Default iSCSI Optimization Values
Table 24-1 shows the default values for the iSCSI optimization feature.
iSCSI Optimization Prerequisites
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Chapter 29,
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:
Table 24-1. iSCSI Optimization: Default Parameters
Parameter Default Value
iSCSI Optimization global setting Enabled
iSCSI CoS mode (802.1p priority queue
mapping)
Enabled: dot1p priority 4 without remark setting
iSCSI CoS Packet classification iSCSI packets are classified by VLAN instead of by DSCP values.
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.
Step Task Command Command Mode
1 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.
iSCSI configuration:
copy flash:/
