Module: MPIOS-MIB
OID (symbolic): MPIOS-MIB::sysIfOutDiscards
OID (numeric): 1.3.6.1.4.1.5651.3.20.1.1.300.1.100.1.13
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of outbound packets which were chosen to be 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 sysIfOutDiscards?
This is a running counter of outbound packets at this row's IP precedence level that were deliberately discarded, for example to free up buffer space, even though no errors were detected. An admin seeing this climb for a given priority class is looking at congestion or buffer pressure affecting that class's outbound traffic.
Examples
