ifHCInUcastPkts
Module: IF-MIB
OID (symbolic): IF-MIB::ifHCInUcastPkts
OID (numeric): 1.3.6.1.2.1.31.1.1.1.7
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of packets, delivered by this sub-layer to a higher (sub-)layer, which were not addressed to a multicast or broadcast address at this sub-layer. This object is a 64-bit version of ifInUcastPkts.
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 ifHCInUcastPkts?
This 64-bit counter tallies packets delivered up from this interface's sub-layer that were addressed to a single station rather than a multicast or broadcast address, acting as the high-capacity version of ifInUcastPkts. Admins graph it alongside ifHCInOctets to see packet-rate versus byte-rate trends, which helps distinguish many small packets (e.g. VoIP) from few large ones (e.g. bulk transfer). For example, a sudden rise in ifHCInUcastPkts without a matching rise in ifHCInOctets could indicate a flood of small unicast packets, such as a SYN scan.
