ifHCOutBroadcastPkts
Module: IF-MIB
OID (symbolic): IF-MIB::ifHCOutBroadcastPkts
OID (numeric): 1.3.6.1.2.1.31.1.1.1.13
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 broadcast address at this sub-layer, including those that were discarded or not sent. This object is a 64-bit version of ifOutBroadcastPkts.
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 ifHCOutBroadcastPkts?
This 64-bit counter counts packets that higher-layer protocols asked to be sent to a broadcast address on this interface, including ones that were ultimately discarded or never transmitted, as the high-capacity version of ifOutBroadcastPkts. Admins watch it because an unusually high or fast-growing value often points to a broadcast storm or misconfigured ARP/DHCP flooding on the segment. For example, ifHCOutBroadcastPkts climbing by tens of thousands per second on an access-layer switch port would prompt an admin to check for a bridging loop.
