cnt2IfInNUcastPkts
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2IfInNUcastPkts
OID (numeric): 1.3.6.1.4.1.333.2.1.2.2.1.13
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of non-unicast (i.e., subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.
What is cnt2IfInNUcastPkts?
This Counter32 counts non-unicast, meaning subnetwork-broadcast or subnetwork-multicast, packets delivered up to a higher-layer protocol on this interface. An administrator watches for abnormal spikes here as an early sign of a broadcast storm reaching that particular segment. For example, cnt2IfInNUcastPkts climbing far faster than usual on slot 3's interface would point to a broadcast storm entering through that specific port.
