This reports the CFM frame budget specifically allocated to hardware slot 6, as stated plainly in its description, another entry in the identical per-slot budget series covering the full range of chassis slots. An admin checks this the same way as the other slot fields, as the specific capacity ceiling relevant only to services hosted on slot 6's card. For example, on a large multi-slot chassis, an admin auditing CFM capacity across the whole system would tabulate cienaCesCfmGlobalFrameBudgetSlot6 alongside every other slot's value to identify which single slot has the least remaining headroom for new services.
