5. Set the Low BB Credit Threshold.
NOTE: Earlier versions of this dialog box may display Credit Starvation
Threshold instead of Low BB Credit Threshold.
NOTE: Using default settings for this threshold should work well in
most cases. This step is not required.
This is the percentage of time that the transmitting link cannot
transmit because BB_Credit is unavailable. It is the percent of
time that the link can be treated as “back-pressured” by the
rerouting algorithm. This value is also used when determining
routes for a transmit link. A back-pressured ISL cannot be the
recipient of traffic rerouted from other ISLs, and traffic on a
back-pressured ISL may be rerouted even if the ISL is not
congested.
