ifHCOutMulticastPkts
Module: IF-MIB
OID (symbolic): IF-MIB::ifHCOutMulticastPkts
OID (numeric): 1.3.6.1.2.1.31.1.1.1.12
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The total number of packets that higher-level protocols requested be transmitted, and which were addressed to a multicast address at this sub-layer, including those that were discarded or not sent. For a MAC layer protocol, this includes both Group and Functional addresses. This object is a 64-bit version of ifOutMulticastPkts.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is ifHCOutMulticastPkts?
This 64-bit counter tracks the total number of multicast and broadcast packets that the network interface has transmitted, including both successfully sent and discarded packets. It provides high-capacity counting (up to 18 quintillion) for interfaces that need to measure multicast traffic at higher speeds than the 32-bit version allows. Network operators use this metric to monitor multicast group participation and validate that broadcast traffic is properly flowing out of the interface.
