N3T_Input_Discard_Pct

Input discard percentage is calculated using the total number of IP input segments that were undeliverable and discarded, divided by the total number of IP segments received since the TCPIP stack was initialized. Segments can be discarded due to hardware errors, addressing errors, unknown protocols, and other errors. Excessive discards waste network resources.

A trace might be needed to isolate the source of the discards. See the IBM(R) z/OS(R) Communications Server: IP Diagnosis Guide.

Formula: Input Discard Percentage >= 5
