Description: Specifies whether IP source address filtering should be enabled on this VLAN. This filter is applicable to 100BT, and OC3 cards. It is not applicable to 10BT card. It filters traffic in the upstream direction. Default is false. This filter can also be enabled for a specific ComPort via the MIB attribute hcxStuIpSrcFiltEnable.

What is hcxVlanIpSrcFiltEnbl?

This read-write true/false attribute, false by default and applicable only to 100BT and OC3 cards, enables upstream IP source address filtering on this VLAN, and can also be enabled per ComPort. An admin turns this on to block subscribers from sending traffic with spoofed source IP addresses. For example, an admin enables source filtering on VLAN 12 to stop a customer's misconfigured router from sending upstream packets with someone else's IP address.
