What is hcxStuL2CurrIpv6FiltStat?
This Gauge32 counts IPv6 packets filtered by the STU during the current 15-minute period. On this cable-headend platform IPv6 filtering being active is notable because it means any dual-stack subscriber device attempting IPv6 connectivity is being silently blocked at the STU rather than merely unsupported upstream. For example, a subscriber's modern OS auto-configuring IPv6 alongside IPv4 would generate filtered packets counted here even while their IPv4 service works fine.
