4. When you finish, choose OK to send the values you entered to the selected switch.

b. To determine the ranges you should configure, monitor the VBR traffic on
your network, then group your VBR circuits into appropriate SCR ranges.
c. In the Scale Factor (%) column, enter a scale factor percentage to use when
computing bandwidth requirements for circuits in each of the SCR ranges you
defined.
For example, if you enter a value of 125%, a circuit with an SCR of
12,000 CPS would be allocated a bandwidth of 15,000 CPS (assuming you
did not define physical port scale factors).
d. In the Maximum MBS column, enter an MBS value that defines the MBS
value allowed for each range of SCR values.
For example, if you enter an MBS value of 256 for the range of SCR values
(0-10000), a circuit with an SCR of 7,000 CPS and MBS of 300 cells is
rejected by the CAC function because its MBS exceeds the specified
maximum MBS.
You will need to perform a PRAM Sync for the CAC to be updated in the switch
configuration.
