iSCSI session monitoring

iSCSI Optimization Prerequisites

The following are iSCSI optimization prerequisites.
• iSCSI optimization requires LLDP on the switch. LLDP is enabled by default (refer to
Discovery Protocol
• 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 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.
iSCSI Optimization
(LLDP)).
Default Value
Disabled. The CAM allocation for iSCSI is set to
zero (0).
