This Gauge32 counts standard Ethernet-II encoded packets filtered by the STU during the current, still-accumulating 15-minute period. Because ordinary Ethernet-II is the dominant frame type on a subscriber LAN, a nonzero or growing value here means everyday host traffic is being actively blocked rather than merely idle, which is worth investigating if the customer reports no connectivity. For instance, if a subscriber's filter policy on this STU rejects Ethernet-II frames outright, this counter will tick up every time their PC tries to reach the network during the current window.
