Module: NSCRTV-FTTX-GPON-MIB
OID (symbolic): NSCRTV-FTTX-GPON-MIB::gponOnuIgmpDownstreamTCI
OID (numeric): 1.3.6.1.4.1.17409.2.8.6.4.1.1.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-create
Description: G.988-201210: 9.3.27 Multicast operations profile, Attribute: Downstream IGMP and multicast TCI(last two bytes). Under control of gponOnuIgmpDownstreamTagControl(first byte of Downstream IGMP and multicast TCI attribute), the downstream IGMP TCI attribute defines a VLAN ID and P-bits to add to both the IGMP/MLD and multicast frames.
What is gponOnuIgmpDownstreamTCI?
This defines the VLAN ID and P-bits (the last two bytes of the downstream IGMP-and-multicast TCI attribute) added to downstream IGMP/MLD and multicast frames, active when gponOnuIgmpDownstreamTagControl calls for tagging, per ITU-T G.988 9.3.27. Admins set it so multicast video traffic delivered to the subscriber carries the correct VLAN tag expected by the subscriber's CPE/set-top box. For example, this ensures downstream video frames are tagged onto the correct customer-facing VLAN before delivery.
