIGURATION mode. Separate TCP port numbers with a comma (0-65535; default 860 and 3260). iscsi target port tcp-port1 [tcp-port2, ..., tcp-port16] [ip-address ip-address] 6 Configure the QoS policy applied to the ingress iSCSI flows. Apply the service policy to ingress interfaces in CONFIGURATION mode. (Optional) Reset the default CoS dot1p priority (default 4) and/or the trusted DCSP value used for iSCSI traffic. Assign an internal qos-group queue (0 to 7) to dot1p (0 to 7) and DSCP (0 to 63) values in POLICY-CLASS-MAP mode. class-map type application class-iscsi policy-map type application policy-iscsi class class-iscsi set qos-group traffic-class-number set cos dot1p-priority set dscp dscp-value end service-policy type application policy-iscsi 7 Enable iSCSI monitoring sessions on TCP ports in CONFIGURATION mode. iscsi session-monitoring enable 8 (Optional) Set the aging time for the length of iSCSI monitoring sessions in CONFIGURATION mode (5 to 43,200 minutes; default 10). iscsi aging time [minutes] 9 (Optional) Reconfigure the dot1p priority bits advertised in iSCSI application TLVs in CONFIGURATION mode. The default bitmap is 0x10 (dot1p 4). The default dot1p 4 value is sent in iSCSI application TLVs only if you enabled the PFC pause for dot1p 4 traffic (pfc-cos dot1p-priority command). If you do not configure an iscsi priority-bits dot1p value and you configure a set cos value in Step 6, the set cos value is sent in iSCSI application TLVs. If you configure neither the iscsi priority-bits nor the set cos value, the default dot1p 4 is advertised. iscsi priority-bits dot1p-bitmap 10 Enable iSCSI auto-detection and auto-configuration on the switch in CONFIGURATION mode. iscsi enable Configure iSCSI optimization OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# iscsi profile-storage compellent OS10(conf-if-eth1/1/1)# lldp tlv-select dcbxp-appln iscsi OS10(conf-if-eth1/1/1)# exit OS10(config)# iscsi target port 3261 ip-address 10.1.1.1 OS10(config)# policy-map type application policy-iscsi OS10(config-pmap-application)# class class-iscsi OS10 (config-pmap-c-app)# set qos-group 4 OS10 (config-pmap-c-app)# set cos 4 OS10 (config-pmap-c-app)# exit OS10(config-pmap-application)# exit OS10(config)# system qos OS10(config-sys-qos)# service-policy type application policy-iscsi 664 Converged data center services
