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.
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 aristaSwFwdIpStatsDiscontinuityTime.
What is aristaSwFwdIpStatsOutFragFails?
Counts IP datagrams that were discarded because they required fragmentation but could not be fragmented—for example, IPv4 packets with the DF (Don't Fragment) bit set or IPv6 packets exceeding the outgoing link MTU. Elevated counts may indicate MTU configuration issues.
