cnfpnportcac
cnfpnportcac
Configure Port Connection Admission Control—configure CAC for a all connections on a port.
The cnfpnportcac command lets you reserve a percent of the bandwidth parameters for an individual
service type. The new configuration applies to new, incoming calls, while existing calls remain
unaffected. You can execute this command whether the port is active or in the provisioning state.
The bookfactor is the percent of utilization. It applies to connection admission control (CAC). The
booking factor does not apply to the available cell rate (AvCR) advertised by the switch to the controller.
When the default for maxbw and minbw is used for all service types, the common AvCR is advertised
for all the service types.
You must specify at least one of the optional keywords.
