Syntax
LowBBCreditThresh lowBBcreditThreshold
Purpose
This command configures the low BB_credit threshold of the OpenTrunking
configuration. The low BB_credit threshold is defined 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.
Parameters
This command has one parameter:
Command Example
Root> perf openTrunking creditStarvThresh 20
perf.openTrunking.lowBBCreditThresh
lowBBcreditThreshold Specifies the credit starvation threshold in
terms of a percentage. Valid values are
integers in the range 1 to 99 or default.
Specifying the value default sets the
parameter to the default threshold level of
10%.
