Description: Specifies whether ARP authentication filtering should be enabled for this ComPort. This filter is applicable to 10BT, 100BT, and OC3 cards. It filters traffic in the upstream direction. Default is false. This filter can also be enabled for an entire VLAN via the MIB attribute hcxVlanIpArpFiltEnbl.
What is hcxStuIpArpFiltEnable?
This read-write true/false object enables ARP authentication filtering for upstream traffic from this ComPort, applicable to 10BT, 100BT, and OC3 cards and defaulting to false, per the description, and notes it can also be enabled at the whole-VLAN level. An admin enables this on a specific device to block spoofed or unauthorized ARP traffic from that subscriber. For example, an admin enables hcxStuIpArpFiltEnable on a single suspicious ComPort suspected of ARP spoofing rather than affecting the whole VLAN.
