What is hcxStuIpBootpReplyFiltEnbl?
This read-write true/false object filters BOOTP replies, DHCPOFFER, or DHCPACK packets for this ComPort, 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 prevent a subscriber's device from acting as a rogue DHCP server answering other customers' requests. For example, an admin enables hcxStuIpBootpReplyFiltEnbl on a ComPort discovered to be handing out its own DHCPOFFERs to neighboring subscribers.
