Description: G.988-201210: 9.3.27 Multicast operations profile, Attribute: IGMP function. This attribute enables an IGMP function. The value 1(value 0 in G.988) specifies transparent IGMP snooping only. The value 2(value 1 in G.988) specifies snooping with proxy reporting(SPR); the value 3(value 2 in G.988) specifies IGMP proxy. The function must be consistent with the capabilities specified by the other IGMP configuration attributes.
What is gponOnuIgmpFunction?
This sets which IGMP handling mode the ONU uses for multicast: transparent snooping only, snooping with proxy reporting (SPR), or full IGMP proxy, per ITU-T G.988 9.3.27. Admins pick proxy mode to have the ONU itself terminate IGMP toward the subscriber and re-originate it upstream (reducing signaling load on the OLT), or snooping to simply forward/monitor IGMP transparently. For example, enabling proxy mode on a video service profile lets the ONU aggregate multiple set-top-box joins into fewer upstream IGMP messages.
