Table 44 Set Config port parameters (continued)

Parameter

Description

 

 

ARB_FF

Send ARB_FF (True) instead of IDLEs (False) on the loop. The default is

 

False.

 

 

InteropCredit

Interoperability credit. The number of buffer-to-buffer credits per port. 0

(External ports only)

means the default (8) is unchanged. 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.

 

 

FANEnable

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.

 

 

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. LCFEnable 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

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.

 

 

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 indefinitely. True reduces the

 

amount of arbitration on a loop when there is only one device on the

 

loop. The default is False.

 

 

PDISCPingEnable

Enables (True) or disables (False) the transmission of ping messages from

 

the switch to all devices on a loop port. The default is True.

 

 

ports [port_type]

Initiates an editing session in which to change configuration parameters for all internal ports, all external ports, or all ports based on the value given by [port_type]. port_type can be “internal” or “external”. If you omit [port_type], all ports are changed. For each parameter, enter a new value or press Enter to accept the current value shown in brackets. Press q to end the configuration. Table 44 describes the port parameters.
