cnt2XIfInDiscards
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfInDiscards
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.21
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 cnt2XIfInDiscards?
This Counter32 counts inbound packets that were deliberately discarded despite no detected errors, for example to free up buffer space, on this extended-table interface. An administrator treats sustained growth here as evidence this specific interface's receive buffering can't keep pace with the traffic it's handling. For example, cnt2XIfInDiscards rising during a burst of firmware-triggered traffic suggests buffer exhaustion on that particular port.
