ipSystemStatsOutFragFails
Module: IP-MIB
OID (symbolic): IP-MIB::ipSystemStatsOutFragFails
OID (numeric): 1.3.6.1.2.1.4.31.1.1.28
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of IP datagrams that have been discarded because they needed to be fragmented but could not be. This includes IPv4 packets that have the DF bit set and IPv6 packets that are being forwarded and exceed the outgoing link MTU.
When tracking interface statistics, the counter of the outgoing interface is incremented for an unsuccessfully fragmented datagram.
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 ipSystemStatsDiscontinuityTime.
What is ipSystemStatsOutFragFails?
The number of IP datagrams discarded system-wide for a given IP version because they needed fragmentation but couldn't be fragmented -- e.g. IPv4 packets with the Don't Fragment bit set, or forwarded IPv6 packets exceeding the outgoing link MTU.
