ipIfStatsOutFragReqds
Module: IP-MIB
OID (symbolic): IP-MIB::ipIfStatsOutFragReqds
OID (numeric): 1.3.6.1.2.1.4.31.3.1.26
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of IP datagrams that would require fragmentation in order to be transmitted.
When tracking interface statistics, the counter of the outgoing interface is incremented for a successfully 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 ipIfStatsDiscontinuityTime.
What is ipIfStatsOutFragReqds?
This counter tracks the number of IP datagrams that exceeded the interface's MTU and had to be fragmented to transmit. The counter increments only on the outgoing interface when fragmentation succeeds. Network operators monitor this to identify MTU mismatches and optimize fragmentation patterns in the network.
