Parameter Default Value
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).
iSCSI Optimization Prerequisites
The following are iSCSI optimization prerequisites.
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to Link Layer Discovery Protocol (LLDP)).
• 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 3 ipv4acl 4 ipv6acl 0 ipv4qos 2 l2qos 1 l2pt 0 ipmacacl 0 vman-qos 0 ecfmacl 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.
CONFIGURATION mode
iscsi enable
3 Configure DCB and 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]
