Iscsi Optimization Prerequisites; Configuring Iscsi Optimization - Dell S4048–ON Configuration Manual

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 this information the show iscsi command displays this information.
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.
6. (Optional) Configure the iSCSI target ports and optionally the IP addresses on which iSCSI communication is monitored.
CONFIGURATION mode
[no] iscsi target port tcp-port-1 [tcp-port-2...tcp-port-16] [ip-address address]
