cnt2IfInDiscards
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2IfInDiscards
OID (numeric): 1.3.6.1.4.1.333.2.1.2.2.1.14
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.
What is cnt2IfInDiscards?
This Counter32 counts inbound packets that were deliberately discarded even though no errors were detected, for example to free up buffer space. An administrator treats a rising count as a sign that this interface's receive buffers are being overwhelmed by incoming traffic. For example, cnt2IfInDiscards climbing steadily during peak business hours suggests this port's receive buffering is undersized for the current load.
