Field Description
collection
method
FL_Port supports 2 frame collection methods, piling and bundling. If NL_Ports can
handle multiple frame context in a loop, using piling can minimize loop tenancies,
reduce overhead and increase loop efficiency. The modes are:
0 - piling (frames are accumulated per destination AL_PA)
1 - bundling (frames are separated in different queues based on source/destination
pairs)
The default is piling [0].
alternate
bb_credit
This is the value used in an NL_Port's FLOGI. If the value is 1, this can reduce the
loop turnaround time and increase performance. For a detail description of Alternate
BB_Credit management, refer to the FC-AL specification.
0 - An NL_Port must wait for an R_RDY before it can send a frame to the FL_Port in
a loop
1 - An NL_Port can immediately send a frame to the FL_Port without waiting for an
R_RDY
The default is [0].
open/opened
bb_credit
The maximum number of R_RDY's an FL_Port issues (provided buffers are
available) at the beginning of each loop tenancy. Configuring a higher value allows
NL_Ports to send out more frames to the Fabric in a loop and can potentially
increase performance, especially in bigger loops.
The default is [4].
send FAN
frames
Fabric Address Notification (FAN frames are sent by the Fabric to notify the public
loop devices about their node ID and address.
0 - yes, send frames
1- no, do not send frames
The default is [0].
