cnt2XIfOutBroadcastPkts
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfOutBroadcastPkts
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.27
Node type: OBJECT-TYPE
Type: Counter32
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.
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 cnt2XIfOutBroadcastPkts?
This Counter32 counts packets that higher-layer protocols requested be transmitted addressed to the broadcast address at this sublayer, including ones discarded or never sent, with discontinuities tied to the interface's counter-discontinuity timestamp. An administrator watches for abnormal broadcast egress volume here as a sign a specific attached device is flooding the segment with broadcasts. For example, cnt2XIfOutBroadcastPkts spiking on one interface while others stay flat points to a device behind that particular port generating excess broadcast traffic.
