13 – Command Reference Set Config Port
Table 13-14.  Port Configuration Parameters (Continued)
Parameter | Description  | 
  | 
  | 
AutoPerfTuning  | Automatic performance tuning for FL_Ports only. The default  | 
  | is True.  | 
  |  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.  | 
LCFEnable  | 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.  | 
MFSEnable  | |
  | 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.  | 
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.  | 
MSEnable  | Management server enable. Enables (True) or disables  | 
  | (False) management server on this port. The default is True.  | 
NoClose  | 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.  | 
IOStreamGuard  | I/O Stream Guard. Enables or disables the suppression of  | 
  | RSCN messages. IOStreamGuard can have the following  | 
  | 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.  |
