Description: G.988-201210: 9.3.27 Multicast operations profile, Attribute: Upstream IGMP rate. This attribute limits the maximum rate of upstream IGMP traffic. Traffic in excess of this limit is silently discarded. The attribute value is specified in messages/second. The recommended default value 0 imposes no rate limit on this traffic.
What is gponOnuIgmpUpstreamProtoRate?
This limits the maximum rate of upstream IGMP traffic, in messages per second, with excess traffic silently discarded; a value of 0 (the recommended default) imposes no rate limit, per ITU-T G.988 9.3.27. Admins lower it to protect the OLT's control plane from a misbehaving or compromised subscriber device flooding IGMP join/leave messages. For example, capping this rate stops a malfunctioning set-top box from overwhelming the OLT with rapid channel-change requests.
