ifOutDiscards
Module: IF-MIB
OID (symbolic): IF-MIB::ifOutDiscards
OID (numeric): 1.3.6.1.2.1.2.2.1.19
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.
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 ifOutDiscards?
This counter tracks the number of outbound packets intentionally dropped by the interface, even though they contained no transmission errors. Common reasons for discards include buffer exhaustion, rate limiting, or access control. Network operators monitor this metric to detect congestion, queueing problems, or misconfigured transmission policies affecting throughput.
