perf
as the percentage of time that no transmit BB_Credits are passed on
the link. When the threshold value is exceeded, the system tries to
reroute the flows that are going to the ISL with the problem.
Effectively, the threshold is the percent of the time that the port does
not receive BB_Credits before traffic is rerouted away from the port.
This threshold is also used for prevention of improperly rerouting to
an ISL that lacks BB_Credits. In other words, the system does not
reroute a flow to a link that lacks BB_Credits even if that link is
significantly under its loading threshold. The system tries to reroute
traffic away from a link that lacks BB_Credits, even if the loading
threshold is significantly below the limit.
