Adjusting the CAC
Configuring the CAC
Note – Keep in mind that since both the CDV and CLR calculations are non-linear
in nature, the resulting equivalent bandwidth for VBR-RT and VBR-NRT circuits
may not be the same as it was in previous releases. Since the circuits might end up
with a larger equivalent bandwidth as a result of the CDV objectives, one or more
existing circuits many no longer be admitted because of insufficient bandwidth on a
port where they were previously admitted.
4. In the Alpha column, specify the fraction of the CBR (or VBR-RT) cells that can
5. When you finish, choose OK to send the values you entered to the selected switch.
A-61/19/05
exceed this CDV objective. This value is a negative power of ten (1.0e–). By
default, the Alpha field for each of the CBR and VBR Real Time classes is set to 7
(1 in 10,000,000).
You will need to perform a PRAM Sync for the CAC to be updated in the switch
configuration.
