Table 14-16. Port Configuration Parameters (Continued)
Parameter
Automatic performance tuning for FL_Ports only. The default
is True.
Link control frame preference routing. This parameter
appears only if AutoPerfTuning is False. Enables (True) or
disables (False) preferred routing of frames with R_CTL =
1100 (Class 2 responses). The default is False. Enabling
LCFEnable will disable MFSEnable.
Multi-Frame Sequence bundling. This parameter appears
only if AutoPerfTuning is False. Prevents (True) or allows
(False) the interleaving of frames in a sequence. The default
is false. Enabling MFSEnable disables LCFEnable
and VIEnable.
Virtual Interface (VI) preference routing. This parameter
appears only if AutoPerfTuning is False. Enables (True) or
disables (False) VI preference routing. The default is False.
Enabling VIEnable will disable MFSEnable.
Management server enable. Enables (True) or disables
(False) management server on this port. The default is True.
Loop circuit closure prevention. Enables (True) or disables
(False) the loop's ability to remain in the open state indefi-
nitely. True reduces the amount of arbitration on a loop when
there is only one device on the loop. The default is False.
I/O Stream Guard. Enables or disables the suppression of
RSCN messages. IOStreamGuard can have the following
values:
Description
If AutoPerfTuning is enabled (True) and the port is an
FL_Port, MFSEnable is automatically enabled. LCFEn-
able and VIEnable are overridden to False.
If AutoPerfTuning is disabled (False), MFSEnable,
LCFEnable, and VIEnable retain their original values.
Enable – Suppresses the reception of RSCN messages
from other ports for which IOStreamGuard is enabled.
Disable – Allows free transmission and reception of
RSCN messages.
Auto – Suppresses the reception of RSCN messages
when the port is connected to an initiator device with a
QLogic HBA. For older QLogic HBAs, such as the
QLA2200, the DeviceScanEnabled parameter must also
be enabled. The default is Auto.
