Send FAN frames?
Specifies whether fabric address notification (FAN) frames are sent to public loop devices to
notify them of their node ID and address. When set to
1
, such frames are sent; when set to 0,
such frames are not sent.
Always send RSCN?
Following the completion of loop initialization, a remote state change notification (RSCN) is
issued only when FL_Ports detect the presence of new devices or the absence of preexisting
devices. When this feature is set, an RSCN always is issued following the completion of loop
initialization, regardless of the presence or absence of new or preexisting devices.
Enable CLOSE on OPEN Received?
There are compatibility issues between tachLite-based products and switches with Enable
CLOSE on OPEN Received. Multiple options are introduced to work around this issue and
there is a known Open Deadlock defect, which has become part of legacy code. Preferred
default is 4. See
Table 18 for possible values. Each field is described after the table.
Do Not Allow AL_PA 0x00?
Some loop devices do not operate well with AL_PA 0 on the same loop. This option provides
a workaround for such devices. By default, the switch can use a phantom AL_PA 0 for an
embedded port in a QuickLoop configuration. When set to 1, the switch does not use
AL_PA 0.
Initialize All Looplets?
By default, only looplets in the same zone are reinitialized. When set to 1, the option forces a
reinitialization of all the looplets in the QuickLoop.
System Services Settings
