Table 34 Port configuration parameters (continued) Parameter ARB_FF InteropCredit FANEnable AutoPerfTuning LCFEnable MFSEnable VIEnable MSEnable NoClose IOStreamGuard PDISCPingEnable Description Send ARB_FF (True) instead of IDLEs (False) on the loop. The default is False. Interoperability credit. The number of buffer-to-buffer credits per port. 0 means the default is unchanged. Default buffer-to-buffer credits are 16 per port. Changing interoperability credits is necessary only for E_Ports that are connected to non-FC-SW-2-compliant switches. Contact your authorized maintenance provider for assistance in using this feature. Fabric address notification. Enables (True) or disables (False) the communication of the FL_Port address, port name, and node name to the logged-in NL_Port. The default is True. 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. LCFEnable and VIEnable are overridden to False. • If AutoPerfTuning is disabled (False), MFSEnable, LCFEnable, and VIEnable retain their original values. 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 indefinitely. True reduces the amount of arbitration on a loop when there is only one device on the loop. The default is False. 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. Enables (True) or disables (False) the transmission of ping messages from the switch to all devices on a loop port. The default is True. 8/20q Fibre Channel Switch command line interface guide 197
