When Changes Take Effect
Changes to this file take effect when the associated physical port is updated by one of
the methods described under
When Changes Take Effect at the Port on page 8-5 earlier
in this chapter. A change can be implemented on line by exiting the record (
[F3]
), then
opening the associated physical Port record and pressing
[F7]
to update the port.
1 Some formulae that might help in determining these values are:
B
C
>= 8 times maximum packet size.
B
E
<= B
C
multiplied by [(line speed/CIR) minus 1].
Committed Information Rate
(CIR) is the data throughput rate that the network agrees to support under normal con-
ditions.
Committed Burst Size
(B
C
) is the maximum amount of data that the network agrees to transfer under normal
conditions within the time period defined by B
C
/CIR. Any data exceeding this value
