Reports the cumulative total bytes this specific Virtual System's policy explicitly rejected. As the byte-volume counterpart to vsxCountersRejectedTotal, this shows the bandwidth cost of actively refused connections for that one tenant, useful when assessing whether rejected traffic is meaningfully consuming that tenant's share of chassis bandwidth even though it never reaches its destination. Example: a tenant whose vsxCountersBytesRejectedTotal is unexpectedly large relative to its accepted bytes may be absorbing a sizeable volumetric attack that's being rejected rather than silently dropped.
