Default iSCSI Optimization Values
Table 25-1 shows the default values for the iSCSI optimization feature.
iSCSI Optimization Prerequisites
• iSCSI optimization requires LLDP to be enabled on the switch. LLDP is enabled by default, but is
disabled when you enable PFC (see Enabling LLDP).
• iSCSI optimization requires two ingress ACL groups to be allocated in CAM (see CAM Allocation).
Tip: Before you configure iSCSI optimization, you can ensure that these prerequisites are met by copying
the iSCSI configuration file to the running configuration. The iSCSI configuration file is stored at:
flash:/CONFIG_TEMPLATE/ISCSI_DCB_CONFIG.
