Default Iscsi Optimization Values - Dell S4820T Configuration Manual

iSCSI optimization, which can turn on flow control again on reboot, use the no iscsi enable
command and save the configuration.
When you enable iSCSI on the switch, the following actions occur:
• Link-level flow control is globally enabled, if it is not already enabled, and PFC is disabled.
• iSCSI session snooping is enabled.
• iSCSI LLDP monitoring starts to automatically detect EqualLogic arrays.
The following message displays when you enable iSCSI on a switch and describes the configuration
changes that are automatically performed:
%STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_ENABLE: iSCSI has been enabled causing flow
control to be
enabled on all interfaces. EQL detection and enabling iscsi profile-compellent
on an interface
may cause some automatic configurations to occur like jumbo frames on all ports
and no storm
control and spanning tree port-fast on the port of detection.
You can reconfigure any of the auto-provisioned configuration settings that result when you enable iSCSI
on a switch.
When you disable the iSCSI feature, iSCSI resources are released and the detection of EqualLogic arrays
using LLDP is disabled. Disabling iSCSI does not remove the MTU, flow control, portfast, or storm control
configuration applied as a result of enabling iSCSI.
NOTE: By default, CAM allocation for iSCSI is set to 0. This disables session monitoring.
