Description
Select the switch's unit ID that will be used here.
Select the switch's port range that will be used here.
Select the queue ID that the Congestion Point (CP) is attached to here.
The relation between the queue ID and CP is one-to-one. The CP is
specified by the queue ID to which the CP is attached to. The range is
from 0 to 7. Select the None option to use the default settings on the
specified port(s).
Enter the minimum number of octets to be returned in a CNM from the
data frame that triggered transmission of the CNM here. The range is
from 0 to 64. By default, this value is 0.
Enter the minimum number of octets to queue in the CP's queue
between transmissions of CNMs here. The range is from 10000 to
4294967295 octets. By default, this value is 15000 octets.
Enter the set point value (cpQSp) in octets for the queue managed by
this CP here. Congestion Notification Messages are transmitted to the
sources of the frames queued in this CP's queue in order to keep the
total number of octets stored in the queue at this set point. The range
is from 100 to 4294967295 octets. By default, this value is 26000
octets.
Enter the weight change in the queue length in the calculation of the
cpFb which is used to determine the value of the Quantized Feedback
here. The weight cpW is equal to two to the power of this value. Thus,
setting the variable to -1, means the cpW is equal to a half. The range
is from -10 to 10. By default, this value is 2 to the power of 1.
