Reports the cumulative total bytes this specific Virtual System's policy silently dropped. Comparing this against vsxCountersBytesAcceptedTotal for the same tenant shows what fraction of that customer's traffic volume, by bandwidth rather than packet count, is being discarded, which matters when a small number of large dropped flows could represent significant wasted bandwidth even if the packet-count drop rate looks modest. Example: a tenant with a low vsxCountersDroppedTotal packet count but a disproportionately high vsxCountersBytesDroppedTotal is losing a few large flows rather than many small ones, worth investigating as a specific blocked bulk-transfer attempt.
