iSCSI Optimization Prerequisites

The following are iSCSI optimization prerequisites.
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to
• iSCSI optimization requires configuring two ingress ACL groups The ACL groups are allocated after iSCSI Optimization is
configured.

Configuring iSCSI Optimization

To configure iSCSI optimization, use the following commands.
1 For a non-DCB environment: Enable session monitoring.
CONFIGURATION mode
cam-acl l2acl 4 ipv4acl 4 ipv6acl 0 ipv4qos 2 l2qos 1 l2pt 0 ipmacacl 0 vman-qos 0 ecfmacl 0
fcoeacl 0 iscsioptacl 2
NOTE: Content addressable memory (CAM) allocation is optional. If CAM is not allocated, the following features are
disabled:
• session monitoring
• aging
• class of service
You can enable iSCSI even when allocated with zero (0) CAM blocks. However, if no CAM blocks are allocated, session
monitoring is disabled and the show iscsi command displays this information.
2 For a non-DCB environment: Enable iSCSI.
Default Value
Disabled.
dot1p priority 4 without the remark setting when you enable
iSCSI. If you do not enable iSCSI, this feature is disabled.
When you enable iSCSI, iSCSI packets are queued based on
dot1p, instead of DSCP values.
iSCSI flows are assigned by default to dot1p priority 4 without
the remark setting.
