cnt2XIfOutDiscards

Module: CNT21-MIB

OID (symbolic): CNT21-MIB::cnt2XIfOutDiscards

OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.28

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.

What is cnt2XIfOutDiscards?

This Counter32 counts outbound packets that were deliberately discarded despite no detected errors, often to relieve buffer pressure, on this extended-table interface. An administrator treats sustained growth here as transmit-side congestion specific to that port that may need a capacity review. For example, cnt2XIfOutDiscards rising during a large file transfer suggests that interface's transmit buffers are undersized for the burst it's handling.
