What is hcxStuL2Ipv4FiltEnbl?
This read-write true/false object filters IPv4 packets for this ComPort in both directions, applicable to 100BT and OC3 but not 10BT, defaulting to false, per the description, and can also be set per-VLAN. An admin enables this to block all IPv4 traffic to and from a specific subscriber device, for example while investigating a suspected compromise. For example, an admin enables hcxStuL2Ipv4FiltEnbl temporarily to isolate a ComPort during an active security incident.
