The CAM allocation for iSCSI is set tozero (0).iSCSI Optimization PrerequisitesThe following are iSCSI optimization prerequisites.• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Link LayerDiscovery Protocol (LLDP)).• iSCSI optimization requires configuring two ingress ACL groups The ACL groups are allocated afteriSCSI Optimization is configured.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 0vman-qos 0 ecfmacl 0 fcoeacl 0 iscsioptacl 2NOTE: Content addressable memory (CAM) allocation is optional. If CAM is not allocated, thefollowing features are disabled:• session monitoring• aging• class of serviceYou can enable iSCSI even when allocated with zero (0) CAM blocks. However, if no CAMblocks are allocated, session monitoring is disabled and this information the show iscsicommand 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 manuallyapply the iSCSI configuration 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.466 iSCSI Optimization
