dvbNiuMulticast
Module: DVB-CABLE-NIU-MIB
OID (symbolic): DVB-CABLE-NIU-MIB::dvbNiuMulticast
OID (numeric): 1.3.6.1.3.110.1.1.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object is used to restrict the level of multicast support provided by the NIU. disabled - No IGMP or multicast packets are forwarded through the NIU in either direction. downstreamOnly - Only multicast packets in the downstream direction will be forwarded for the group to which the subscriber has membership. IGMP messages are allowed to manage group membership for downstream groups only. Any upstream multicast packets are discarded. upstreamOnly - Only multicast packets in the upstream direction will be forwarded by the NIU. IGMP messages are allowed to manage group membership for upstream groups only. enabled - Multicast forwarding in the downstream and upstream direction is allowed. IGMP messages are allowed to manage group membership for both upstream and downstream multicast groups.
What is dvbNiuMulticast?
Controls how much IGMP/multicast traffic the NIU forwards between the cable (HFC) side and the subscriber side: disabled blocks all multicast and IGMP, downstreamOnly/upstreamOnly restrict forwarding and IGMP handling to one direction, and enabled allows full two-way multicast. An admin deploying a typical video-only residential service would commonly set this to downstreamOnly.
