I/O error for SNMP PING

Tivoli® NetView® for z/OS® users can issue a PING request by using SNMP PING. SNMP I/O error problems are reported when a major return code of 2 (internally detected error) and a minor return code of 4 (some I/O error occurred) are received when issuing an SNMP PING. This type of problem is generally caused by an error in the PROFILE.TCPIP data set.
