If transmit PHY rate between all pairs of MoCA nodes are greater than or equal to 'mocaIfPhyThreshold', then transmit PHY rate of one pair of MoCA node is less than 'mocaIfPhyThreshold', send this notification if 'mocaIfPhyThresholdEnable' is 'true'. This notification sends the lowest PHY rate in the MoCA network, or 'mocaMeshTxRate', which is the transmit PHY rate from the node specified with 'mocaMeshTxNodeIndex', to the node specified with 'mocaMeshRxNodeIndex'. If multiple links have the same lowest PHY rate, sends the PHY rate for the link with the lowest 'mocaMeshTxNodeIndex'. If multiple links with the same 'mocaMeshTxNodeIndex' have the same lowest PHY rate, sends the PHY rate for the link with the lowest 'mocaMeshRxNodeIndex'. Network management system should access 'mocaMeshTable' to find if there are additional links below the threshold bandwidth. For example, MoCA interface with 'ifIndex' 1 detects transmit PHY rate from 'mocaMeshTxNodeIndex' 2 to 'mocaMeshRxNodeIndex' 4 is 150 Mbps, and this link is the first link to drop below the 'mocaIfPhyThreshold', then this trap contains one variable binding of mocaMeshTxRate.1.2.4 = 150
