iSCSI Optimization | 567
iSCSI Optimization Prerequisites
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Chapter 30,
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).
Step Task Command Command Mode
1 For a non-DCB environment: Enable session
monitoring.
Configuring fcoeacl and iscioptacl are optional in
FTOS version 9.1.(0.0).
For a DCB environment: Configure iSCSI
Optimization. The configuration files are stored in the
flash memory in the CONFIG_TEMPLATE.
Note: DCB/DCBx is enabled when the iSCSI
configuration is applied.
For OpenFlow: Allocate CAM space.
