preRsvdMandatoryBandwidth The value of preRsvdMandatoryBandwidth specifies the bandwidth pre-reserved for all the mandatory channels on a given interface in kilo-bits per second(kbps). If the value of unconstrainedBandwidth is '0', no mandatory channels are allowed. If the value of unconstrainedBandwidth is '-1', then all mandatory and optional channels are allowed. If the value of preRsvdMandatoryBandwidth is equal to the value of unconstrainedBandwidth, then all the unconstrained bandwidth on a given interface is allocated to mandatory channels configured through multicast cac policy on that interface and no optional groups (channels) are allowed. The default value of '-1' can be set only by setting unconstrainedBandwidth object to '-1'. An attempt to set the value of preRsvdMandatoryBandwidth to '-1' will result in inconsistent value error. The value of preRsvdMandatoryBandwidth will be set to the same as unconstrainedBandwidth if the latter is set to either '-1' or '0'. The value of preRsvdMandatoryBandwidth should always be less than or equal to that of unconstrainedBandwidth. An attempt to set the value of preRsvdMandatoryBandwidth greater than that of unconstrainedBandwidth will result in inconsistent value error.
