Description: Specifies whether BOOTP requests, or DHCPDISCOVER, or DHCPREQUEST, or DHCPRELEASE packets should be filtered on this VLAN. This filter is applicable to 100BT, and OC3 cards. It is not applicable to 10BT card. It filters traffic in the downstream direction. Default is true. This filter cannot be controlled per ComPort.
What is hcxVlanIpBootpReqFiltEnbl?
This read-write true/false attribute, true by default and applicable only to 100BT and OC3 cards, filters BOOTP, DHCPDISCOVER, DHCPREQUEST, or DHCPRELEASE packets in the downstream direction on this VLAN, and unlike some sibling filters cannot be controlled per ComPort. An admin relies on this default-on filter to keep unwanted DHCP/BOOTP request broadcasts from flooding every modem on the VLAN. For example, an admin leaves this at its default of true to prevent unwanted BOOTP or DHCP request broadcasts from reaching every subscriber modem on the VLAN.
