iSCSI Optimization PrerequisitesThe following are iSCSI optimization prerequisites.• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Link Layer Discovery Protocol (LLDP)).• iSCSI optimization requires configuring two ingress ACL groups The ACL groups are allocated after iSCSI Optimization isconfigured.Configuring iSCSI OptimizationTo configure iSCSI optimization, use the following commands.1. For a non-DCB environment: Enable session monitoring.CONFIGURATION modecam-acl l2acl 4 ipv4acl 4 ipv6acl 0 ipv4qos 2 l2qos 1 l2pt 0 ipmacacl 0 vman-qos 0ecfmacl 0 fcoeacl 0 iscsioptacl 2NOTE: Content addressable memory (CAM) allocation is optional. If CAM is not allocated, the following features aredisabled:• session monitoring• aging• class of serviceYou can enable iSCSI even when allocated with zero (0) CAM blocks. However, if no CAM blocks are allocated, sessionmonitoring is disabled and this information the show iscsi command displays this information.2. For a non-DCB environment: Enable iSCSI.CONFIGURATION modeiscsi enable3. For a DCB environment: Configure iSCSI Optimization.EXEC Privilege modeiSCSI configuration: copy CONFIG_TEMPLATE/iSCSI_DCB_Config running-config.The configuration files are stored in the flash memory in the CONFIG_TEMPLATE file.NOTE: DCB/DCBx is enabled when you apply the iSCSI configuration in step 3. If you manually apply the iSCSIconfiguration by following steps 1 and 2, enable link layer discovery protocol (LLDP) before enabling iSCSI in step 2.You cannot disable LLDP if you enable iSCSI.4. Save the configuration on the switch.EXEC Privilege modewrite memory5. Reload the switch.EXEC Privilege modereloadAfter the switch is reloaded, DCB/ DCBx and iSCSI monitoring are enabled.6. (Optional) Configure the iSCSI target ports and optionally the IP addresses on which iSCSI communication is monitored.CONFIGURATION mode[no] iscsi target port tcp-port-1 [tcp-port-2...tcp-port-16] [ip-address address]442 iSCSI Optimization
