If you want to continue to use community-based security but take advantage of some of the new SNMPv3 functions, or if you want to use the new SNMPv3 user-based security along with community-based security, you need to migrate your current configuration, defined in PW.SRC and SNMPTRAP.DEST, to SNMPD.CONF format. For information about the necessary steps for migrating PW.SRC and SNMPTRAP.DEST to SNMPD.CONF, see z/OS Communications Server: IP Configuration Reference.
