Addendum

• iSCSI optimization requires configuring two ingress ACL groups The ACL groups are allocated after
iSCSI Optimization is configured. (refer to When to Use CAM Profiling).
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: In FTOS Version 9.2.(0.0), 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 this information displays in the show
iscsi
command.
2. For a non-DCB environment: Enable iSCSI.
CONFIGURATION mode
iscsi enable
3. For a DCB environment: Configure iSCSI Optimization.
EXEC Privilege mode
iSCSI configuration: copy CONFIG_TEMPLATE/iSCSI_DCB_Config running-config.
The configuration files are stored in the flash memory in the CONFIG_TEMPLATE file.
NOTE: DCB/DCBx is enabled when you apply the iSCSI configuration in step 3. If you manually
apply the iSCSI configuration by following steps 1 and 2, enable link layer discovery protocol
(LLDP) before enabling iSCSI in step 2. You cannot disable LLDP if you enable iSCSI.
4. Save the configuration on the switch.
EXEC Privilege mode
write memory
5. Reload the switch.
EXEC Privilege mode
reload
After the switch is reloaded, DCB/ DCBx and iSCSI monitoring are enabled.
