What is hcxVlanIpNetbiosFiltEnbl?

This read-write true/false attribute, false by default and applicable only to 100BT and OC3 cards, filters upstream NetBIOS-over-IP packets on this VLAN, and can also be enabled per ComPort. An admin uses it to keep Windows file-sharing broadcast noise from subscriber home networks off the upstream network. For example, an admin enables this to stop NetBIOS broadcast chatter from home Windows networks from propagating upstream into the shared infrastructure.
