N3T_Fragmentation_Failure_Pct

Fragmentation failure percentage is the total number of IP output segments requiring fragmentation that could not be fragmented, divided by the total number of IP segments requiring fragmentation. Fragmentation failure is caused when the no frag bit is set in the segment. Fragmentation allows delivery of a message through intermediate hosts that do not accept larger segment sizes.

If fragmentation failure is excessive isolate the source of the segments with the no frag bit set. Use the diagnostic procedures outlined in theIBM(R) z/OS(R) Communications Server: IP Diagnosis Guide, and take corrective action.

Formula: Fragmentation Failure Percentage >= 5
