What is hcxVlanL2Ipv4FiltEnbl?
This read-write true/false attribute, false by default and applicable only to 100BT and OC3 cards, filters IPv4 packets in both directions on this VLAN, and can also be enabled per ComPort. An admin can use this to fully block IPv4 traffic on a VLAN dedicated to a different protocol. For example, an admin enables this on a VLAN reserved for non-IP legacy traffic to strip out any stray IPv4 packets that appear.
