iSCSI Optimization | 481
iSCSI Optimization Prerequisites
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Chapter 28,
Link Layer Discovery Protocol (LLDP)).
• iSCSI optimization requires two ingress ACL groups to be configured. The ACL groups are allocated
after iSCSI Optimization is configured. (refer to When to Use CAM Profiling).
Configuring iSCSI Optimization
To configure iSCSI optimization on a switch, follow these steps:
VLAN priority tag iSCSI flows are assigned by default to dot1p priority 4 without remark
setting.
DSCP None: user-configurable.
Remark Not configured.
iSCSI session aging time 10 minutes
iSCSI optimization target ports iSCSI well-known ports 3260 and 860 are configured as default (with no IP
address or name) but can be removed as any other configured target.
iSCSI session monitoring Disabled. The CAM allocation for iSCSI is set to zero (0).

For non-DCB environment: Enable session
monitoring.
For DCB environment: Configure iSCSI
Optimization. The configuration files are stored
in the flash memory in the
CONFIG_TEMPLATE file.
Note: DCB/DCBx will be enabled when the iSCSI
configuration is applied.
