cell in the shaper table that you want to change.
To set a new Sustainable Cell Rate or Peak Cell Rate shaper, enter the new value

in the bits/second (bps) column. The system automatically calculates the
cells/second (cps) based on the value you enter.
To set a new Maximum Burst Size shaper, enter the new value in the cells
n
column. The system automatically calculates the bits based on the value you
enter.
How you configure the input shapers depends on the type of service you have.
If you have a peak rate service:
n
Set the peak rate at the maximum allowable value.
n
Set the sustained cell rate at the same rate as the peak rate.
n
If you have a sustained rate service:
n
Set the peak rate at the line rate (for example 45Mbps for a DS3 line).
n
Set the sustained cell rate and maximum burst rate at the values given to
n
you by your service provider.
